The original design had pivoting flaps at each corner of the body, linked to the suspension in a way intended to react aerodynamically against the chassis' motion over the road surface. Even as the car appeared, however, such devices were banned by the FIA; there was a big back-room drama to get them allowed on the 917 for 1969.
