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.
Classes of cars sectioned by the IMCA
- IMCA Modified – Modified race cars with open wheels in the front and closed wheels in the back
- IMCA Latemodel – full-bodied late model race cars
- IMCA RaceSaver Sprint Car – traditional 305 non-winged and winged sprint cars
- IMCA Stockcar – full-bodied production stock cars
- IMCA Hobby Stock – 8-cylinder rear wheel drive entry-level division
- IMCA Northern Sportmod – same as modifieds but with smaller engines and more restrictive rules
- IMCA Southern Sportmod – Similar to Modified but with full GM Metric Frame
- IMCA Sport Compact – 4-cylinder front wheel drive stock cars
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.
