Would this be a plausible solution to helping cool the brakes at the track?
After seeing just how hot brakes can really get even on normal cars after a day at the track.. and seeing that it doesn't take high speed driving to do it... a windy country back road could do it... I was wondering..
Would it be possible to turn the rims into, effectively, giant fans? Bear with me.. even if this sounds silly. Take a bunch of fan blades for spokes (just angled flat spokes right?). I mean hell.. you're going to be driving... 99.9% of the time in the forward direction. Wouldn't it be easier than ducting? Just suck air in the sides? Or ... force it out depending on how the spokes get angled.
It wouldn't require any more special considerations than say... directional tires.
Thoughts?

According to Bernoulli's third principle ...
the inversionary turbulence would, in fact, create a diatomic oppository wind tunnelling effect which, in effect would divert the occlusionary vortex force in a positronic trajectory. Therefore, you're f****ng tires would explode.

It has been done before, Actually the Rc wheels made by RPM were modled after the Real thing.
The wheel would help with brakecooling (not much), but the plan was to suck air out from underneath the vehicle - in turn creat down force.

Lots of cars have (had) this
The previous M5, the older Corvette, 90's LS400, TRX BMW Wheels, even the Eclipse had this design but only on one side and the wheels were all right sides (great cost cutting I'm sure).
It has downsides in that moving air with a fan takes HP, though that could result in better braking still.....
I like the looks of the BBS RC and they are light to boot.

The gen-2 BMW M5 rims REALLY had it.
The "fans" were magnesium assemblies that attached to the wheel. They had large, flat blades for moving air. They weren't even a structural part of the wheel; you could remove them to reveal a five-spoke wheel beneath.
I never throught those rims looked good. Because of the gap between the wheel and the "fan" assembly, it looked like the car had whitewall tires.
