 This success was limited though with only one circuit available.In 1990 the 1/2 mile (805 metre) Speedway Super Bowl at the eastern end of the Bob Jane owned Adelaide International Raceway also saw NASCAR racing, giving the category the chance to run on both a high banked speedway and a traditional flat short track.The slower Super Bowl was a welcome addition to the series as it offered a new challenge with its short straights and much tighter turns which unlike the 24° banking at the Dome that allowed for high speed, was only 7° at AIR.
