Wilwood FNSL6R for Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996): Front Brake Package with Drilled/Slotted Rotors, 14.00-inch, Red

Red Superlite 6R calipers and drilled/slotted 14-inch rotors provide the defining hardware in this Nissan front package. The radial brackets and registration rings establish the caliper-to-rotor alignment; a correct hub register and the instructed dust-shield modification are essential to installation. 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

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.
