Wilwood Right Burnished GT Lug-Mount Rotor, 13.06-inch Diameter and 1.25-inch Width

Factory burnishing distinguishes the prepared right-hand version of this 13.06-inch GT ring. The 1.25-inch working section, 8.12-inch register and dynamic mounting lugs must match the same exact carrier geometry as the unburnished option. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility

Match this burnished right rotor to the dedicated twelve-lug carrier with 8.12-inch registration. The 13.06-inch friction ring and 1.25-inch width determine pad coverage and caliper position. Confirm the carrier's retention system rather than adapting a bolted hat of similar dimensions.
