I am the driver in car 156. I struggled to get on schedule day 2 and my codriver was on fire but I am really happy with the car.

Setup has been pretty simple. Karcepts thick bar in the back at full stiff, 275 bstones, zero toe front and rear. I still have the stock exhaust on it, it was like watching a Tesla leave the line it was so quiet.

Nice job for Jim and Jesse. We ran the thick Karcept rear bar at 3 and I still had the big moment on run 1 for me....I think next year I will actually play with rear alignment more....

Actually curious question, what did the car weighed in in the end in race trim? Mine never seen a set of scales yet....

3098 lbs with 2 gallons of gas and the stock exhaust.

Congrats on a strong finish! I didn’t realize you guys were running a CTR… it’s a fun car for sure and really damn capable.

Locally, our club will allow the vitour p1 for autocross. Any fit the 295s on the factory wheel in street class?

Assuming you're on the stock width wheels, in general, pinching wider tires won't net much performance gain for autocross, and can actually be slower. Today's crop of top tier autocross tires are very sensitive to wheel width. I think 295's would be in that direction...too much tire for the 9.5" wheels. But the only way to say for sure is back to back testing.

I tried 295s on front with the RE71RS. They worked good for heat management and for sweeper courses, but felt sloppy for actual slalom intense courses. Very difficult to mount! You get blacklisted by your tire shop

I currently run 275s in front and I am pretty satisfied.

So 295s fit without rubbing , that’s good to know! I’m on 275 stones now too, and want to test the vitours next. Not as stiff as the stones or my tire guy would hate me too lol

295s fit without any rubbing with +53 offset wheels. Not sure about other offsets.

Low 40s. +R mode with long press. I think agile handling assists may have caused the big slide. The understeer was completely my fault. Too hot then tried to brake hard while turning!

[RacingManiac]

still not a 100% sure im going with a CTR but its seems like the right choice... its either that or an SI setup for G-Street
