From the above link.

Additionally, a major downforce was noted on the rear axle
compared to the front when the air brake was engaged.

Yep, downforce would be disproportionate.

1955 Mercedes-Benz 300SLR air brakes.




I wonder why they didn't go the more tried and true perforated flaps of US Navy dive bombers in WW2.

..............the split flaps where the flaps work independently are together i.e. the flaps can act as a "normal flap" in that the bottom half drops in the top does not deploy. In a dive bombing situation extend i.e. the top flap goes up the bottom flap goes down and back to his air brakes so that when the airplane is in a vertical dive it doesn't exceed maximum airspeed for the pullout.
