All American Grand Touring

All American Grand Touring (AAGT)^[1] is the name of a former classification and set of regulations designated to grand touring cars in sports car racing, competing in the IMSA GT Championship, maintained by IMSA between 1975 and 1989.^[2] These cars were All-American, V8-powered, used a maximum of 5 forward gears, and used a steel tube frame (similar to the type used in the SCCA Trans-Am Series), and were designed to compete against heavyweight European manufacturers and machinery of the time, such as Porsche and BMW, who were dominating the series at the time.^[3]^[4]^[5]
