IMCA Modified

IMCA Modified is the top modified division sanctioned by the International Motor Contest Association. The series began in 1979. It was designed to be a mid-level class between late models and hobby stocks. The first IMCA modified race was held at the Benton County, Iowa Speedway in 1979 on a 1/4 mile track.

The car bodies are hybrids of open wheel cars and stock cars. The front tires have no body around them like an open wheel car, and the back wheels have a body around them like a stock car. The series has a $1,050 engine claim or $100 and exchange rule, and a one tire rule.
