Product details
This left-hand GT casting provides a 15-inch slotted surface with a 72-vane curved core. The twelve-lug center and 8.12-inch register define its snap-ring installation, while the 1.25-inch friction section fixes the required caliper clearance. Since its founding by Bill Wood in 1977, Wilwood has designed and manufactured disc brake systems from its base in Camarillo, California. Its products span rotors, calipers, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Brake selection should account for the whole installation, including mounting dimensions, friction materials and hydraulic balance.
