Recently refreshed 2003 BMW E46 M3 race car for sale.

This car was built to compete in NASA’s GTS-3 class but it can also easily fit in the SCCA’s Super Production or GT2 class. The chassis was seam welded to make this car as stiff as a factory motorsport tub by the NC based race team I-Moto. It is gusseted and reinforced in all crucial points. All body panels (including the roof) have been replaced, except for the quarter panels, with lightweight carbon fiber racing body work. The doors are a composite carbon fiberglass. The front windshield, rear windshield, and rear side windows are all lexan. The splitter, canards, and rear wing are carbon fiber.

A log book can be issued by NASA and the SCCA for this car.
