These were my wheels. I ran them and will vouch for them being straight with no bends, etc. The curbing is maybe two millimeters deep at most and can be quickly sanded with a dremel. I'd have done it if I had time. Just fyi to anyone interested: these will fit all e36s and e46s (not the E46 M3) and are 2-3lbs lighter front to back per wheel than the standard E36 DSIIs and Contours.
