Wilwood Right Dynapro 6A Black Caliper, 1.10-Inch Rotor Width / 5.06-Sq-In Area

Wilwood’s black right DP6A is the wide rotor-body configuration with a nominal 1.10-inch width. Six stainless pistons use 1.62/1.38/1.38-inch bores in the reinforced forged housing, with type 6712 pads. 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.
