The
United States Road Racing Championship (USRRC) was created by the
Sports Car Club of America in 1962. It was the first SCCA series for professional racing drivers. SCCA Executive Director John Bishop helped to create the series to recover races that had been taken by rival
USAC Road Racing Championship, a championship that folded after the 1962 season. For its first three seasons, the series featured both open-topped sports cars and GT cars.
Shelby American and
Porsche dominated the Over- and Under-2 Liter classes, respectively. The USRRC ran from 1963 until 1968 when it was abandoned in favor of the more successful
Can-Am series, which was also run by the SCCA.
