Product details
A polished forged housing carries four equal 1.12-inch stainless pistons in this low-profile Dynapro. The 4812 pad arrangement and nominal 0.81-inch rotor-width channel suit a matched narrow-sweep brake. 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.
