The Rouster roadster is an AJ Watson Indy roadster inspired street car. We took the styling and design of the Watson and slightly modified it to make it more street able, allowing more leg room, and a little wider to accommodate 2 people. The chassis is a close version of the Watson, only modifications are larger diameter tube for chassis for street safety, widened 4″ in the front, widened 8″inches in the rear and cock pit area stretched 10″. Other than those slight modifications it is designed, built and set up the same. Torsion suspension front and rear like the originals.sporting a WAC build tube axle in the front, and a Winters quick change rear end in the back. Highly modified French block flat head, with Hilborn EFI powering the car, backed with a T5 transmission.
