The IMCA Philosophy

IMCA will continue the mission of affordable, entertaining and competitive auto racing as a sanctioning body. We are committed to establishing and enforcing fair and consistent rules that will strengthen and promote the racing industry. Never resting on our laurels, IMCA is driven by past success to achieve future goals

Where IMCA Is Heading

Since exploding onto the racing scene in 1979, the Modifieds have become the calling card of IMCA. These open wheel wonders push the limits of power and excitement. The IMCA Modified was the savior of modern racing, and IMCA has received many awards for its visionary efforts.

IMCA has incorporated that same philosophy in the growth of the seven other divisions it sanctions.

Currently, the RaceSaver IMCA Sprint Car division is America’s fastest growing class of race cars. These fire-breathing winged warriors have helped IMCA return to its roots by making it the largest and most affordable open wheel sprint car division in the country.

The IMCA Story

CarPac (Consolidated American Race Promoters of Automobile Competition) Inc. has been a family owned and oriented business since its founding in 1967. Keith Knaack built the organization around his love for automobile racing, and introduced the Hawkeye Racing News in January of 1967.

Kathy Root joined the staff in September of 1976 as the company’s first full-time employee.

In 1976, Knaack and two partners purchased the bankrupt International Motor Contest Association.

In order to keep production staff year-round, Knaack introduced The Collectors Journal, and the first issue appeared in 1977. In order for Hawkeye Racing News to survive, racing had to survive. And so Keith, along with Larry Sommerfelt of Waterloo, Iowa, developed a set of rules for the IMCA Modified. The IMCA modified was the savior of modern racing, and Knaack has received many awards for his visionary efforts.

Knaack died in June of 1992. On March 1, 1996, Kathy Root purchased the company from the Knaack family.

In November of 2007 the CarPac Publishing division and its’ three niche newspapers, Collectors Journal, Hawkeye Racing News and Barr’s Post Card News were sold to Cass County Publishing.

Kathy’s son, Brett, purchased IMCA on March 25, 2015, from Kathy and his sisters, Debbie Madorin and Jodi Geiger.

IMCA continues its philosophy and focus on family, teamwork and a strong sense of integrity. We remain committed to the mission statement developed in 1992.

IMCA now holds sanctioned events in 36 states and one Canadian province and awards $650,000 in point fund monies to their drivers.
