Wilwood Red Six-Piston Front Hub Brake Package with GT-Slotted 14-Inch Rotors for Selected Full-Size Ford/Edsel/Mercury Drum-Spindle Models

The red-caliper GT package supplies two-piece front rotors, aluminum hats and hubs for the specified full-size cars. Its six-piston Superlite calipers are part of a complete matched conversion whose wheel, hydraulic and spindle requirements must be checked together. Based in Camarillo, California, Wilwood Engineering was established by Bill Wood in 1977. It designs and manufactures disc brake systems, calipers, rotors, master cylinders, valves, fittings and brake lines. That range serves motorsport, street-performance and specialized applications; the individual parts must be matched to the requirements of the complete braking assembly.
