ok so im getting black s style saleen rims....they are 18x9 mustang wheels with a +24 offset...if i dont lower my car do i have to roll my fenders or no? and i was running 17x8 mustang wheels with a +24 offset and had no rubbing so i figure the 18x9's will only add a half inch on each side so it should rub with 255's right? you only roll the back fenders anyway right and i heard its easy....lemme know if anybody has a pic of 17x9 bullits with the +24 offset( 94-04 mustang rims) i wanna see the difference...
