The Wilwood Narrow Superlite 4R rear disc kit combines forged FNSL4R four-piston calipers with a 12.88in drilled rotor to improve rear braking on popular muscle-car rear axles that require a parking brake. BP-10 compound pads and an internal shoe parking brake provide secure static holding and consistent stopping performance. Optional caliper finishes and rotor designs let builders tailor style alongside function.
