Product details
Extensive race drilling distinguishes this 0.81-inch Ultralite ring from the street-oriented SRP surface pattern. Its 11.75-inch iron casting uses 32 vanes and is intended for the light-to-moderate dirt-racing duty specified by Wilwood. A rotor must suit both the mechanical installation and the rest of the braking system. Wilwood brings that system perspective to its calipers, rotors, master cylinders, valves, fittings and lines, designing and manufacturing disc brake systems for motorsport, street performance and specialized applications. Bill Wood founded the Camarillo, California company in 1977.
