Product details
The ULHD sixteen-vane casting uses a 0.99-inch section with smooth pad-contact faces. This right-hand 11.75-inch rotor is intended for matching moderate-temperature dirt or asphalt racing systems, where the thermal duty must suit the lightweight ring. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers and brake rotors work alongside its master cylinders, valves, fittings and brake lines, with each individual component selected according to the complete system's requirements.

Fitment & Compatibility
