Wilwood Anodized Right Aero6 Caliper, 1.75/1.38/1.38-Inch Bores / 1.25-inch Rotor Width

Wilwood’s right AERO6 with Type III anodizing uses six stainless pistons in 1.75/1.38/1.38-inch bores. The larger differential configuration is paired with type 6617 pads and the 1.25-inch nominal rotor-width body. Bill Wood founded Wilwood Engineering in 1977, and the company is based in Camarillo, California. It designs and manufactures disc brake systems and a component range of calipers, brake rotors, master cylinders, valves, fittings and brake lines serving motorsport, street-performance and specialized installations.
