If you ask me, BMW eliminated the cooling to reduce air turbulence in the wheel MPG thing. BMW has been big about wheel area turbulence which explains the slots on the sides of the 1M bumper.

BMW probably thought better air flow management in the wheel wells is better than the limited effect of the brake ducts.
