Product details
The plain-finish left-hand GT rotor retains a narrow 1.10-inch section for the corresponding 14-inch brake package. Its Spec-37 casting uses 72 curved vanes and an 8.25-inch register within a twelve-hole mounting flange. 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.
