Brabham's model for the new 1000cc Formula Three, the BT9, was based closely on the Formula Junior BT6 from 1963. Although not hugely successful, the BT9 paved the way for Brabham domination of F3 through the rest of the 1960's.
The BT9 was very much a Tauranac design with its spaceframe chassis and outboard suspension. The gearbox was a Jack Knight unit based on the Hillman Imp road car, this meant that the rear cross-member was behind the centre-line of the driveshafts.
