Product details
The AERO6-DM front package for compatible Jeep platforms uses this 13.38-inch GT rotor with an integral hat. Its five-stud layout, 0.720-inch offset and 2.84-inch center register locate the 1.25-inch friction section in the required position. 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.
