Wilwood Drilled/Slotted 14.00-inch Rotors with Black AERO6 — Nissan 240SX (1989–1998), Skyline (1989–1994) and 300ZX (1990–1996) Front Kit

AERO6 six-piston calipers, BP-10 pads and drilled/slotted 14-inch discs make up this Nissan front friction package. The 1.25-inch vented rotors have 72 curved vanes and bolt to aluminum hats, with application-specific brackets positioning the black calipers around them. 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

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.
