Product details
The R33 AERO6 drilled configuration combines black calipers with 14-inch, 72-vane SRP rotors. Its six pistons use 1.75/1.38/1.38-inch bores, and BP-10 pads are included with the brackets, hats and braided front lines. 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
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.
