Product details
The scalloped 10.50-inch ring is vented through 24 passages while retaining a 0.78-inch working width. Wilwood developed this light Super Alloy configuration for dirt sprint inboard brakes, where the six-hole mounting arrangement and heat demand must match the race system. This component comes from Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with compatibility determined by the complete brake assembly.
