Wilwood Front Dynapro Drag Brake Kit for Ford Mustang (1994–2004), 11.75-Inch Drilled Steel Rotors

The solid steel rotors in this Wilwood Mustang front kit are drilled to reduce rotating weight for drag-racing use. Four-piston Narrow Dynapro calipers mount radially over an 11.75-inch friction ring. Unlike the vented Pro-Street package, this kit uses 0.35-inch unvented rotors and must be selected for the intended competition duty. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.
