TA2 Racing Muscle Car Series

The TA2 Racing Muscle Car Series is an Australian motor racing category using TA2 class cars most closely associated with the American Trans-Am Series. It is the featured category at all rounds of the Hi-Tec Oils Super Series, an annual motor racing series held at various tracks in eastern Australia. The category is managed by TA2 Racing Australia, and sanctioned by the Australian Auto Sport Alliance. The category ownership, along with the distribution and parts business, was sold to a group of long-standing series competitors in 2024.

It is one of two Australian national-level racing series featuring TA2-class cars; the other is the Australian National Trans-Am Series. While run independently, both series feature identical cars, and the TA2 series organisers have changed technical regulations to keep cars eligible for both series.
