Road Atlanta Track Day with CCA

Earlier last month I revisited Road Atlanta for the Spring DE with the Peachtree Chapter of the BMW CCA.  This was my second time out with this group at Road Atlanta, last fall being my introduction to this amazing track.

The weather really cooperated for this weekend, with cool temps and sunny skies.  The track surface seemed pretty decent, though I couldn’t seem to break my previous best of 1:47 in the ’98 M3.  I seemed to plateau in the 1:48s, but not for lack of trying.  I’m sure there’s a second to be found, but it would take a near perfect lap.  I’m at the limits of grip at several points on the course.  I could use a little more front grip as well, I forgot to try playing with the front sway bar (not even sure what stiffness it’s at now.)

I also linked up with another track junkie from Texas who I had run many tracks with.  It was great catching up, though there was no catching up with him on track.  I also got to put a few of my Christmas presents to use.  We set up the 12’x12′ canopy to grant a little shade and grilled out for lunch both days on the portable propane grill.  All in all another enjoyable time at Road Atlanta and no blown power steering lines to boot!

I didn’t grab a whole lot of video and a few times the GoPros failed me, but here’s a full session from Sunday, 8 March 2015 in the A Group:

Chin Motorsports @ RDATL 30NOV14

My last trip to Road Atlanta was my first time at the Braselton, GA track, and it instantly became my favorite course.  The combination of flowing rhythmic sections, coupled with big elevation changes, and just the right amount of fast sections make it a great track for even street oriented cars like my E36 M3.

E36 M3 & Ferrari Challenge F430

I signed up at the last minute, literally the day before the event began, but was fortunate to get a spot on Sunday.  I just wanted one day, something Chin usually does for solo’d drivers.  Since I haven’t run with Chin east of the Mississippi, I was given provisional solo status, which would mean a check out ride with an instructor in the morning.

I ran the track during the morning warm-up by myself, just to make sure I remembered the track and the car was alright.  Then for the first session I had an instructor for the first session.  Strange that I had been grouped into “Blue” on all previous Chin events, but now I was running in Green/Yellow.  I suppose they are a bit more picky given that they are actually selling out their groups at these more established tracks than the newer ones they were just starting to run in Texas.

The local Nissan GTR club must have organized a group run, as there were tons in attendance.  Plenty of novices too, which made things a bit interesting given their speed capabilities.  Fortunately everyone played nice, though we were limited to passing on the straights, which hadn’t been the case when I ran in September with the CCA.  So some of the higher powered cars had to be a bit judicious with their throttle application and allowing slower cars like my 16 year old BMW around.

The weather was perfect for the weekend, nice and cool, not cold and no rain.  The track was as grippy as I remembered it from last time, and the car ran well.  The power steering lines even managed to stay connected!

My lap times also improved a bit, managing to break into the 1:47’s from my previous best of 1:50:58.  Actually that’s quite a bit of an improvement, and I think I probably did a bit better.  I had purchased a new phone after my last track day and forgot to pair it to my external Bluetooth GPS receiver, so all the times were based off a 1hz refresh rate.  So essentially the exact points where I crossed the Start/Finish may be skewed.   Either way it was fun to get back out on the track, especially one as rewarding as Road Atlanta.

My cousin even came down from Upstate SC to spectate, taking his E46 M3 out for the parade laps.  I even convinced him to take a ride with me during a session, something my father continues to refuse after his life altering experience around Texas World Speedway in a very fast S52 M Coupe.

And of course I recorded some video, though the data is a bit off due to the previously mentioned issues with my GPS receiver.

Auto Trackday Monthly Interview

Several weeks ago I received an email from Michael Allen, who had expressed interest in conducting an interview for his website, AutoTrackDayMonthly.com, which was just getting off the ground.  Michael shares a love for track driving and wanted to share it with others by way of a website dedicated to the hobby.  Part of this is a reoccurring feature where he interviews other track day enthusiasts (like say Harold of Harry’s Laptimer fame.)  I of course agreed, and Michael shot me a list of questions, which I must say were very well thought out.  He also asked if he could publish some of my articles, which again I was happy to oblige.

The following is the complete interview, which can also be found in its orginal form at this link: Eat, Sleep, Tinker – Auto Trackday Monthly 

AutoTrackdayMonthly.com

Backseat to a LongbowChad Morehead, author of the blog Eat, Sleep, Tinker, was a helicopter maintenance pilot in the U.S. Army so he knows a thing or two about operating a high performance machine and wrenching on it as well.  Chad has discovered track days (more accessible than piloting an Apache Longbow) and has a wealth of information on car preparation and maintenance, tracks, and track day driver, and makes sensible car modifications.  We conducted a Q and A with Chad for our monthly Track Driver feature.  Here it is:

Tell us about piloting a helicopter. What type of helicopter did you pilot? What is the job of a Maintenance Test Pilot?

