1990 Australian Manufacturers' Championship

The 1990 Australian Manufacturers' Championship was open to manufacturers of cars complying with CAMS Group 3A Touring car regulations and was contested over a four-round series.

Rounds were run concurrently with those of the 1990 Australian Endurance Championship.

"Australian Motor Racing Year, 1990/91" suggests that the championship win was tied between Ford & Holden however both the CAMS Manual of Motor Sport (post 1990 editions) and www.camsmanual.com.au state that the title was awarded solely to the Ford Motor Company of Australia.
