The Wilwood Narrow Superlite 4R rear parking-brake drilled kit for 1958–1964 Olds and Pontiac rear ends upgrades rear braking with FNSL4R four-piston calipers, drilled 12.88-inch rotors, and BP-10 compound pads. Engineered to complement front big brake systems, the kit's internal shoe parking mechanism offers superior static holding power while keeping a tidy installation. Optional caliper finishes and rotor choices let builders match performance and appearance.
