Wilwood Black Dynapro Low-Profile Four-Piston Brake Caliper for 0.50-Inch-Wide Rotors

This black Wilwood Dynapro Low-Profile caliper combines four equal stainless pistons with a forged housing for tight outboard clearance. The nominal 0.50-inch rotor width and 4812 pad shape identify the smaller swept-area arrangement. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.
