The Sports Car Club of America (SCCA) is a non-profit American automobile club and sanctioning body supporting road racing, rallying, and autocross in the United States. Formed in 1944, it runs many programs for both amateur and professional racers. History The SCCA traces its roots to the Automobile Racing Club of America (not to be confused with the current stock car series of the same name). ARCA was founded in 1933 by brothers Miles and Sam Collier, and dissolved in 1941 at the outbreak of World War II. The SCCA was formed in 1944 as an enthusiast group. The SCCA began sanctioning road racing in 1948 with the inaugural Watkins Glen Grand Prix. Cameron Argetsinger, an SCCA member and local enthusiast who would later become Director of Pro Racing and Executive Director of the SCCA, helped organize the event for the SCCA. In 1951, the SCCA National Sports Car Championship was formed from existing marquee events around the nation, including Watkins Glen, Pebble Beach, and Elkhart Lake. Many early SCCA events were held on disused air force bases, organized with the help of Air Force General Curtis LeMay, a renowned enthusiast of sports car racing. LeMay loaned out facilities of Strategic Air Command bases for the SCCA's use; the SCCA relied heavily on these venues during the early and mid-1950s during the transition from street racing to permanent circuits. By 1962, the SCCA was tasked with managing the U.S. World Sportscar Championship rounds at Daytona, Sebring, Bridgehampton and Watkins Glen. The club was also involved in the Formula 1 U.S. Grand Prix. SCCA Executive Director John Bishop helped to create the United States Road Racing Championship series for Group 7 sports cars to recover races that had been taken by rival USAC Road Racing Championship. Bishop was also instrumental in founding the SCCA Trans-Am Series and the SCCA/CASC Can-Am series. In 1969, tension and infighting over Pro Racing's autonomy caused Bishop to resign and help form the International Motor Sports Association. Sanctioned racing Professional racing The SCCA dropped its amateur policy in 1962 and began sanctioning professional racing. In 1963, the United States Road Racing Championship was formed. In 1966 the Canadian-American Challenge Cup (Can-Am) was created for Group 7 open-top sportscars. The Trans-Am Series for pony cars also began in 1966. Today, Trans-Am uses GT-1 class regulations, giving amateur drivers a chance to race professionally. A professional series for
