It is a spec series featuring featuring TA2-class cars, and runs as part of the SpeedSeries, a national series of motor racing events organised by Australian Racing Group and sanctioned by the FIA-affiliated Motorsport Australia.

[3] Of the two Australian series using the cars, the National Trans-Am series is generally regarded as having the strongest drivers in recent years, including Nathan Herne and Bathurst 1000-winning co-driver Todd Hazelwood.

Teams and drivers are permitted to alter suspension settings to optimise car setup.
