Product details
The left-hand member of this GT pair retains the 1.25-inch friction section and threaded eight-point flange. Spec-37 iron and slotted pad faces form the 12.72-inch ring, which is balanced but not factory burnished. A rotor must suit both the mechanical installation and the rest of the braking system. Wilwood brings that system perspective to its calipers, rotors, master cylinders, valves, fittings and lines, designing and manufacturing disc brake systems for motorsport, street performance and specialized applications. Bill Wood founded the Camarillo, California company in 1977.
