Product details

The red FNSL4R/SRP combination equips the specified Skyline and 300ZX rear hubs with 13.50 x 0.81-inch vented discs. Its aluminum parking-brake hats preserve the factory mechanical parking function, while BP-10 pads serve the four-piston hydraulic calipers. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications.

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.
