Wheel/Tire fitment to maximize cornering grip
Posted: Wed Oct 12, 2022 12:24 pm
Just looking for some advice on my thoughts for wheel and tire fitment for next season.. I have read the advice on your wheel fitment guide, and I am willing to do some fender rolling.
I have been participating in the 'autocross' program up at lime rock park (the small in-field race track).. This is a less formal format, and the only restriction is that the car needs to be street legal... I've been up against some more exotic cars as a result, but still managed 8th overall fastest time for the season... Goal is to get 1st next year
which I think may be achievable with a super charger installed along with some fatter tires.
My thought is to go with 9 inch wheels, +45mm offset, and a set of 245/40/17 Hoosier A7s. I'm also looking at some offset bushings to give me a couple extra degrees of front camber and allow some extra clearance from the fender.
My other concern, being somewhat new to this whole thing, is whether I am getting to the point where I am putting too much stress on other components with tires this large and grippy.
Any advice? Thanks!

Ohlins w/ street springs (7/4 I think?)
karcepts front+rear