I started flying when I was 15, small single engine Pipers and Cessnas.  I always had a love for flying, really a love of anything mechanical.  My father was also a test pilot in the Army, flying Hueys and Blackhawks.  When it was time to look at colleges, I knew I wanted to serve in the military, with an ultimate goal of becoming a helicopter pilot.  I went the ROTC route, and was lucky enough to be assessed into Army Aviation starting out of small Bell 206s and OH-58s, then moving to the “Big Rig” AH-64D Apache Longbow. 

I flew those as a young lieutenant and captain, then requested the maintenance test pilot course after my first deployment.  Again, I was lucky enough to get a slot.  As a test pilot, and maintenance officer, I was destined to command an aviation maintenance company, which is responsible for maintaining the unit’s fleet of aircraft.  While my main role was the manager of the unit’s operations, I had a secondary responsibility of conducting test flights and various other maintenance checks.  Essentially anytime an aircraft has maintenance performed on it, it must be checked out by a test pilot before being released to “peter pilot” and normal everyday missions.  Which means I spent a large chunk of time troubleshooting the aircraft on the ground, rather than actually flying it. 

I have spoken to several pilots who became involved in motor sports. They tend to find driving a car on a track less compelling than piloting an aircraft.  They speak of too many constrictions when comparing driving a car on a track to flying.  How do you compare track day driving to piloting an aircraft?

Nothing is going to fully compare to flying an advanced attack aircraft, but you can’t exactly go take one for a spin whenever you want.  But really pushing a car 10/10th’s on the track makes for a close second.  You certainly get some of the same pucker factors on occasions where you are courage limited rather than traction limited (or sometimes when both occur.)  I find myself having to dial back my aggressiveness, as I’ve built up a threshold for hairy situations in my day job, and I don’t quite have the driving talent or car to go along with that aggression. 

What makes them comparable is that speed is all relative.  250mph at 500 ft doesn’t feel any faster than 120mph on the ground surrounded by things to hit.  You end up getting the same kind of rush.

How did you become involved in track days?

I was always into cars, starting off mainly with 4x4s and trucks.  But I also had a love for sports cars, especially the BMW M Coupe.  I had coveted one since the first time I saw one on a pedestal in the Greenville-Spartanburg Airport’s baggage claim as a young college student.  Of course I couldn’t afford one for a long time, but I never forgot about it.  Then in 2011 I ran across an advertisement for a low mileage example in Houston, TX.  I decided to check it out and ended up buying it. 

I now had a sports car and it was a BMW, so I joined the BMW Car Club of America (CCA.) shortly after that I deployed for a year to Afghanistan.  My car sat idle, while I spent my free time researching upgrades for the car.  When I returned, I went to work on the car, making several improvements.  Of course, what’s the point of all this performance potential if you are only ever going to drive it on the street?  Around March 2013 I was browsing the CCA’s website when I noticed they had an upcoming track day event at Motorsport Ranch, in Cresson, TX.  This was my opportunity to really see what the car could do, so I signed up and from there, like many others, was immediately hooked.

Tell us about your track cars. What do you drive? How do they compare?

Prior to purchasing the M Coupe, I had picked up a 2002 Toyota MR2 Spyder, another low production sports car.  This was my first project car.  There’s very little original to that car, it’s been through several revisions.  I swapped in a 2ZZ-GE and six speed, which then led to a Rotrex supercharged 2ZZ, then an LSD was added, then full bracing, then a roll bar, then a fully built 2ZZ, so on and so forth.  The car eventually put down 311rwhp, all from 1800cc’s!  Leading an RX-7, Boxtter, and BRZ at MSR Cresson

Unfortunately, with all this constant work, the car wasn’t available for most of my track days, so I continued to drive the M Coupe.  The M Coupe has coilovers, upgraded bushings, lower gearing, headers and a tune, making it a very potent car.

I eventually got the MR2 out to the track; essentially just enough to shake it down and see what needed adjusting.  I ran a square tire setup rather than the factory stagger.  My first outing, running the 3.1 mile configuration at Motorsport Ranch, revealed just how much more nimble the car was than the M Coupe.  The MR2 would rotate faster than you could think, making for some pretty epic spins and tail-out driving.  Despite the handling, the car was quick.  I was easily besting my times in the M Coupe, of course the NT01 rubber helped. 

