Foosh442 Posted November 30, 2011 Posted November 30, 2011 Anybody out there running AIX/ST2 in a S197? Wondering what is the widest tire I could fit under my car ('05 Mustang GT) without doing any major modifications? Currently in AI trim with 275/35-18 on 9.5" wide wheels (44mm offset) and there doesn't seem to be a whole lot more room on the rear. I've done some measuring but curious as to what sizes people are using...thanks. Quote
Knownukes Posted December 5, 2011 Posted December 5, 2011 I am not a AI or AIX racer but I do run a S197 in HPDE. I have the full GRIGGS rear setup and can run 315's on 18" wheels. I run 335's on 20x11.75 wheels on the street. 315's with the GRIGGS is very standard. I know of people going as wide as 335. My car is an 08 GT-500. The are a couple of very long and informative threads on wheel and tire width for the S197 chassis on the Shelby forum in the Super Snake section. BJ Quote
