[1][2] PBR Distributions, along with the TA2 Racing Muscle Car Series, were sold by the category founder, Peter Robinson, to a consortium of regular competitors in 2024.
[3] The cars used in both series series are identical spaceframe chassis[4]built by Howe Racing Enterprises and use a modified GM LS3 engine prepared by McLaren Motor Engineering, a South Australian motor reconditioning and preparation firm (unrelated to the British McLaren Group).
The cars reportedly produce around 100 kg of aerodynamic downforce at the rear,[8] which aids cornering speeds, but is much lower than many sports car classes (a road-registerable Porsche 911 GT3 RS is capable of producing a total of 860 kg of downforce at its top speed[9] The cross-ply tyres are supplied by Hoosier Racing Tire.
[10] Only one type of slick, and one rain tire, are permitted for use, and a limited number of tyres are supplied by the category manager for each race meeting.
ARG is the exclusive Australian licensee of Trans-Am trademarks, and hence is able to use the name in the series they run.
