Wilwood GT-Slotted Front Kit with Red AERO6 Calipers for 2005–2014 Ford Mustang Using the Specified BMR Suspension

The red GT version supplies 14-inch rotor rings, aluminum hats and six-piston calipers for the specified BMR-equipped Mustang. Its front brackets and included hydraulic lines are part of a conversion whose suspension interface must be checked as carefully as the brake dimensions. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California. It designs and manufactures disc brake systems and components serving motorsport, street-performance and specialized applications. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines; their individual specifications must be matched to the complete brake system.
