Founded in 1957, the International Conference of Sports Car Clubs (ICSCC) is the largest sports car racing sanctioning body in the Pacific Northwest of the United States. The organization provides regulatory and administrative support, including guidelines for the administration and rules for competition in organized sports car racing throughout its membership area. Each member club holds one or more racing events each year. The events are run under the umbrella rules provided by ICSCC, with the member clubs providing services at their home track.
