Roadster kit cars are available for purchase through Factory Five Racing and Speedway Motors. The Factory Five Racing website offers an MK4 Roadster kit, while Speedway Motors sells a 1927 Track-T Roadster. Roadster kit cars are only partially assembled and serve as vehicle rebuilding projects for potential buyers.
The base MK4 Roadster kit from Factory Five Racing comes with the frame, body, suspension, chassis and other premade components, as of April 2015. Major parts necessary for rebuilding include an engine and transmission from a 1987 to 2004 Ford Mustang, drive shaft, brakes and other components.
The Speedway Motors 1927 Track-T Roadster kit features a fiberglass body and the frame plus headlights and front shock mounts. For rebuilding, the website recommends a Chevrolet 60-degree V-6 or a Ford 2300 cubic centimeter engine.
