Wilwood Plain 10.75-Inch Front Brake & Four-Lug Hub Kit, Red, Ford/Mercury Falcon/Ranchero/Comet/Mustang (1963–1966)

Plain-face 10.75-inch rotors and red Dynalite calipers form this Wilwood front conversion for the stated Ford and Mercury six-cylinder spindle applications. The four-lug replacement hubs and supplied brackets locate the four-piston brake package on the matching original spindle. Hub position and wheel clearance need review because the conversion is not dimensionally identical to the drum assembly it replaces. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

The listed Mustang range is 1964–1966, while Falcon and Comet coverage includes 1963–1966 and Ranchero ends at 1965; retain the exact six-cylinder-spindle restriction in each row. Verify that spindle against DS921 before choosing the four-lug replacement hubs. Wheel position moves outward 0.92 inches on both sides, affecting tire-to-body space independently of brake clearance. Original 14-inch four-lug steel wheels require the supplied spacer, and the clearance drawing includes it installed. Check the complete wheel contact face, stud engagement and spoke profile. Hydraulic lines remain separate, with fittings and travel selected for the vehicle rather than the caliper finish. Finish by confirming pedal travel, master-cylinder displacement and the relationship to the installed rear brakes.

Match the individual model, year, submodel and brake configuration in the fitment table below.
