International Motor Contest Association

The International Motor Contest Association (IMCA) was organized in 1915 by J. Alex Sloan, and is currently the oldest active auto racing sanctioning body in the United States. IMCA is currently headquartered in Vinton, Iowa, and features several classes and divisions of weekly racing in six geographical regions of the United States.

The IMCA championships are held annually at the IMCA Supernationals at Boone Speedway in Boone, Iowa. Another major race is the Harris Clash held at Knoxville Raceway which was developed as a race with somewhat of an emphasis on chassis manufacturers. The IMCA Boone super nationals is the biggest event held by IMCA. It happens once a year around the second week of September. This event has the most IMCA modifieds in one event.

The 1963 and 1964 IMCA champion, driver Dick Hutcherson, was not eligible for the 1965 NASCAR Grand National Series Rookie of the Year, which he won nine times and finished second in the standings; it was given to Sam McQuagg. NASCAR's rookie standards have since changed to being based only on the Sprint Cup Series.
