I was swapping my tires from the weekend event and noticed that we have brake ducts (from the front air dams). But they are almost "valved" off.
Picture:
Any reason why it's like this? It obviously can be made bigger by taking out that plastic piece, but why did BMW do this?
I'm thinking of just ripping it out, just getting more air flow into there. Anything that would be a negative for this?

That's the way the pork chops on e46 come. Then you remove the punchout.

hm interesting. I saw that we had brake ducts from when my bumper was off. I wonder why they're so tiny at the wheel well too....
if you do it take more pics with the wheels off

They're not brake ducts that will appreciably lower temps at the track. To do that they need to attach to the rotor. What they are good at is cooling the brakes in cool wet weather which makes it feel like there are no brakes at all. Go figure.

In E36M land, the concurrence was that US BMWs get blockoff plates because US drivers don't know to periodically check/clear their brakes in heavy rain to remove the water accumulation on the rotor caused by the open ducts. European cars come with the plate removed.

Awesome setup.What you said. Factory ducts do very little at the track. Thats why I went this route

Hm, so Euro E46s have this plate removed, you think? Maybe we can ask a Euro member on e46fanatics to check for us.
Does that plate just pull out or does it have to be cut?

where is that duct going?
on my e36m i think they were just held in with spring clips, but that was many years ago.
