The Wilwood Narrow Superlite 4R rear disc kit uses forged FNSL4R four-piston calipers with a 12.88in drilled rotor and a 2.50in offset stag mount to upgrade rear braking on muscle-car rear axles requiring a parking brake. BP-10 compound pads and a hidden internal shoe give reliable static holding and balanced braking to match front big-brake upgrades while allowing finish and rotor personalization.
