Wilwood Front GT-Slotted Brake and Hub Package, Red Six-Piston Superlite Calipers, Selected Full-Size Ford/Edsel/Mercury Models (1957–1968)

The red-caliper GT version uses separate slotted rotor rings and aluminum hats on the supplied front hubs. It retains the specified full-size factory drum spindles and provides the brake mounting components and BP-10 pads for the complete matched front conversion. Wilwood Engineering designs and manufactures disc brake systems and components in a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977, and it is based in Camarillo, California. The range serves motorsport, street-performance and specialized applications, with component choice governed by the complete system's requirements.

Fitment & Compatibility

Verify the exact model/year row and spindle condition rather than assuming that every full-size Ford-family car uses the same bearing journals. Choose the correct dual hub pattern, check +0.03-inch offset and obtain compatible hoses before assembling the brake package.

Separate front flexline references are 220-8307, 220-7699 and 220-12168; select the length and vehicle-end connection appropriate to the chassis. Listed hub offset is +0.03 inch per side.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
