    Wilwood 140-9315-DR Details

    This group of FDLI Pro-Series rear disc kits provides a complete solution for popular muscle car rear axles that require a parking brake. Forged billet Dynalite four piston calipers, 12.19" one-piece drum/rotors, and high friction pads provide optimized and balanced braking for all types of custom performance street/strip and show machines. The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs enable the builder to personalize the style and optimize brake performance for every individual 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.
