IROC VIII
The eighth year of IROC competition took place in 1984. IROC VIII saw the use of the Chevrolet Camaro in all races, and was the first incarnation of the current IROC format in which twelve drivers from different series compete in all four races. Races one and four took place at Michigan International Speedway, while race two took place at Burke Lakefront Airport, and race three ran on the Talladega Superspeedway. Cale Yarborough won one race en route to the championship, and took home $150,000 for his efforts.
