Wilwood Front Plain Vented Rotor and Five-Lug Hub Conversion, Black Dynapro 6 Calipers, Mustang II/Pinto/Bobcat (1974–1980)

Black Dynapro six-piston calipers and plain 12.19-inch rotors form this Wilwood Ford/Mercury front conversion. Replacement hubs provide the supported five-lug wheel arrangement on the original disc spindle. This is the six-piston mounting package, distinct from the four-piston Dynalite version with a similar rotor diameter. 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

Confirm the Mustang II, Pinto or Bobcat year row and the original disc-brake spindle against DS644. Drum spindles and four-lug wheel retention are excluded from this selected layout. Check bearings, wheel registration and the stated zero offset change. Choose hydraulic lines separately and verify the actual wheel's barrel and spoke clearance before evaluating pedal travel and brake balance.

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