M racing & sports racing 1/1/61 up to 31/12/65

The group is intended to cater for racing, sports racing and sports cars with a competition history established in the period between 1 January, 1961 and 31 December, 1965. Such vehicles will reflect the development of more advanced design features such as complex space frame and monocoque structures, sophisticated adjustable suspension systems and the commencement of wide racing tyre development.

Consideration may also be given to the classification within this group of vehicles constructed between 1 January, 1961 and 31 December, 1965 but with a competition history established subsequent to 31 December, 1965 or, in some circumstances, without a racing history, provided the specification of the vehicle is consistent with the general standard of technology evident in vehicles raced during the group period, and the vehicle is compatible in appearance with such vehicles.

Formula Vee vehicles are specifically excluded from this Group.
