Thanks for the replys. It seems by 1971 all f3 cars (the new ones at least ) had the large sidepods. Did the new f3 1600 require that much more fuel, the race distances didn't increase? One interesting exception seems to be the Lotus 59/69-it buldged only at the drivers area.
Does anyone remember the wording of the deformable structure rule(i know all of our memory's of that time are crystal clear
). Was the deformable structure area an air void of was there some sort of shock absorbing material there?
PS: when did the reg for fuel bags come into effect?
