Red FNSL6R Calipers and 12.88-inch Drilled/Slotted Rotors — Wilwood Front Kit for Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996)

Red powder-coated six-piston calipers sit over black-coated SRP rotors in this 12.88-inch Nissan front brake package. The 1.25-inch-thick vented discs use aluminum hats, and BP-10 pads are included; installation also requires the correct vehicle-specific hydraulic hoses. 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

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.
