my 97 5 door has 17's they are summit like et38 BUT on mine the lip on the rear arch is about an inch thick so coz these wheels where the wrong offset i just attacked that lip with a grinder coz it was a bit too close for comfort oh and lowered -40mm
just a couple of questions!
Do 18" wheels fit fine without any mods ??
Also i've heard from one of my m8's that 40mm lowering is the lowest you need to go if ur only looking to improve the handleing as further than that doesn't make any difference??
