Wilwood Front Red Dynalite Plain-Rotor Kit, Mustang II/Pinto/Bobcat (1974–1980), 12.19-Inch Five-Lug

The red-caliper version of this Wilwood front kit uses plain 12.19-inch vented rotors and five-lug replacement hubs. Four-piston forged Dynalite calipers mount to brackets for the original disc spindle. The package therefore depends on the underlying spindle configuration even where the car already carries modified front 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.

Fitment & Compatibility

Check the vehicle row and the disc-spindle interface in DS614. Confirm the supported wheel bolt circle and register rather than assuming the original wheels carry over. Hydraulic hoses require separate selection and suitable routing at full steering lock. Use the exact wheel-clearance template, inspect rotor centering and evaluate the master-cylinder and pedal arrangement already installed.

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