Wilwood Left GT Dynamic Lug-Mount Rotor, Plain-Finish 14.00 x 1.25-inch Spec-37 Iron

This left GT rotor supplies the unburnished fourteen-inch ring for the larger dynamic-lug assembly. Its 72 curved vanes require left-side orientation, while the 1.25-inch section and 8.12-inch register identify the correct caliper and carrier fit. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers and brake rotors work alongside its master cylinders, valves, fittings and brake lines, with each individual component selected according to the complete system's requirements.
