Product details

This black FNSL4R rear package keeps the Nissan Skyline and 300ZX original internal-shoe parking mechanism. BP-20 pads and 13.50-inch GT discs handle service braking, with parking-brake hats integrating the rotor assemblies around the retained mechanism. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

Fitment & Compatibility

For 1989–2002 Nissan Skyline and 1990–1996 Nissan 300ZX rear hubs with the original internal-shoe parking brake. The kit retains that parking-brake mechanism; it does not add separate MC4 calipers. Check the 300ZX trim in the application table and verify the five-lug hub. The dust shield needs trimming. Flexlines are separate, and Wilwood's installation guide and kit listing give different Skyline line-kit references; confirm the correct hose and fittings for the vehicle before ordering. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
