Tether Race Car Association of Australia

'M' Class cars are an Australian class that was developed to attract new members with a limited budget. The design rules are simple, the wheels have to be external and rigid (no suspension) and must have a 3.5cc engine without a tuned pipe. Apart from that go your hardest.

With the design and rules going back to basics this class is highly competitive and well supported with almost every member in Australia owning at least one.
