I.M.C.A. Modified

Since exploding onto the racing scene in 1979, the IMCA Modifieds have become the calling card of IMCA, thrilling legions of new race fans every year. These high-flying, open-wheel stock cars push the limits of power and excitement on short tracks from coast to coast. Racing in front of millions of spectators each year, IMCA Modifieds have gained a reputation for fierce competitiveness that is as unique as the car itself.
