    Wilwood 140-9219-D Details

    Forged Narrow Superlite 4R rear disc kits provide the ultimate Big Brake solution for popular muscle car rear axles that require a parking brake. FNSL4R four piston calipers, 13" or 14" two-piece rotors, and high performance BP-10 compound pads provide optimized and balanced braking to compliment front big brake upgrades on all types of custom, show and high performance street machines. The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs allow builders to personalize the style and performance for every application.

    Specs

    Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
