In 1967 as Cooper phased out of racing, they focused more on Formula One teams. This is the only T84, and the last Formula Two car Cooper built.

Gerard Racing took the aerodynamic, slimmer T84 powered it with the 22 BHP Cosworth FVA and entered it in several events, such as Mallory park where John Cardwell finished 13^th, only because he had to stop to change his muddy shoes after lifting the car out of a ditch he had put it in! It was also driven to third place by Peter Gethin at Hockenheim
