The original head of ÎçÒ¹¸£Àû51xxtv Pro Racing, Jim Kaser oversaw the first ÎçÒ¹¸£Àû51xxtv professional racing series, the United States Road Racing Championship (USRRC). The success of USRRC led Kaser to organize a series initially involving two Canadian races, thus giving birth in 1966 to the Canadian American Challenge Cup, more commonly known as the Can-Am series. Soon after, Kaser’s Pro Racing department introduced America’s longest running road racing series, the Trans-American Sedan Championship, later known as Trans Am.
It was Kaser’s success with these series that resulted in the most significant change ever to the ÎçÒ¹¸£Àû51xxtv. The organization turned from being an amateur’s club to include a professional, international sanctioning body and organizer.
