GT slotted rotor faces and red powder-coated calipers identify this 14-inch Superlite front assembly. The vented Spec-37 discs and BP-20 pads are supplied as an axle package, retaining the Nissan hubs and requiring separately selected hoses for the vehicle's hydraulic connections. 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

Use this 14-inch package on the factory disc spindles and hubs specified for Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996). Its larger rotor envelope makes a wheel-template check essential before assembly. The retained hub determines the wheel bolt pattern; align the four- or five-lug hat holes with that hub and fit the correct register adapter. The installation guide distinguishes Nissan mounting-bolt arrangements and requires dust-shield trimming. No flexlines are supplied: choose the correct hose kit for the vehicle. Confirm the individual ABS and submodel restrictions in the table. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
