This red 4-piston component is selected by brake-system geometry rather than vehicle year alone. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.\u003c\/p\u003e\u003cp\u003eThe narrow Superlite 4R has four pistons, radial attachment and removable center bridge access to type 7416 pads.
