History
The BT7 was developed from the BT3, and was the car that really established Brabham as a leading Grand Prix contender. it was a breakthrough season in that Brabham won the International Trophy and Gurney won the French GP. later in the year
Jack Brabham now ran a two-car team from 1963, with a development bringing the first F1 victories for the team, when Brabham won the Aintree 200 and the Silverstone International Trophy in his cars in 1964.Short-stroke Coventry Climax V-8s were used, with five-speed Hewland gearboxes. 
This was built around a stiff space frame but problems came with this suspension and also the fuel system adjustable on board. The suspension was revised, with an upper wishbone and lower transverse link at the rear. the wheelbase was longer and the bodywork more effective after Tauranac had taken aerodynamic advice from Jaguar's Malcolm Saver.  while the Brabham team was third in the Constructors' Championship, ahead of Ferrari. The two cars were modified for 1964 fitted with new wide Dunlop’s.
