It was part of the International Race of Champions series, and served as the season finale each of the six years it was run.

In March 1992, IROC drivers Dave Marcis and Dick Trickle were invited to test at the Speedway.

At the time, the Speedway was considering hosting an IROC event during the month of May, during activities leading up the Indianapolis 500.

The test was considered successful, but several improvements would have to be made to the track before it was safe for modern stock cars to race there.

After the Brickyard 400 was deemed to be a huge success, and since the sufficient track improvements had been made, the Speedway re-opened talks to bring an IROC to Indy.
