IMSA
North American auto racing sanctioning body
The International Motor Sports Association (IMSA) is a North American sports car racing sanctioning body based in Daytona Beach, Florida, under the jurisdiction of the ACCUS arm of the FIA. It was started by John Bishop, a former executive director of SCCA (Sports Car Club of America), and his wife Peggy in 1969 with help from Bill France Sr. of NASCAR. Beginning in 2014, IMSA is the sanctioning body of the IMSA SportsCar Championship, the premier series resulting from the merger of Grand-Am Road Racing and the American Le Mans Series. IMSA is owned by NASCAR Holdings, as a subsidiary company with a designated board of directors.
History
John Bishop and SCCA
John Bishop, a Sikorsky employee, first became involved in motorsport in the 1950s when he met Dave Allen, a Sports Car Club of America (SCCA) staff member. Allen offered Bishop a management position on the SCCA Contest Board, which Bishop quickly accepted. Bishop moved to Westport, Connecticut shortly thereafter. Bishop's duties consisted of defining technical rules and general administration of SCCA competition, as well as providing artwork for many of the club's magazines and event programmes. He became well known in the motorsport scene and enjoyed a good relationship with the organization's president and Kimberly-Clark heir, James H. Kimberly.
In 1958, things changed for Bishop as the SCCA experienced internal changes. A new executive director position was created, to which each regional executive reported.

Why this record matters
The subject matters to the general reference register because the source frames it as north American auto racing sanctioning body. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q84065. VIAF identifies the subject as 136200978. The Library of Congress control number is n95018201. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1969, 2014 and 1958.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
