Just to comment on the earlier posts, they're nothing to do with cooling - they harm the cooling, which is why they've never been used on the front wheels, which obviously carry most of the braking force.
They're purely aerodynamic devices - nothing more.
Same reason why they've been popular in other forms of motorsport (and even non-motorsport) for years now - in all cases the persistent brake temperature isn't as high and poses much less of a problem.
Ferrari have obviously found away around the problem, or are testing solutions.