Unfortunately another track day later, this time running the 1.7 mile at Cresson, didn’t end so well.  I had an engine failure, which after pulling the plugs, appeared to be the result of dropping a valve in the #1 cylinder.  Later, following a tear down, it was discovered that the tip of an exhaust valve stem had broken completely off.  So now the MR2 sits torn apart once again, awaiting an upgraded valve train.

Back came the old reliable M Coupe.  Since I never intended to transform the car into a track weapon, it still rides on stock wheels and staggered street tires.  Some additional negative camber up front helped cure a lot of the understeer, but it still plows, requiring a healthy dose of trail-braking on turn-in.  The car is outfitted with a very old design rear suspension, utilizing the same semi-trailing arm suspension that can trace its roots back to the BMW 2002.  It’s a bit quirky, you never ever want to lift in a corner, as it’s very prone to trailing throttle oversteer.  The advantage is that it can really put down the power coming out of a corner.  Even on street tires, I could run with E46 M3s running NT01s and similar DOT-R tires.

Do you aspire to racing? If not, why not?

I haven’t been at the track driving game for very long, just over a year in fact.  With all the tracks available in Texas, I’ve been on an accelerated regimen, trying to make my way through the ranks as fast as possible.  During the last BMW CCA Fall DE we were notified of an upcoming Club Racing School to be held at Texas World Speedway.  It was open to the Advance+ (open passing) students, but I was very interested in attending.  So I asked the chief instructor if I could get a waiver.  He sent me out for a session with an instructor to see how I did, and luckily I passed the scrutiny. 

The club race school was a blast, completely different to what I had been accustomed to with DEs.  Rather than passing with point by’s, we were going into corners two and three wide, passing wherever you could fit the car.  We did several drills, then practice starts, and then finished the weekend with a simulated race.  We had no instructors in the car; instead they were alongside us in their actual race cars.

It was just a taste of what a race is like, but like my first time at a DE, I was hooked.  Rather than trying to find the perfect line and avoid all traffic, you are having to find the line that is available and denying that line to your competitor.  So now I’ve got a caged E36 325i chassis sitting at my house, awaiting its eventual build up to a true race car.  I realize that I have a long way to go as a driver, but my goal is to eventually participate in as much racing as possible.

What has helped your development as a driver?

Just getting out there.  I, like most gearheads, spend a great deal of time reading the various online forums.  This has helped some, but I really just needed more time behind the wheel.  I’ve also picked up several books on the subject of performance driving.  I take these with me on track weekends, reading them at the hotel after a day at the track.  I found that it helps me to visualize what I need to do and also put into words what I’m feeling through the car.  But perhaps the best aid is having a good instructor.  I haven’t had a bad instructor yet, but there are some I just “click” with better.  Find those guys (or gals) and pick their brains.  A good instructor will be willing to teach you just as much out of the car as in it.  Even if you are a solo student, ask for an instructor for at least a couple sessions over the weekend.  A second set of eyes can do wonders, especially if it’s a new track.

What suggestions would you offer to someone who is new to track day driving?

MR2 #229 Front LeftTake it slow, drive within your talent and comfort zone.  The car is only going to go as fast as you make it, so don’t feel obligated to stay with faster cars.  I’ve spun too many times trying to stick with another car (an M Coupe will not stay with a McLaren).  I’m not learning anything from that.  I would also suggest holding off on upgrades to your car until you really know what it needs and where you want to go with the sport.  I’ve wasted a lot of money on parts I thought would make the car better, only to find out that it’s been tried before.  There’s not much new under the sun, and I guarantee someone at the track has been down the path you’re heading.

What suggestions would you make to someone who has plateaued in his or her development as a driver and wants to get back on the track with their progress?

I’m still very new at performance driving, so I tend to learn or improve every time I go out.  Even so, there are things you can do to ensure you continue to improve.  Taking a ride in the right seat is one.  From the passenger seat you are no longer task saturated with nailing the perfect heel-toe downshift, you can sit back and see the driving line.  There’s a saying I hear often from instructors; “speed comes naturally” and it’s absolutely true.  If you are forcing it, trying to drop times, more than likely you are tensing up, making mistakes, and overdriving the car.  Dial it back, concentrate on the techniques, and you’ll see times falling without even thinking about it.  I’ve found myself putting down my best times when I was just relaxed about it, still focused but relaxed.

