Widest tire In back?

[12lepler]

So I was wondering.. what is the widest wheel and tire combo you can have on the back of a GN with 18 inch wheels and with no frame notching? And as far as that's concerned what mods do the fronts need to fit 18 inch wheels without rubbing? Thanks

So many variables at play its kind of hard to answer that question with out some more background or your car and ultimate goal. Read through some of the stickies up top and check out some other people's combos. Quick answer is probably 18x10 in back with a 305/35 and 18x9.5 in front with a 255/40. Id say thats the biggest with minimal mods like rolling fender lips in back and not having to cut up the front fenders. Joel
