Wilwood Front Superlite 6R Brake Kit, 13.06-Inch GT-Slotted Rotors and Black Calipers — Ford Mustang (2005–2014)

Black Superlite 6R calipers and 13.06-inch GT rotors form this S197 Mustang front conversion. The package retains the factory hubs and uses radial brackets, with dust-plate clearance assessed during the installation. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together within a properly matched brake system.