Do you use data logging and video as part of a self-coaching regimen? How do these help driver development?

I use simple apps on my Android phone, in conjunction with a 10hz GPS, and of course video from a GoPro.  The phone app provides immediate feedback in the form of sector times.  A brief glance of the display tells me if that different line is actually helping or hurting.

The video is helpful in seeing things that you would normally miss from the driver’s seat.  I’ve sworn up and down that I did things a certain way in the car, only to find out later from the video that I hadn’t.  It provides a good way of seeing where you are making mistakes and where time can be had.

Tell us about some of your mechanical projects on your track cars.

How much time do you have?  I’m always tinkering on something, whether it’s the track car, race car, daily driver, or tow rig.  I am a stickler for preventive maintenance, which I suppose comes from my aviation background.  I can’t stand leaks, cracking rubber, or rusty bolts, so I’m always replacing something. 

Then there’s the never ending goal of just making a car perform better, tweaking that last tenth out of suspension setup.  I also am very much OCD when it comes to cars, I can’t stand loose wires or shoddy work, so I spend a great deal of time making everything just right.

You have an excellent blog on your track driving and tinkering career. How did you come to develop that?

Thanks!  It’s still very much a work in progress, and I find myself neglecting it for time spent in the garage or behind the wheel.  Once upon a time I did web design on the side, mainly just to supplement my beer fund as a poor college student.  So that’s where I learned a few things about making websites, in fact I had tried (and failed) a few other websites before.

Like most automotive enthusiasts, I had compiled a healthy number of forum accounts.  I was active on the boards for every site related to the cars I had.M Coupe Rear  I even helped start up and run one for the Nissan Titan.  But it became more and more of a chore to organize my projects or “build threads” across so many sites.  I wanted something centralized, that I would have control of.  That gave me the idea of just starting a blog that would contain everything I was into, allowing me to easily dial up a past project.  I figured it would also benefit others who may be interested in taking on a similar project, modification, or maintenance.  

On the blog, there are some informative articles on track car preparation. What advice would you offer on preparing a car for a track day?

Preventative maintenance is paramount.  Your car should be in tip top condition.  You should start with fresh fluids throughout.  BMW has a notorious “lifetime” lubricant in their transmissions and differentials.  If your car is older, chances are it’s in need of a transfusion.  Things like suspension bushings, bolt torques, and fluid lines should be checked.  Find out, via online searches, what the weak point and common points of failure for your car are.  If your car is prone to subframe mount failures (like most BMWs) then check the welds.

That’s what I would do for my first ever track day.  If you are still on all season tires, you likely won’t overextend your brakes.  Once you see how you like track driving, and you will, you can begin with upgrades.  If you move to better tires, you’ll also need better brakes (or if you have better brakes, you’ll likely out brake your tires.) 

My first event exposed the OEM brake pads and fluid on my M Coupe.  It surely didn’t help that I was a novice and probably over-braking, but I ended up with a lot of fade.  You don’t need a big brake kit, or even floating rotors, but a set of performance pads and fluid will go a long way.

Another item you should look at is the alignment.  A quality performance alignment can make a huge difference on just how easy your car is to drive hard.  Stock alignments traditionally lead to understeer, and are made to help a car track straight down the road with little steering input.  A good shop that knows what they are doing, can dial out a lot of understeer and help the car turn better.  But for your first time out, I would just recommend you have a stock setup, predictable understeer is better than an unpredictable bad alignment.

I have installed brake ducts and a fan on my transmission cooler.  Can you suggest a few high impact tinkering projects for people to try on their track cars?

There are so many variables between different cars, different tracks, and different drivers that this makes for a very difficult question.  I prize reliability above all else (besides safety).  Do whatever you can to ensure you get your car through an entire weekend of track driving.  This goes back to preventive maintenance and having pads and tires matched to their intended use.

But if I had to pick something beyond brakes and tires, I would say a seat and harness.  My M Coupe still has stock seats and belts, whereas the MR2 has 6-point harnesses and Lotus shells.  If you are just getting started, you will be amazed by just how sore and tired you are after one day at the track.  With stock seats and belts, you have to flex your muscles the entire time around a corner and during braking to keep yourself in the seat.  So rather than allowing your body to relax and receive tactile feedback, it is tense and prevents making smooth inputs.

Tell us about the tracks you have driven on?  Which is your favorite and why?

