Wilwood 14.00-inch GT Slotted Brake Kit — Red AERO6 for Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996), Front

Red AERO6 calipers and BP-20 pads distinguish this 14-inch GT front kit for the specified Nissan applications. Its directional vented rotors mount through short-offset aluminum hats; use the vehicle-specific registration hardware and verify the complete caliper envelope inside the wheel. 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

The AERO6 brackets and two-piece rotors are intended for the listed Nissan factory front assemblies: 1989–1998 240SX, 1989–1994 Skyline and 1990–1996 300ZX. Keep the original hubs and match the hat's four-/five-lug clearance holes and registration adapter to them. The six-piston caliper and 14-inch rotor must clear the wheel spokes as well as the barrel. Consult the application table for ABS and trim details, then follow the guide's vehicle-specific fastener selection and dust-shield modification. Supply compatible brake flexlines separately and check their routing through steering and suspension travel. 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.
