Wilwood Front Pinto/Mustang II Rotor-Adapter Hub with 1.720-Inch A Reference

A 1.720-inch A reference separates this Pinto/Mustang II adapter hub from other versions with similar wheel flanges. The chosen intermediate plate must place the rotor correctly within the caliper. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.