Texas has a very healthy selection of tracks, as well as numerous organizers for track days.  I’ve been very fortunate to have experienced so many track days, at so many tracks, in so little time.  I’ve driven the Motorsport Ranch 1.7 mile in both clockwise and counterclockwise configurations.  I’ve also done the 3.1 mile track there on a couple of occasions.  This facility offers a lot of variety, with almost all the turns allowing for good passing or setting up of passes.  The surface is different depending on what section you are on, but very slick under damp conditions.  There’s also a lot of off camber corners, which take a bit of courage to really carry speed through.  Running the 3.1 mile provides for impressive elevation changes as well, with only one slow 2nd gear corner.

Titan towing M CoupeTexas World Speedway is another great track, having started life as a stock-car super speedway oval.  The banked oval still forms the front straight, but now a 2.9 mile road course is the main attraction.  The surface is a bit rough in spots, with some bumps that may catch you off guard.  The track is fast, especially when run in the clockwise configuration, which has you following a long sweeper onto the front straight.  I’ve spent more days here than anywhere else, as it’s less than two hours from my house.  It’s also served by numerous organizations.  BMWCCA, NASA, PCA, Performance Driving School, Drivers Edge, and Chin Motorsports all run this track pretty regularly.  They also have occasional “open track days” where there are no sessions, and you can just go on and off the track as you please. 

Also not too far away is Harris Hill Raceway, in San Marcos.  It’s a smaller facility, which mainly caters to paying members.  Its small paddock prevents the larger organizers from having events there, but occasionally they open it up to track days.  I’ve run it twice, both times in the M Coupe.  The track surface presents some problems, as the ground has settled unevenly in several areas, producing a very bumpy ride.  I barely fit in my M Coupe with a helmet on, so I’m constantly banging my head off the ceiling around the track.  Despite this, the configuration makes for some very fun driving.  It has a very cool elevating corner, which dives down into another corner. 

Last month I traveled out to New Orleans for a weekend at NOLA Motorsports Park with Chin Motorsports.  This is an absolutely beautiful facility.  The pavement is new, the curbing is where you’d expect it, and plenty of spots to pass.  There is zero elevation change, it is Louisiana after all, but the configuration keeps it interesting.  I really liked this track, I feel it would be great for racing as well. 

My most recent track day was at the Circuit of the Americas, or COTA to most enthusiasts.  This F1 purpose built track is on many folks’ bucket list, and I wanted to drive it from the moment they broke ground.  Unfortunately, the management knows this as well, and the prices reflect it.  A few organizations have run the track recently, but only the CCA has done so at a price I was willing to cough up.  Like NOLA, the track surface is in mint condition.  Grip is consistent throughout, even when cold and slightly damp.  The layout of the track has sections I really love, but others that are very frustrating.  It’s quite difficult to setup passes, as the straights begin and end with very slow corners.  The straights are also very long, giving the feel of just hauling down a highway, followed by slamming on the brakes for a tight corner.

Just for its variety, I would say Motorsport Ranch in Cresson is my favorite.  That said, they all bring something different, and that’s what makes going to a new track so enjoyable.  I’m really hoping to try out a few new tracks this year, such as Eagles Canyon, Hallett, and MSR Houston.

NASA HPDE at TWS

I finally made it out to a NASA event, this time at TWS.  I’d been trying to make it to Eagles Canyon with them since I haven’t driven it before, but work schedule conflicts prevented it.  I still wanted to get at least one NASA event in before I left Texas, so at least they’d have me on the books as participating and I could get a feel for the organization.

National Auto Sport Association

I suppose before I go any further, I should explain that this is NASA as in the National Auto Sport Association, not the National Aeronautics and Space Administration.  They, as the name implies, are a nation-wide sanctioning body for numerous classes of road course and autocross racing.  They also run a DE (Driver’s Ed, Driving Experience) called High Performance Driving Event (HPDE) which is practically identical to what I have been running with The Driver’s Edge, BMWCCA, Chin Motorsports, and Performance Driving School.

HPDE is the starting place for anyone looking to get on the track and build up to actual competition.  Rather than colors for classification (Green, Blue, Yellow, Red), NASA calls their run groups HPDE 1, 2, 3 and 4.  The rules are nearly identical to the other organizations, with passing being limited to designated straights for HPDE 1 and 2, and open with a point for HPDE 3, and simply open for HPDE 4.

I joined NASA a while back in anticipation of working my way up to actual competition, aka wheel to wheel racing.  NASA is the sanctioning body for the German Touring Series (GTS) as well as Spec-E30, which are two of the most popular classes for BMW’s to run with.  In fact they seem to draw a larger entry than BMW CCA Club Racing does.  It also helps that you can run a GTS car in a CCA Club Race.

