What is this?

toolband66 · 05-26-2022, 10:38 AM

Hey all, maybe someone knows. I haven't had time to really take a look because I was in a rush but after coming out from the store I noticed this hanging. Is this normal? Anyone know what it is? Have my break in service scheduled for next week. A 22' M3 manual

It's hard to see form the picture, is there any way of taking a slightly better one?

Absolutely. Was in a rush and currently at a choir for my daughter lol. I'll get a clearer photo and update

toolband66 · 05-26-2022, 10:56 AM

Photos. Best I can get currently

I am assuming your referring the the black shark fin thing? Thats is for aero to direct air... While at speed for cooling and or for underbody aerodynamics

Yes that. Never noticed it before. Every vehicle has this sticking out?

Def not every vehicle, but every g80/82, yes. Nice to see on this car actually. Ferrari's and such typically have these types of aero, but not usually on regular vehicles.

They're there to direct small vermin away from the spinning driveshaft.

B2BAUTO · 05-26-2022, 02:50 PM

Great video! Love all the explanation. Makes me wonder if all these bolt on lips and spoilers might actually hurt the airflow and cooling of the vehicle.

If it's from BMW probably zero issues

It's in case someone drives their car into a lake or ocean, those fins can actually help you steer back to land.

bri1042 · 05-27-2022, 02:30 PM

The fins on the bottom of my M2C were constantly in danger of being killed by my dumb hill of a driveway. I had the part numbers saved in case I needed to replace them, but they held up. Thankfully, the fins on my M3 aren't a hill problem.

freshxdough · 05-29-2022, 03:27 PM

It's not hanging. It's designed that way to channel air under the vehicle.

Do you know the part number a piece of mine got scraped of from speed bumps.

Oejsup · 03-09-2024, 09:48 AM

Does anyone know that part number of the rubber air curtain he's talking about. mine got frade need to replace it

jummo · 03-09-2024, 07:58 PM

While I am pleased to report mine have almost survived two winters of the occasional snow berm out of my garage and at the end of the driveway, I am not sure I would spend the money to replace them.
I suspect the car will function well without them, even though they are cool.

Great video and never noticed those fins, so appreciate the post
