Wilwood Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996) Brake Kit — Black FNSL6R, Drilled/Slotted 14.00-inch Front Rotors

The black FNSL6R calipers in this Nissan front kit are paired with BP-10 pads and 14.00 x 1.25-inch SRP discs. Drilled and slotted friction faces distinguish this configuration, while the shared four-/five-lug hats require careful matching to the existing hub and wheel. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

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.