Of course before I can even think of going out for wheel to wheel, I need to get much more seat time in DE’s.  And if you are bored with non-competitive DE’s, NASA has Time Trial (TT) classes as well.  These are run essentially in the same manner as the HPDE groups, sometimes even sharing the same session with HPDE-4.  The difference; TT is racing against the clock.  Quickest time in a session wins, pretty simple, although it gets a bit more complicated when classifying your car and making it competitive.

So you can see there are essentially steps to take towards racing, in addition to a required competition school before earning a license.  Based on my experience, I signed up for HPDE-3, which sounded like the equivalent of a “yellow” run group (or “blue” in Chin’s case.)  I also only signed up for one day, since I would be taking the M3 sedan on some already torn up Hankook Z12’s from the previous weekend at TWS.  We’d be running clockwise this weekend, so I’d only be evening out the tire wear.

Upon arrival at TWS on Sunday morning, one thing was immediately apparent: NASA draws a much larger crowd.  I thought TDE events were big, but I’d yet to see this many cars at the track.  The entire paddock was full, as was the infield straight away (which is normally wide open and can be used as a slalom) and even the VIP stands had trailers and campers scattered beside them.

The other thing that was readily apparent was that the racing was the main draw.  The paddock and garage wasn’t full of spotless Maseratis, 911’s, or McLarens.  No it was full of Spec Miata, American Iron Mustangs, and other assorted race cars.  Clearly racing was the main focus and HPDE was just a side show.  I found an empty spot by the pit fence line next to a couple Spec Miatas and dumped my stuff.

After a quick Tech Station inspection I sat in on the morning HPDE drivers’ meeting.  We’d be running HPDE 3 & 4 together, with the TT guys by themselves.  We were given some bright colored stickers to put on our rear bumpers so the faster HPDE4 cars knew they were about to overtake a 3 car, since we were operating under different passing rules.

The rest of the day went like most other DE’s I’ve been to, we had a couple academic sessions in the classroom as well.  I haven’t run clockwise in about a year, back when I was a Green student, so it took a bit of adjustment.  All in all it was an enjoyable weekend.  Most of the folks around me were very friendly, though I didn’t recognize any faces from my previous track days.

The car performed the same as it had the previous weekend running CCW with Chin, though I thankfully had fixed the loose differential axle bolts and shock bolt.  It still was very understeery and didn’t have a great deal of grip.  Running the course clockwise caused the tires to chunk like last time, only on the left side now.  So at least I had symmetrically bad tires.

Below is a video of one of the sessions, showing a three different angles just for fun.

BMW CCA Texas Trifecta ’14 at COTA

I finally made it onto the Circuit of the Americas, after several events of just spectating (ALMS/WEC, Grand-Am, Trifecta ’13).  The track still has that new smell, and its popularity garners some pretty high prices and long waiting lists to get in.  Fortunately the three Texas chapters of the BMW CCA came together again for their second “Texas Trifecta” driving event, and they kept the costs to somewhat less stratospheric level than other organizations.

In order to stand a chance of getting in, I had to ensure I was a “tier 1” applicant, which meant participating in a Texas chapter event in the preceding year.  Good thing I attended the Fall DE at MSR-Cresson with the Lone Star Chapter.  You also had to be a solo qualified driver, which narrowed the pool down further, but the event was still sure to sell out fast.  I registered as soon as I could, knowing this would probably be my last opportunity to drive the track.

Much of the hype surrounding COTA is just that, pure hype.  I haven’t been to any other purpose-built F1 tracks, but from what I’ve seen on TV and in photos, COTA isn’t anything remarkable.  That’s purely from a landscape and amenities perspective, not the track design.  I’ve attended two pro-race weekends there, and I wasn’t exactly blown away.  I left feeling like it was lacking a bit, but as I mentioned, it was still very new at the time.  Over the past year they’ve made some improvements, like adding camping accommodations on the back straight area, near turn 11.  But this post isn’t really about the facilities, it’s about driving the actual track.  That too has been hyped up for quite some time, as you’d expect given how new the place is and that it’s brought F1 back to the States.  I tried to keep my expectations in check, and treated it as if I were going to any other track.

BMW M Coupe at COTA

The Texas Trifecta was spread over three days, Friday through Sunday.  I, taking the cost into consideration, only signed up for Saturday and Sunday.  Due to scheduling of both HPDE and races, there would only be three thirty minute sessions per day, down from the standard four.  Sacrifices must be made right?  The run groups were also fairly large, though they tapered off on Sunday, and the track is pretty big at 3.41 miles.

