Product details
The larger 12.19-inch race-drilled ring maintains a 0.81-inch vented section for the corresponding dirt-racing assembly. Its iron casting is extensively drilled and should be chosen for the approved racing duty, not simply for its lower mass. Camarillo, California is home to Wilwood, founded by Bill Wood in 1977. The company designs and manufactures disc brake systems for motorsport, street performance and specialized applications, supplying rotors, calipers, master cylinders, valves, fittings and lines. Matching the rotor to the complete assembly matters as much as selecting its diameter or surface treatment.
