For autocrossing would it be possible to go to 18x11 square with 315/30/18s? I just have no sense whether this would work? My 18x9.5 WedsSports with 295/30/18 Hoosier has plenty of Room up front. I know some 350z guys run 10.5 wheels square with 315s.
What kind of spacing? Ideas? I'd like to get as much tire and wheel under stock body as possible. I run Coilovers.
I will post picture of my car with 295 up front as it looks to me like I could go a little bigger?
Here is a good shot of my 9.5 front wheels with 285.
