Product details
Black electro-coat supplies the protective finish on this right-hand 13.06-inch GT ring. Its 1.25-inch Spec-37 section and 48 curved vanes retain the twelve-bolt geometry, with a separately listed casting weight of 13.20 lb. Founded in 1977, Bill Wood’s Wilwood is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street performance and specialized applications. Its range runs from calipers and rotors to master cylinders, valves, fittings and lines. Choosing a rotor involves matching those surrounding components as well as the vehicle’s intended use.
