On 1 November 1985 Speedway Park held the first ever Australian Sprintcar Masters to coincide with the running of the first ever Australian Formula One Grand Prix being run on the then new Adelaide Street Circuit. The Masters was won by World of Outlaws driver Randy Kinser of the United States in his JPS-sponsored Gambler Sprintcar from local favourite Bill Barrows. Kinser was in Australia in 1985/86 as part of JPS Team Kinser which consisted of older brother Steve Kinser and cousins Mark and Kelly, with another cousin, Karl, being the crew chief. During the Sprintcar Masters a couple of the visiting Formula One drivers including Renault drivers Derek Warwick and Patrick Tambay were given the chance to do a few 'hot laps' in one of the sprintcars. The governing body of Formula One, the Paris-based FIA, was not impressed, and Warwick received a hefty fine for his laps. Tambay escaped sanction as he had done his laps on the Friday night while Warwick did his laps before the start of Saturday nights action. This actually broke FIA regulations which did not allow a Formula One driver to drive another race car within 24 hours of the start of a Grands Prix without written permission. Among other visitors was triple World Drivers' Champion Jackie Stewart, who reportedly described Sprintcar racing as the "Most exciting form of motorsport in the world".