COTA Track OutlineFor the first three sessions I was paired with an instructor to help learn the track.  As you might expect, it’s not the easiest to learn with 20 turns.  The pit-out puts you right out at the end of the front straight, leading up the hill to T1T1, like T11, T12, and T20 is a very low speed, tight radius turn.  It calls for down shifting to second gear.  With my stock staggered street tires, I will understeer pretty badly without really coming in slowly.  Pitting out presents a bit of a problem if you have traffic coming down the straight at speed, as the blend line carries you all the way to nearly the turn, which puts you far too inside of where you need to be.  T1 through T2 is a flowing downhill bend, accelerating the entire way to the bridge just before the essess.  Not much braking (none if you are braver than me, maybe a slight lift) into T3, slight brake before T4.  It’s essentially a tightening set of essess.  The great thing about this track is that the pavement is ultra smooth and incredibly grippy.  There is also very generous run off room, most of it paved.

You have to look out for the larger orange pyramid-like concrete bumps that are placed at the apexes, which serve to keep racers from cutting the course by too much.  These stick up enough to do some serious damage to a car’s under-belly and suspension.  I tried to cut the curbing as close as I dare without hitting those orange bumps.  T68 provides for a little bit of playing around with the line, I tried a few different approaches.  T7 is tighter than the previous section, and I was continuously flirty with the astro-turf on track out.  T8 is almost like a mini carousal, I don’t think I could double apex it, maybe lengthen out the braking then bend it around for a late apex and shot into T9.  Coming out of T8, I practically just straighten the wheel and clip over the cubing.  There’s really no need to bring it back to the right and then turn in, as you are practically hugging the inside of T8.

Between T9 and T10 is a strip of grey concrete on the right side of the track, providing a good cue for turn-in to T10.  This was great, because if you could see the apex of T10, you were already too late.  The terrain is falling away at this point, so you really just turn in at that grey strip and you clip the smooth painted apex at T10.  The track straightens up just a bit, then it’s hard on the brakes for T11.  T11 is a tight left hand hair pin, leading onto the back straight.  It’s a bit frustrating, as you really want to carry speed onto a straight.  Here it’s practically a drag race from ~35mph coming out of T11.  Cars begin to stack up there, and then some of the first passing finally takes place.  The straight between T11 and T12 isn’t entirely straight either, slightly bowing the right.  Having started at such a slow speed, you really don’t hit anything astronomical, even for such a long straight.  My logs showed I topped out at 138mph before braking for T12, that’s really no faster than the speeds I’ve hit at TWS, even going CCW.

After the boredom of the back straight you have another heavy braking zone, the hardest given your speed.  T12 is another very slow corner.  You’re going from fifth down to second, similar to the T1.  You’ve got a short straight leading to T13, which I followed to the very outside edge before turning in.  I had a very difficult time trying to figure out T13, getting it to where I wouldn’t just plow horribly.  You can almost carry a constant arc through it and 14, but I still never felt like I had it down.  Turn 15 was strange in that it’s really wide leading into the corner, which made it difficult to choose where exactly to place the car.  In traffic I saw other cars taking multiple lines in.  I tended to brake to the outside edge, then sharp turn towards the apex.  It’s not as wide coming out as going in, so you have to be mindful.  Fortunately you can easily see this on approach, as you are essentially doubling back.

Turn 16-18 is essentially a carousal, where you try to maintain a set steering input, then just use the throttle to carry it around the track-out.  When you do it correctly, the car follows the same arc and the apex of T17 and T18 just come over to you.  This is a pretty high speed corner, lots of fun.  I had difficulty really laying on the power, as it would just lighten the front end and I would begin understeering away from the corner.  You really have to use maintenance throttle to get it just right.  I never was quite brave/fast/or have enough grip to push it all the way out the the track out rumble strips.  That’s probably not such a bad thing (other than giving up time), as you have to move back to the right side of the track for T19.  I found (and apparently several others as well) T19 to be deceiving.  At first it looks like any other slow corner, but in fact, you really can carry quite a bit of speed through it.  The orange pylon at the apex is very low and runs in the same direction as the track, so you can actually clip the corner safely.  I spun twice in this corner, my own fault from making abrupt throttle adjustments while turning.  I mentioned it was deceiving, I found myself either going too slow or (on the occasions I spun) too fast.  My parking spot in the paddock was right next to T19, so I witnessed quite a few other cars struggling here as well.  Fortunately there is a lot of paved run off and if you do have an off, pit-in is right there, saving you the embarrassment of getting black flagged.

