Wilwood Black Front Dynapro Kit with 11-Inch Drilled/Slotted Rotors, Ford and Mercury Spindle Applications

This front hub kit combines black four-piston dust-boot calipers with drilled-and-slotted 11-inch rotors. It is selected by the actual Ford/Mercury spindle and production configuration rather than a broad Mustang interchange claim. Wilwood Engineering designs and builds disc brake systems in Camarillo, California. Bill Wood established the company in 1977; it supplies brake rotors, calipers, master cylinders, valves, fittings and lines for specialized applications, street performance and motorsport. The complete brake system determines which individual components are appropriate.

Fitment & Compatibility

Check the applicable three- or four-hole spindle arrangement in DS1011 and plan the specified machine work for disc spindles. The wheel mounting pad also needs the prescribed spacer or hub shield where applicable.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Falcon, Ranchero, Fairlane, Mustang, Torino, Maverick; Mercury Comet, Cyclone, Caliente, Cougar, Montego. Application distinctions include V-8 Spindle Only; Disc Brake V-8 Spindle Only; Drum Brake V-8 Spindle Only; Drum Brake Spindle; Disc Brake Spindle; Drum Brake Front Spindle; Drum Brake Front thru 8/24/69; Disc Brake GT350 & 500 only.

The 1970 Falcon and Maverick drum rows are restricted to production through8/24/1969; the 1970 Mustang disc row is GT 350/GT 500 only. Earlier Falcon, Ranchero, Comet and Cyclone rows retain their V8-only restrictions.

The installation reference distinguishes wheel-pad overhang from a supported stamped steel wheel. Overhang requires a 0.20-inch-thick steel spacer, 6.60 inches in diameter, part 300-11961 (listed in the installation parts list). A stamped wheel without overhang should instead use the separate 0.09-inch-thick, 6.15-inch-diameter shield 300-10716.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Flexline kits: 1965-67 use 220-6471 (18"), 1968-up use 220-9195 (18").

A separately selected master cylinder may require modification of the existing pushrod assembly; it is not supplied in this brake kit.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.
