Notes:
This race was originally scheduled for 60 laps with a break in-between but was shortened to 46 laps due to an extra long break. During the first half of the race the teams were having overheating problems due to rubber build up on the grills on the cars. It got so bad that Dave Marcis and other IROC officials were using wire brushes to clean the grills on the cars. They also had to check the water in the radiator of the cars due to the overheating problems. Due to the long break IROC shortened the race to 46 laps. The track had second round qualifying for the NASCAR Winston Cup Series and the NASCAR Busch Grand National race later in the day to get in, forcing IROC to shorten the race.
