The Group-A MA70 Supra had varying degrees of success in various fields such as Rally and 24HR, but is most known for its participation in the Japanese Touring Car Championship (JTCC). In the JTCC, the Supra did not win as many races as intended, which is primarily judged on the fact it was underdeveloped and its placement in a higher tier division under regulations because of the 3.0-litre engine displacement, imposing the Toyota with the performance inhibition of running with a higher curb weight and less power compared to the rest of its class. Both the TOM'S and SARD teams fared well in results in the (JTCC) with the TOM'S team winning on its debut in 1987, before abruptly ending their (JTCC) career with the MA70 Group-A in 1989.
