Wilwood Front SRP Rotor and Hub Conversion, Black Dynapro Calipers for Ford/Mercury Spindles, 12.19 Inches

Drilled-and-slotted 12.19-inch rotors accompany black Dynapro calipers in this front hub conversion. The kit supplies the matching radial dimensions while retaining lug-mounted calipers and separate spindle hardware choices. Wilwood Engineering is a Camarillo, California manufacturer founded by Bill Wood in 1977. Disc brake design and manufacturing extend across calipers, brake rotors, master cylinders, valves, fittings and brake lines. Parts for street-performance, specialized applications and motorsport must be selected to meet the requirements of the complete brake system.

Fitment & Compatibility

Identify the spindle and production configuration before following DS1012. Check the three-hole disc-spindle machine work, wheel-pad spacer or shield needs and the caliper-to-wheel profile.

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.

Check how the wheel rests on the hub before evaluating spoke clearance. Part 300-11961 (sold separately) is the specified 6.60-inch-diameter, 0.20-inch-thick steel spacer for overhanging wheel contact surfaces. The separate 300-10716 hub shield is recommended for stamped steel wheels without overhang and measures 6.15 inches by 0.09 inch.

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.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.

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.
