Wilwood Ultralite Brake Rotor, 11.75 x 0.81-inch, 32 Straight Vanes

A plain friction face and 32 straight cooling vanes make this Ultralite rotor an option for a compatible street or moderate-temperature race brake system. Its 0.81-inch width distinguishes it from the thicker rotor sharing the 11.75-inch diameter. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California, where it designs and manufactures disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications; each part must suit the complete brake system.
