Keep us updated on the 17's up front, we're a little worried that wouldn't let as much heat out from the brakes and cause even more brake fade with 2 drivers. How is the clearance with the 245/40? Any issue with the top nut? Have you fitted the rears? I wouldn't have guessed the 40 ratio would fir but if so wow, there's more room then I thought
Good luck this year to all you autocross guys, stay safe
