 Air flow and the nose of the car



In the picture below where the two red arrows are, Is the area rigth underneath the front of the nose a good place to pick up air or does the design of the nose make it a bad spot for air flow to be picked up from?

exactly , A friends race shop said they would fab up some parts, I was going to have it so I can use the dead rear fog button to actuate them where they open a door and when its real wet out they can be closed, If this is a good location then I will prob do it so I have ram air when I want and also duct it into the break cooling
But before I went any further since most of you guys know this stuff, I wanted to make sure it would be a good place and not a "no air" zone or something

sounds like a cool idea, I don't see why it wouldn't be a good location for airflow.

Off the top of my head, that should be a positive-pressure zone when the car is in motion (at other than low speed). However it will also be a relatively hot air location that close to the road.

Max, knowing you, you don't want to do this to your bumper cover. You can't throw a bumper cover in the street w/o getting arrested.

Seriously, before I did this, I'd just buy a new M bumper cover. Sell your current one w/ the foglights, or stash it away somewhere. Keep the existing cover on the car while you have a body shop integrate foglights into a (not yet painted) M bumper cover.

The existing M brake ducts are ineffective. They basically push air at the tire. For real brake cooling, you have to use real ducted backing plates to get air into the cooling vanes of the rotors. At that point, using the existing bumper cover ducts is just a convenience (and they have to be modified, and you wind up capping the part that goes through the wheel well liner).
