This 1967 Ford Mustang Fastback was brought to Ringbrothers, a shop specializing in custom billet aluminum and carbon fiber replacement parts for older vehicles. There, it was stripped down completely to the frame, and was sandblasted to get rid of any rust or imperfections.

From there, custom parts were built especially for the car, as well as shaving the drip rails and door handles. The fastback profile was also raised to give the car an overall more hunched, ready-to-fight look.

The trunk and hood are both fully customized carbon fiber panels. The taillight panel was also fully custom built to have a flat profile instead of the concave of the donor car.

The overall length was shortened slightly with new bumper profiles. Underneath, the car gained steel ground effects panels to keep underbody air disturbance to a minimum.

Finally, the engine is a fully built-up Roush 427ci V8, with a Dart Iron Eagle block topped by aluminum cylinder heads. It also has 8 independent throttle bodies feeding a custom electronic fuel injection system, with all the noise going down through a custom, ceramic-coated Magnaflow exhaust.
