Product details
The 13.38-inch AERO6-DM front brake package uses this GT rotor and integral hat to retain the intended caliper-to-rotor relationship. Its 48-vane iron casting combines a 1.25-inch friction section with a 0.680-inch offset and black electro-coat finish. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.
