Product details
The red Dynapro Low-Profile combines four 1.12-inch stainless pistons with the compact 4812 pad profile. It is the nominal 0.81-inch rotor-width version with a 1.98-square-inch effective area. Wilwood Engineering is a Camarillo, California-based designer and manufacturer of disc brake systems, founded by Bill Wood in 1977. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications.
