If the wheel cover is completely covering the rim you obviously get less turbulence out to the sides. Cooling the brakes then becomes a bit more interesting ofc. Having ducts for both intake and exhaust heat.. I doubt it would be a problem to cool the brakes but it would cause some design chances for sure. Another option is to demand the intake to be on the outside.. where the cover is. exhaust then leaving towards the center line.
