This red AERO6 package combines six-piston front calipers with 14.00 x 1.25-inch drilled and slotted rotors. The separate hats retain the factory Nissan hub bearings, and the supplied BP-10 pad set fits the AERO6's larger pad envelope. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including 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.
