what would happen if you would put a/2 wing profiles or spoilers on the rim shields:more downforce and drag

They are not allowed by the regulations. It would, if they were allowed.

guess how i got the idea from, a fan in the concession stand

Can I ask how these things are allowed?

Those fins look to be directly attatched to the wheel hub, and you can hardly say they don't contribute to downforce....

What the regulations state is that you cannot have aerodynamic devices on suspension components (I'm guessing wheel hubs don't count). Another regulatory stipulation is no movable aerodynamic pieces (apart from the front wing flaps) so the Brawn ones don't contravene either.

Same rule that allows the rim shield in the first place. They are technically part of the "brake ducts" attached to the upright....The rule basically draw these boxes in the wheel area that defines the "brake duct" zone. Anything within that space(and I believe you can't protrude past the diameter of the tires or something) are supposed to be fair game. Ferrari I believe was the first to put winglet/flip-up on the inboard side of the front wheel, and obviously the first to use the rim shield. This season with the durastic cut and reduce width of rear wing all those flip-up appears to compensate for the loss....

Huh! How do they get away with making the suspension arms aerofoil then?
