Well, in five minutes, we will have the Gurney flap on some 1968 obscure car in the Hungarian Can-Am...
Well some of those Porsches ran the "reverse" flap in 68 on their Sports cars
Another addition to the ongoing fetish of running Ti22s because they work better.
Personally I think the only legal bodies for racing should be the ones that actually won some races in the real world during the required time frame (or at least had the decency to have finished the race).
McLarens for everyone!!!
