Cool. I'll get CR's after I run these pig pads to the ground.

That ballpark fits most "track" BRZ/FRS. If you're street driving as well, you'll probably need to compromise on something unless you care more about performance than tire life. (We're talking maybe a 30% decrease in life at most)
I have heard from some that this car likes more rear camber. I'm at -3 front and -2.5/-2.7 rear w/o any adjustments in the rear and 0 toe all around. Would you recommend trying equal camber -3 F/R or go with a degree less camber in the rear, -3/-2 F/R?

Thanks

You guys have distinctly different approach to turn 1 and 2. He stays wide on 1 then come inside more on 2 while you keep on the inside approaching 1 then go wide entering the hairpin with a late apex. He seems to kinda double apex the Andretti turn. I wonder who is carrying more speed exiting the hairpin? Very nice. you guys look like you are going the same pace using different lines, tho you look like you are using more tire than he is. Just my newb observations.

I miss the first apex in T2 on purpose, and trailbrake into the corner.

More rear camber = more rear cornering grip, less "exit under power" grip.

Our settings are based on wear patterns and pyrometer readings. As always, YMMV.

Turn 2 at MRLS has lots of different lines, all of which are valid; it is just one of those kinds of corners. Makes it really interesting when you have a coach one day tell you a different line from the coach the day before

What you are seeing is my failed attempts at doing a double apex through turn 2. It's tough getting the car setup in a straight braking line through the first apex. With a double (semi) apex, I do find that I gain a lot of ground on guys doing a single apex because you are braking deeper into the turn. Since then, I've figured things out better, but with my boxster. I do late apex 2 and 3, which allows as much velocity as I can exiting the corner. It's all about exit speed. Rehabjeff is running 225 width BFG rivals (1.1-1.2G) on his FRS, and I'm running 215 width MPSS (0.9-1.0G) in the BRZ. Jeff seems to have mastered turn 6, whereas that is my weak turn. It's a very awkward turn for the 86. Do you shift to 4th then back down to 3? Do you stay in 4th? Do you stay in 3rd and bounce off the limiter? Jeff stays in 3rd, Pobst stays in 4th. I'm all over the place...

Yep it looks like you make up a lot of ground on rehabjeff with your double apex line. He pulls on you in the straight, but you're constantly at his rear bumper by the end of T2/3. There's a similar hairpin at one of the local tracks I go to. Thanks for the video -- it's given me an idea on a different way to attack that turn.

I just came back from Watkins Glen with your recommended -3.4f and -2.7r camber with zero toe - fantastic setup for my needs. Wasn't pushing hard as it was my first time on track with the FR-S but I managed to get within half a second from my fastest time in Lotus Elise...and I barely heard the toyo ra1 tires...and Ohlins R&T worked great...and there is so much more left to explore...love this car on track and it's great as a daily with Ohlins.

AP Racing Sprint BBK with XP12 all round worked great for late and hard braking...and the Jackson Racing SC worked great.

Thanks for your suggestion @CSG Mike!

Seems to be the popular choice of line through there, but do you also stay inside before hitting T1?

From a very fast AMA pro, not me. He says to always stay in the higher gear when you are between gears. It will force you to carry more speed out of necessity. Sound like good advice to me.

There is a spot where you can apply this approach at SoW going CCW, I do this in GT6 in a bone stock '12 FR-S seems to be the fastest way around there. If only I had the 'Ca-hones' to do it in real life. IF you dont slow down fast enough you will get launched out of a banked turn sideways. Should be worth some good air time. lol I seem to be about 13-15 seconds faster in GT6 than real life with better tires and alignment....

Makes sense, the problem is the exit of turn 6 is a BIG uphill climb. When I stay in 4th, I am lugging up the hill because I don't carry enough speed through the corner like Pobst does. Staying in 3rd allows you to keep the momentum going, but you sacrifice some peak speed coming into 6. If I sharpen my line, then maybe I can carry the speed through 6 that allows me to stay in 4th like Pobst.

Well that makes me feel better that I can't manage to hit the first apex end up trailbraking. I guess that's a good way to do it, then. LOL

I try to mimic this guy, but can't :

I'm a bit better here, but still not hitting it like the guy above

1: what are the red things under your gas pedal?

2: did you ever figure out what the white car was?

3: the GT3 RS driver had a $500 bet on the line for his lap time. Do you feel like that bet provided additional motivation to push his car and himself harder than he otherwise would have? Please cite your sources using mla format.

Awesome video, that looks like a lot of fun.
