yeah, i'm 335's in the rear. granted it could partially be do with the offset of my rims vs yours but i've got room, only time i've ever rubbed is a right hand turn onto a steep driveway which I account to the fact my rear springs are cut pro-kits. Once I get stiffer rears or coilovers, I can't see that being too much of an issue.
At first i didnt like the wheels and now that i see them on your car, they look great!! Does need a wider wheel in rear to fix the stretched look or you can drop a lil more to give it the hella flush look lol
