So I was doing the alignment last night and I have 255/35/18 rear tires with the FFR wheels and the stock donor trailing arms, the right side is fine but left side tire is rubbing the trailing arm, can't see why the left side would be different from the right side, I could just use a 12mm (or so) spacer to solve the problem but I would rather find out why the 2 sides are different, any thoughts ?
