Product details
The 11.75-inch version of this Ultralite rotor retains a substantial 1.25-inch friction section within a compact outside diameter. Its right-hand 32-vane core sits behind smooth pad faces, with a listed iron-casting weight of 9.60 lb. 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.
