Group A Sports Cars

On introduction in 1964, Group A catered only for closed sports racing cars with their open top counterparts continuing under existing CAMS Appendix C Sports Car regulations.

Vehicles were required to have two seats, two doors, mudguards, and an electrical system with operable lights, horn, and starter.

Initially, mechanical elements under Group A were virtually unrestricted[2] however CAMS announced the introduction of a 5-litre engine capacity limit during 1966.

Some of the Group A Sports Cars that were designed and built in Australia include various, Rennmax's and Kaditcha's, the Elfin ME5 and MS7, the Matich SR3 and SR4, Bap Romano's Romano WE84 Cosworth (which actually started its life as a Kaditcha K583) and Bernie Van Elsen's Chevrolet V8 powered Veskanda C1 driven by John Bowe.

These were joined by various famous international marques including Lola, Lotus, McLaren, Alfa Romeo and Porsche.

The Matich SR4 Repco competed in Australia as a Group A Sports Car in 1969 and 1970
