This has puzzled me. There are a pair of plastic fairings, mounted low on the nose, in front of each front wheel. They look like an aero device but they simply "dead end" at the plastic deflector directly in front of the wheel which seems to defeat the purpose of any kind of aero function, if indeed one was intended. Does anyone know what these do?

 

If you stick your hand up there you will find a 2" hole up against the dead end. I assume they are to direct the air up into those holes. I don't know what they are for but for now I'm trusting the Porsche engineers and aerodynamic experts. Sorry that's the best I can come up with.

 

From what you both describe it would seem they're trying to create a pressure differential between outside and wherever the 2" hole leads to. So why not just put an open air scoop in that location? Probably because something that simple and efficient would also channel water and other things into the 2" holes.

 

Got me curious and I went out to look at mine in the garage.. I'm not completely sure it is intended to be aerodynamic.. Or that is it's main purpose.

I noticed when looking at it from the front of the car, the bottom of the "aerodynamic" feature is exactly the same height as something else that extends down aft of it to the left of the front left wheel (still looking from front to wards rear)

I'm almost wondering if it is a scrape guard or something so if you catch a low curb that is lower than your bumper you are warned before you hit the "other thing.." (not sure if it is steering related maybe). I can sort of see what I'm referring to in your pic, but I think your wheels are dangling so it may be a different angle...

Sorry about the other thing description, my floor was dirty and I didn't feel like spending any more time down there or taking pics..

 

I took a look at mine tonight...the answer probably comes from understanding the purpose of the 2" hole at the base of each plastic flare. Also there is a slight angle to them...as if to Chanel air without water or other debri into the hole.

 

I always thought those were brake cooling ducts.
I believe they direct air to an air scoop that cools the brakes.

 

It is there to hold your toast.

 

Yes this could be it.

 

I think you may be right

 

Yes, probably cooling for the front brakes.

But also could be part of the car's ground effects. The underside of the car should not be smooth or flat. Otherwise, it would act as a wing and make the car lighter (and squirelly) at speed. So they design aerodynamic grooves & fairings to disrupt the airflow and do it in such a way as to create negative pressure (or even a vacuum) to offset the car's tendency to lift. Very scientific and these might simply be additional aspects of that.

 

I think you got it.

 

I don't think they are brake ducts as to properly cool the front brakes, they would have piping directly to the hub or more ducts in the wheel well to direct the air.

If you look at the rear brakes there is such a duct to direct air to the brakes.

 

Those are the sand/grit dispenser ports for better grip in snowy/icy conditions. Those Porsche techs thought of every thing!

 

Ditto.
