I combined an R56 caliper swap with Performance Friction rotors and Z pads. I also coated the pad carriers for appearance sake. Every millimeter of the rotor's width is swept by the enormous PFC pads. Rear brakes were treated to rotors, pads, coating, and caliper re-fresh also. There's adequate clearance between the caliper and R84 wheel for balance weights. Directional rotor veins keep the pads & caliper from overheating while squeezed in the small wheel.
