Product details
Drilled and slotted 12.88-inch rotors distinguish this black Superlite 6R front kit for Nissan 240SX, Skyline and 300ZX applications. BP-10 pads work in radial-mount forged calipers, and the two-piece rotor assemblies retain the existing hubs rather than supplying replacements. 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
Retains the factory front hubs on the specified 1989–1998 Nissan 240SX, 1989–1994 Skyline and 1990–1996 300ZX applications. The hat accepts four- and five-lug 4.50-inch stud patterns; this clearance arrangement does not convert the hub to another wheel pattern. Select the registration adapters and mounting bolts for the particular Nissan upright, following the instructions for the 240SX and Skyline. Trim the dust shield as directed. This 12.88-inch package requires separately purchased vehicle-specific flexlines. The table identifies the ABS and trim restrictions that must also be satisfied. 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.
