Product details

Red four-piston Superlite calipers and BP-20 pads define the GT version of this Nissan rear brake package. The 13.50-inch slotted discs sit on hats designed around the factory parking shoes, requiring the original parking mechanism to be present and serviceable. Wilwood Engineering, based in Camarillo, California, has designed and manufactured disc brake systems since its founding by Bill Wood in 1977. The range spans 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.
