Upon its initial Australian Touring Car Championship (ATCC) debut in 1989, the Group-A Supra failed to finish its first race. With DNF's becoming a regular upset owing to the lack of power and heavy weight of the Supra, it began to strike doubt in the car's capability of success in the (ATCC) which suffered increasingly due to constant rules and regulation changes issuing a red-faced outcome against its main rivals like the Ford Sierra Cosworth RS500, Nissan Skyline HR31 GTS-R and the BMW M3 (E30) which were lighter, more powerful, and had smaller displacement engines. Hopes would further diminish for Toyota in the top division by the introduction of the domineering Nissan Skyline GT-R (R32) in the (JTCC) in 1989 and the Australian Touring Car Championship (ATCC) in 1990. Toyota in 1991 would switch to racing the Corolla Levin instead in the lower tier divisions, while many privateer teams soldiered on with the Supra until the Group A racing's final demise in 1993.
