The cars are based on either Commodore or Falcon production bodyshells, but from there almost every component is modified and some (such as differentials and gearboxes) are identical in all cars in the category. Engines are 5.0 litre V8 with pushrod actuated valves and electronic fuel injection. Both Ford and Holden engines are based on racing engines from their respective US parent companies. Engines are restricted to 7500 rpm, and in this configuration most of the cars put out around 450 kilowatts of power. Basic front suspension configuration is similar to the road cars, whilst rear suspension is a "live axle" design, and spring and damper design is unrestricted. A "control tyre" is supplied to all teams. A standard "aerodynamic package" of spoilers and wings is supplied to the teams, and is tested so the two makes have as similar aerodynamic characteristics as possible.