Finally the last turn, T20.  Like turns 1, 11, and 12, this is a very slow corner.  Back down to second gear and on to the front straight.  I found this corner to be the most power-oversteer prone on the track, perhaps because it leads on to the front straight and I’m just trying to wring as much speed out as possible.  It also is a bit more narrow than you might expect, I was consistently running the outside edge on the astro turf, wishing I had more pavement.  The front straight runs right through the grand stands, starting very flat then quickly rising to turn 1.  You really must use the last bit of that uphill for braking, as the car unloads a bit at the top and you’ll quickly blow past turn in.   That’s it, rinse and repeat.

I found COTA extremely hard on brakes compared to all the other tracks I’ve run.  The numerous slow speed corners following straights require very heavy braking, and it showed with pad fade by the fourth lap or so.  Of course my car doesn’t have true brake ducts, is full weight, and is using all stock brake parts aside from pads and fluid.  If I were to continue to run it in the M Coupe, I’d want to add ducting and perhaps change to PFC 01 pads if necessary.  The PFC 08’s worked extremely well up until about lap 5 where they faded slightly.  Nothing reaching dangerous levels, I just had to compensate by braking sooner (which of course doesn’t help the heat issue.)  I had also added Bimmerworld titanium backing plates, which I will highly recommend.  After the weekend I removed the PFC 08’s and plates, which were completely scorched blue and purple from the heat.  As designed, the plates had prevented the heat from transferring to the caliper, its dust boots looking fresh and untouched.  Likewise, the brake fluid never showed a hint of fading, I’ll give an endorsement to the Brembo LCF as well.

So what are my thoughts of the track now that I’ve finally run it?  It is definitely a great facility, a nice change of pace from running old and bumpy places like TWS.  The pavement is glass smooth, grippy, and easy to drive.  If I were to break the track down into sectors, I could say there are some I really disliked and others I really enjoyed.  You can probably guess that I wasn’t much of a fan of the very slow corners following and starting straights.  Sure they require a fair amount of skill as you try to judge your braking zone, there’s definitely time to be made up there, but I prefer a track that has a bit more flow.  The layout makes it difficult to setup and execute passes on nearly everything but the straights, and those are painful too as everyone is starting from the same slow corner.  Places like MSR-Cresson allow for anticipating and setting yourself up for a pass through several different corners, not so much with COTA.  Since there is a wide spread of cars and drivers at HPDEs, it can make passing even more challenging on tracks with several long straights or high speed sections.  Corvettes and Ferraris will just walk away from me, but then I’ll pull a Miata and be back on them.  Of course the right thing to do is to let the car pass when they catch up with you, but then you wind up sandbagging as to not pass on the next straight.

Another issue I hadn’t even anticipated was the difficulty in seeing the flag stations.  Most amateur race tracks aren’t surrounded by high catch fences to protect spectators, so you can easily see every corner worker from a good distance off.  COTA’s corner stations are behind these fences, which have small openings for the workers to wave the flags.  What this means is that you really don’t see the stations unless a flag is sticking out, unlike most other tracks where you can actually see the workers’ mannerisms and anticipate what may be happening.  It’s not a huge issue, just something to get used to.

Despite these issues, as a whole COTA is a very enjoyable track.  It’s challenging to learn given the size, but not so much as to be daunting or scary.  There aren’t any “oh-sh!t” type corners, where things get out of whack even when doing it correctly.  Smooth on-camber corners with generous run-off and open sight lines definitely add to the enjoyment.  I’d love to run the track again, but not at the prices most organizers are asking.  I’d recommend it as a track you should at least drive once if the opportunity presents itself, but to me it’s not worth the $900-1300 that most are asking.  Hopefully the prices will come down and availability go up as the “newness” wears off and more organizers get involved.

As always, I brought along a couple GoPro cameras to record my laps.  I used my Android phone again to pull data from a Bluetooth GPS taped to the dash, then used the output as an overlay.  Unfortunately I didn’t get all the sessions due to my GoPro Hero3 Black Edition failing on me, but was able to get some interesting footage with the two remaining cameras (White and Silver 3+)  The video below uses the standard mounting position behind my left shoulder so that you get a view of what the steering wheel is doing.

And this video has the main camera mounted on the roof.  This was a pretty fun session, with a little back and fourth with an E46 M3.  I couldn’t hang right with him, as he had more tire than me, but fun nonetheless (despite fouling up a few downshifts.)
