Product details
A deeply scalloped outer profile reduces this 11.75-inch Ultralite rotor to a listed 5.40 lb. The 0.81-inch iron ring retains 32 vanes and plain friction faces for the specific light dirt-racing duty identified by Wilwood. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.
