Junior Sedans (NASR NSW)
This category is the beginner's class - the purpose being to introduce young teenagers (14 to 17 years of age) to the sport in a safe and controlled environment. The vehicles used are your average family small cars (and are not to be manufactured more than 25 years ago) - powered by a Maximum of 1600 cc stock standard 4 cylinder engine. The specifications allow only a very small amount of modifications to the suspension to help with handling, as well as many safety modifications. All cars are fitted with an approved steel roll cage using NASCAR style intrusion bars (as is used in all senior classes).
Toyota Corollas and Ford Lasers seem to be the most common cars currently used.
Average cost $2000 - $5000

Modified Production Sedans (ASCF/Speedway Sedans Australia)
This class is for highly modified 6 cylinder cars (4 cylinder and some rotary powered cars are also allowed). Most of the current cars racing in this class started life as a taxi or maybe your old family sedan. Many use replica fibreglass body panels to reduce weight. Suspension set-ups are modified to suit this type of racing. All race engines must use OEM parts eg. engine block (maximum of 4.5 litre capacity), heads, intake manifold etc. Extensive engine modifications are permitted (refer to Specification book) and with tuning, power outputs of over 380 HP are capable of being achieved. Racing tyres are used on 7 inch wide wheels.
Holden Commodores and Ford Falcons are the most common cars used in this class.
Average cost $10,000 to over $35,000.

Super Sedans (ASCF/ Speedway Sedans Australia)
All Super Sedans use a hand made chassis with an integrated Roll cage. These cars are purpose built race cars using special racing components. Their fibreglass silhouette bodies follow the shapes of production cars, scaled to fit the extra wide and long chassis. They are mainly powered by a large, methanol fuelled, cast iron V8 engine with power outputs capable of 700 HP plus. The most commonly used engines are Chevy but there are a few Ford and Rotary engines racing. They use 12 inch wide racing tyres and wheels to help get all that power to the race track.
The most common body shapes currently used are the Australian Holden Monaro/Commodores and BA/AU falcons, and the American Dodge Intrepid, Pontiac Firebird and Ford Taurus.
Average cost $35,000 to $75,000 plus.
