The Super GT series, formerly known as the All-Japan Grand Touring Car Championship or JGTC , is a grand touring car race series promoted by the GT-Association (GT-A). Though the JGTC was authorized by the Japan Automobile Federation and recognized by the FIA, the Super GT is authorized directly by FIA.The JGTC?established in 1993 by the JAF (Japanese Automobile Federation) via its subsidiary company the GT-A (GT Association)?replaced the defunct All Japan Sports Prototype Championship for Group C cars that was terminated by the end of 1994 and in the same year Japanese Touring Car Championship for Group A touring cars, which would adopt the supertouring formula which was used worldwide. Seeking to prevent the spiraling budgets and one-team/make domination of both series, JGTC imposed strict limits on power, and heavy weight penalties on race winners in an openly-stated objective to keep on-track action close with an emphasis on keepingthe race goers happy.
