Product details

Drilled and slotted 13.50-inch rotors pair with black Superlite 4R calipers in this Nissan rear kit. BP-10 pads are supplied, and the hats work with the original internal parking shoes rather than replacing them with a second caliper. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves 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.
