I have 18x8 225/40/18 front - 18x10 275/35/18 rear
New fenders lowered 2" in the front (heidts drop spindles)
New 1/4s 1.5" drop in the rear (hotchkis lowering springs)
Q.A.1 Coil-overs front & rear.
I must be one of the lucky ones because I get no rub in the rear at all
and I rub very slight rub if I pull the wheel all the way to ons side or another. (see old posts for pics)
