Wilwood Black Front Four-Lug Dynalite Brake Kit for Ford/Mercury Falcon/Ranchero/Comet/Mustang (1963–1966), 10.75-Inch Rotors

This Wilwood front kit converts the specified Ford and Mercury six-cylinder drum-spindle applications to black Dynalite four-piston brakes. Plain 10.75-inch vented rotors mount on replacement four-lug hubs. The six-cylinder spindle requirement matters independently of the model name, and the hub arrangement changes wheel position substantially compared with the original brakes. 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.

• Conditional wheel screening size: 14 inches. Use the installation clearance diagram to verify the actual barrel and spoke profile.
• Wheel-contact support requirement: if the wheel contact surface overhangs the hub face, use the specified 6.60-inch-diameter × 0.20-inch-thick steel spacer between hub and wheel. The spacer is supplied with this kit.
• The original 14-inch four-lug steel wheel requires the supplied wheel spacer for clearance; the wheel drawing includes that spacer installed.

Fitment & Compatibility

Confirm the actual six-cylinder spindle and four-on-four-and-a-half-inch wheel pattern against DS921. The positive 0.92-inch hub offset moves each wheel outward and must be assessed with tire width, backspacing and fender clearance. Some 14-inch wheels may fit, but the caliper outline still needs a spoke and barrel check. Select hydraulic hoses separately and review master-cylinder displacement for the complete brake system.

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