M Sport body kit - cooling, and what is the black rear bumper supposed to do?
Just wondering, how much more "cooling" does the M Sport bumper provide anyway? Can you measure it or is it just "seems to feel snappier(tm)?" sort of benchmarking? Less frequent limp-modes?
Also, why is the rear M-sport bumper black? |

Doubt the front vents make that much difference, I've heard the US spec ones have two openings as part of a 'hot weather' adaptation feature but I'm in Hong Kong (which gets very damn hot and humid in summer) and we get the grilles with only one side open. Pretty sure MSport for the US market is a purely aesthetic thing.

None. Looks oh so much better though.

The diffuser is completely aesthetic. It has about as much aero functionality as you taping ruler to the trunk lid.

The back of the stock cars don't really have a diffuser. I think we just use that term for lack of better word. The optional M-Performance piece is a real diffuser and to my knowledge, BMW does wind tunnel testing, so it's a functional piece. It actually is designed to reduce drag, but few will notice the difference, I'm sure.

And I doubt the M Performance diffuser is functional...I think for a difuser to be truly functional it has to have a whole sweet of aerodynamic goodies under the car to channel air. You can't just slap part of a bumper on and expect to create any meaningful down force. |

If anyone has info it would be greatly appreciated. |

They can claim that there are aero impacts, but it's nothing to practical effect.

Thank you akuan99. Odd that realoem doesn't seem to list the part(s) nor BMW list the differences but it seems M Sport is more than just a cosmetic package and this makes me quite happy

This one doesn't have track package so I'm not sure if it requres it to have both auxiliary radiators. |

Great... keeping up with the changes year to year alone is a task. I would've thought they'd standardized something like this, additional hardware isn't a trivial detail.
