Product details

A six-piston caliper for the left side, the red Forged Dynapro 6A is offered here in the nominal 0.38-inch rotor-width configuration. Stainless differential bores of 1.62/1.38/1.38 inches establish the piston layout inside the reinforced body. This component comes from Wilwood Engineering, established in 1977 by Bill Wood and based in Camarillo, California. Its disc brake design and manufacturing work includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems.
