I clipped a parking curb in a parking lot and broke the fairing in front of the drivers side front tire. I've got a replacement for the "shark fin" as the BMW guys call it, but was wondering if anyone had any experience removing and replacing this piece. Thank you kindly, Jim

"Shark Fin"?? :huh: Perhaps a picture would be helpful here! :thumbsup:

I'm confused too -- I thought OP was referring to the roof-top fin?

I'll get a pic tomorrow and post it for you. Btw the OEM parts catalog doesn't show it at all.

That would be a great help ... I'm sure you'll get some quick answers. I think you may be referring to a small plastic-sheet piece that is under the frame behind the front wheels ... like a small air deflector. Which, by the way, is exactly the purpose it serves.

Yes but I thought it is like a mini mud flap? So its for deflecting wind?

Well, my camera has got a problem now! Sorry, no pics yet. But, this is the part number and description: Part number 51 71 7 033 753, Cover, bottom, left. It is hard molded black plastic with a molded-in semi-hard rubber fairing (this is what I ripped off)

I see now why they call it a shark fin. Hopefully you've had sucess changing it already.

Part#: 51717033753
Description: Undercar Shield Left Front NOTE: Not for cars with Poor Road Package or M Aerodynamics Package.

Not replaced yet! The screws have been removed, but there are two locking type tabs that are proving to be a real pain. They are about 4 1/2 inches apart and extend up into the center cover. I can get one, or the other, to click free, but not both at the same time. Its a challenge

One of mine are loose, looks like a challenging job.
