Improved Production cars are defined as 'commercially available touring cars' and are allowed a reasonable level of modification to allow both the racer and the designer room to create an exciting form of race car.
Legal vehicles include rotary screamers, fast fours, turbo terrors, V8 muscle cars from the 1960's through to current models, including front, rear and all-wheel drive. Vehicles must have been sold in Australia or be on a list of limited exceptions.
Improved Production is a popular support category for a number of the V8 Supercar rounds held throughout Australia and the Bathurst 12 Hour Endurance event.
