So to be clear, this is just a concept (and probably not even a new one). But the "CSV" design, if subtly changed, and maybe not even in an outwardly apparent way, might be able to cause a slight draw through the wheel well and the wheel to draw air across the wheel, which obviously helps cool the wheel, and then being that the wheel is a heat sink for the rotor, in turn, cool the rotor.
Turning those spokes into foils (without radically changing their appearance) might do the trick. It would make the wheels directional, but for the right customers, the benefit could be real. (road course guys)
