Product details
Factory burnishing prepares this right-hand 15-inch GT rotor before installation in the specified brake assembly. The Spec-37 casting retains a 1.25-inch section and twelve-lug drive interface, supported by 72 curved cooling vanes. 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.
