Does Ferrari have the shortest memory on the planet?!
Discussion
Remember all hoo-hah about the 'wheel doughnuts' Ferrari pioneered, and the red team's insistence that they were purely for cooling purposes and had no aerodynamic benefit?
Well, we knew they were lying, but I never thought they'd actually admit it.
This line is in the 599XX press release:
"Ferrari’s engineers have also used F1-derived “doughnuts” which partly cover the brake discs and wheel rim. These have the dual function of improving both aerodynamics and brake cooling."

Warm the brakes?
That's the 1st time I've ever heard of that needing to be done beyond the 1st lap or 2 at the very most.
The covers come off at hot races 'cos with them on the brakes would overheat, true, but they are there for aero efficiency reasons & not for keeping the brakes warm - the brakes manage that all by themselves. Cooling is what brakes need. That's why the cars have brake ducts channelling cold air to them.
The question is not then whether they are aero or no but whether they can be regarded as movable aero. Presumably not as all the teams with the budget for them have them now.

Do you mean the bits which cover the wheel, and get removed when the wheels are changed?
They are there to help warm the brakes, not cool them- in races with extreme brake temperature, they are removed to help cool the brakes

this is brilliant. MrKipling43 said:

Funny looking wheel rim they are covering.

this is brilliant. & yes carbon brakes need air flow, in the same way that the ventilated discs in many performance cars need the same thing. They don't need to be kept warm though.
