The Wilwood Narrow Superlite 4R rear disc kit pairs forged FNSL4R four-piston calipers with two-piece 12.88-inch rotors and BP-10 compound pads to provide balanced braking for rear axles requiring a parking brake, complementing front big brake upgrades on custom and high-performance street machines. Its concealed internal shoe delivers strong static holding for parking, and optional finishes and rotor styles let builders customize look and function.
