A lot of the "research" which was done in the time was to put foils in "freeflow" air. Why did foils come down... the rules made it compulsory.
Would they have come lower by themselves? Who knows, possibly.
The rules also mandated that they could only be mounted to the chassis, not the suspension uprights too.
Remember that all this was prior to real windtunnel stuff, and much of what was done was often because someone else did it. McLaren wings were tested on a Mini van on an airfield, Jim Halls' Chaparlas had high wings and he had access to more tech stuff than most others.
