The Wilwood Narrow Superlite 4R rear disc kit is a narrow big-brake package built for muscle-car rear axles that require parking-brake function. It pairs forged FNSL4R four-piston calipers with two-piece rotors and BP-10 compound pads for balanced stopping, and a hidden internal shoe provides strong static hold. This red-finished 12.88-inch kit is specified for Big Ford rear axles with a 2.50-inch offset.
