TRANS AM 101

SGT Class

A Global Competition

The Super GT (SGT) Class is a collection of high-performance production racecars from around the world. The class pits American powerhouses against European exotics in a contest of global proportions.

From the pure strength of the Dodge Viper to the finesse of the BMW M3, SGT provides an intriguing contest that mixes strategies and approaches of a wide variety of cars.

SGT is intended to be a place for production-based high-performance vehicles with moderate aerodynamic configurations and moderate electronic driver aid capabilities. Sportscars, Grand Touring vehicles, performance coupes and performance sedans, all with their varying engines and drivetrain layouts, can battle on many of the best tracks in America.

Because of Trans Am’s long-time relationship with the Sports Car Club of America, the desire to promote crossover between Trans Am and SCCA Club Racing, as well as the desire to encourage individual ingenuity by allowing teams to develop their own vehicle packages, the SGT rules are closely aligned with the SCCA Club GT2-ST class. Vehicles from the SCCA T1 class may also compete in SGT by reducing weight and engine restrictions. Additionally, vehicles from the equivalent classes in NASA, PCA, BMW CCA, etc. are welcome.

Teams with vehicles homologated to FIA GT4 rules and wanting to further develop the performance of their cars beyond what is allowed in a GT4-based series, may run in a “GT4+” configuration where they remove weight, remove restrictors, and make additional modifications to compete with the other SGT vehicles.

Each track favors certain performance characteristics over others. Therefore, Trans Am balances the performance of the vehicles within its production-based classes with the goal of each vehicle model and performance package having an equal chance to win the championship over the course of the season with equivalent effort and driver skill.
