I am running 18x8 +35 offset, im not slammed up front but I have about 3 fingers thick worth of gap between the wheel and fender vertically and it will rub on a hard bump, but im also running 235 tires and my camber isnt all the way negative. I think if you had coilovers you would be fine with 225s and maybe even 235s if you went as negative as possible on the camber.
