Any intelligence on brake ducting? The past two generations have had them blocked - as in the case of my E90 where the underbody trim even eliminates them. I can't see from any of the undercar photos any plastic pieces or spoilers that direct air to the brakes, a la Porsche. It would be a nice feature for brake pad life on-track.
