Just back from the 3 day Advanced Road Racing course at Bondurant. I have been doing track days since 1997 and racing (Porsche Club, HSR, etc) since 2005, but this was my first ever course like this. There were a total of 4 students with 2 instructors for the class, so you got a lot of 1:1 instruction. 2 of us were in the ACREs, and 2 were in TA2.0s.


Arrival & Day 1
Day 1 started with a heel/toe exercise. Basically the instructors would have you accelerate down the straight, do a 3rd to 2nd downshift with a heel/toe, brake, and then repeat. Given that this was the advanced class, everyone could already do a decent heel/toe.

Next up was the small oval. This exercise was to get some basics of downshifting, braking, turn in, apex/mid corner and track out. Given how short the oval is, you did a lot of laps in a very short period of time. It was exhausting! While its not something that was terribly useful, it did get my mind back into a driving mood after not having done any event for 18 months.

Right before lunch was the Bondurant main track. This is a very tight, mostly 2nd gear, some 3rd gear course. We did a ride around first with the instructor, and then some lead/follow, with the instructors in Challenger 392 SRTs, and us n our car. The track is short, 1.6 miles, but has a ton of turns (a very "busy" track). Once the instructor liked what you were doing, he would point you by for open track. The rest of the day was open track, with various laps of solo, ride alongs as well as having the instructor drive. I tend to learn best from the right seat, so riding with my instructor was most helpful to shake the rust off and get back up to speed.


Day 2
Day 2 started with a brief visit to the skid pad, with the special skid car. Took a few laps to get used to driving such a goofy setup, but eventually was straight forward. Then back to more open track at the Main track. Right before lunch we headed over to the east track (aka Wild Horse Pass, aka Firebird). This is a "real" track with higher speed corners, though overall its still a pretty slow track with a max speed of ~115 and avg speed of ~75. But it is still a decent little track. Session started out the same with us riding with our instructor, now in a Hellcat, followed by lead/follow, then open track. The instructor used an AIM solo to collect data and then review after a bit.


Day 3
The last day started with more laps at the east track and data analysis. I had to leave at noon, but the afternoon was to be some racecraft session such as passing, offline driving, etc. Given I've raced quite a lot, I was fine missing this. By the end of the day I ran a best of a 58.9, while my instructor managed a 58.3 but with me in the car. Given I hadn't turned a lap since fall 2015, I was happy with this. With more time in the car and experience at the track, 57s are definitely within reach.


Overall impression
While I bought my ACRE last year, I have yet to drive it in anger. So getting some seat time in an ACR was the main reason I signed up for this class. All of my HPDE & Racing experience from the last 20 years is in lower power / lower weight cars, like my 92 Porsche 964 cup (~265hp and 2500lbs). And I've never driven anything with an aero.

From the car point of view, all I can say is holy crap, the ACR is freaking awesome! It actually took me much less time than I expected to get used to having 645hp, and by the end of the course I was thinking that another 100hp would be nice. The power is very linear, and unless you try to break traction on purpose, the rear sticks incredibly well. And the cornering speeds of the car are just awesome. And its so predictable, tossable even. The CCBs are crazy good, with zero fade even after many, many laps.

As for the school, I feel it was worth every penny. You get a ton of track time, to the point I would pit just to rest. And the individualized instruction is great. Based on what I saw, there is a big difference between this class and the Grand Prix class, which appeared more crowded with less experienced drivers. The instructors (Mike & Nick) were both great as well. Even and experienced racer would get something out of this course IMO. They also keep the car running great. I got an entire set of fresh Kuhmos on Day 3 and new brake pads as well. So you aren't driving around on used up tires and brakes.

Nice! Glad you had fun! The track looks tiny compared to what i'm used to - imagine if you really had some space for it!

I have still yet to take up the offer that came with the car - need to take a look at that!

It's a really small track for sure, but large enough that it didn't feel like a glorified auto cross. It definitely made we want to take my car to big track like Watkins Glen, Mosport, Sebring or Road America.

Thanks for taking the time to post this detail.

2nd gear mostly, and some 3rd gear, yikes. That's a freakin slow track.

I guess my dream would be to get advanced instruction in the ACRs true aero capabilities, I guess not at this one.

And that first day, meh. Seems like you described it perfectly, if you've been out of a race car a while, it'd be a great way to jump back in, in a fun way and cool way.

Hec, it was worth it for those pics, looking good out there!

I'm a little surprised you didn't get to run on the West Track.

I think I hit 120ish in 4th going down the straight and almost going into 5th if I recall, I need to look at my videos again.

The ACR is a real treat and leaps and bounds faster than the 2.0 T/a. Bob Bondurant was in the ACR for a few laps during my session and he actually pointed me by in the oddest spot. Haha. I said to myself, if Bob is giving me a point by, I'm taking it!!

I also agree on the track time! My longest session on West ran 50 mins! I was determined to squeeze every second out of my time on the track. The only reason why I pitted was... I almost ran out gas.

It's really sad I will not be able to do the advanced school with the ACR when I want to return in 2 years. O well...

For those that are not high level amateur or pro drivers, the Bondurant track is a great learning tool since it is a learning track. I don't consider it a great race track, but as a learning track it is superior. I really don't think you'd want student drivers learning increasing radius, decreasing radius and constant radius apexes at the 4th gear speeds the Viper is capable of with aero. I look at it this way, if you can't hit your apexes perfectly at 2 or 3 gear speeds, you'll be screwed if you try it at 4 gear speeds.

The circle track part of the exercise truly shows how much concentration short course stock car drivers need to have as you never get a chance to rest. I loved it. Bondurants skid car is the only school I know of that has such an apparatus.....it was awesome.

Look up VenomV's thread on Bondurant as he hired their professional driver for private one on one driving at what I'm sure was a very high level of speeds and training.

Colin, thanks for posting! Looks and sounds like you had a great time! I took the 3 day school about 20 years ago and we ran that oval, back then it was in mustangs and I last about 1 minute in the back seat on the skidpad. That East Track looks fun and appreciate you posting the video. I'm heading over there in 3 weeks for the Viper Tracks event and happy to see that track is better than I thought. Best wishes and thanks!! Mike

Congrats on the 58.9s lap time! That is smoking fast for East Track. The nasa record is 56.416 and that's in a 2300 lb Evo with 800hp and even crazier aero than the ACR.
What are your home tracks? You will be terrorizing them soon!
