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 car bodies are a hybrid of an open wheel car and a stock car. 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.

Sport Modified

A "Sport" Modified division was spun out of this division in the mid 2000s. This class features a similar chassis with lower horsepower, with the claim rule being $550. The division is divided into Northern and Southern Modified classes depending on the track's location in the United States. The Northern Modifieds feature a restricted motor and chassis. The Southern Modifieds are a purpose-built car on a 1978-87 General Motors G-Body chassis.
