The Acuform Muscle Division caters for all types of production-based racing cars. From the venerable HQ Holdens, to V8-powered Ford and Holden Utes, to ex-Commodore Cup cars, Improved Production, Sports Sedans (non-spaceframe) and Japanese Turbos, as well as Classic Touring Cars and more.

The Acuform Muscle Division is one of the most diverse categories around, and the beauty of the racing format is that everyone has a chance of winning. With handicap races, it all comes down to consistency and getting the most out of your machine on the day.
