Product details
Red AERO6 calipers and drilled/slotted Spec-37 discs define this 14-inch Skyline R33 kit. The assembly retains the original hub bearings and uses separate aluminum hats, with the included BP-10 pads sized for the AERO6 caliper's broad friction area. 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
Choose this AERO6 arrangement for the listed 1995–1998 Nissan Skyline R33 front hubs and disc spindles. The 14-inch rotors, larger pad footprint and six-piston calipers require clearance checks using the linked drawing. Mount the hats with the specified registration hardware and confirm the existing stud diameter and lug arrangement, particularly on modified hubs. The kit includes braided hydraulic hoses. Dust shields need the instructed trimming, and the final installation must verify caliper centering, hose movement and spoke clearance together. 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.
