Refurbished and painted e31 Brembo aluminum 4-piston calipers with e46 M3 floating rotors and Hawk HPS pads. Bolts right on to the e36 M Roadster/Coupe or M3 wheel carrier. The only problem is that my CSL replicas don't have enough clearance for the outboard side of the calipers. So, I ended up with 18mm of spacers to get enough clearance and the tires now scrub the inner fender wells under hard cornering. Anybody got recommendations for alternative wheels that would get rid of the spacers?
