Auto Sport Performance Products (ASPP) was an American automotive company based in Tempe, Arizona. The company specialized in the production of kit cars, particularly replicas of classic sports cars. ASPP acquired its Cobra kit car project from North American Fiberglass, which allowed it to enter the market with established designs.

The company's product line included replicas of the iconic Shelby Cobra, specifically the Street 289, 289 FIA, and 427 models. In addition to these, ASPP also offered two versions of the GT-40, which were built on Pontiac Fiero chassis. These GT-40 replicas were designed to resemble the Mk I and Mk II versions of the original race cars and were available for purchase either as kits or fully assembled vehicles.
