Product details
Red Superlite calipers and BP-20 pads give this R33 front package its specific caliper and friction configuration. The 12.88-inch GT discs have curved internal vanes, and the supplied line kit completes the flexible connections while leaving the original hubs in place. 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
For the 1995–1998 Nissan Skyline R33 front disc spindle and hub. This is the 12.88-inch Superlite arrangement, so use its own wheel-clearance diagram when checking the installed wheels. Center each hat on the hub with the specified register hardware; modified studs or hubs may require machining. The stainless braided flexlines are included and must be routed clear of the wheel throughout steering and suspension movement. Follow the installation drawing for radial-bracket shims and dust-shield trimming before the final caliper alignment check. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
