Hi everyone,

I'm interested in buying a wind deflector for my BMW M8 (F91). I've seen both the OEM version and a 3rd party option from Cabrio Supply.

Cabrio Supply Wind Deflector:

• Does anyone have experience with the Cabrio Supply wind deflector?
• How does it compare to the OEM one in terms of performance (wind reduction, noise reduction)?
• Is it worth the price difference (Cabrio Supply: $249 vs. OEM: $744 on sale)?

Part Number Confirmation:

• Is the wind deflector the same for the M8 and the M850/840 models? Sometimes I find used ones for sale but they are advertise for one model or the other.
• For reference, the genuine BMW deflector part number I found is 54-34-7-443-147.

Thanks in advance for your insights!

I have the OEM deflector but just by looking at the exposed hardware on that Cabrio one there ain't no way that is going in my car. I have full leather and one tiny slip the head of the bolts or that weird looking pin would not do nice things to the leather that is all around that area of the car. It also has a funny shape to it in the picture of it up, looks huge. The OEM top you can easily install has rubber ends and plastic. It also can be lifted up or down while driving, not sure about that other one but it looks like it has some sort of thumb screw. Hate to say it but I know the price is steep but I'd go OEM.

For the OEM part; Yes it fits all 8 series convertibles. Deflector Assembly - BMW (54-34-7-443-147) I've seen OEM price at 720 before.

Thanks for the advice! I probably should go with the OEM part. While it's way more expensive, you explained the potential drawbacks of the Cabrio very nicely!

Aosman,
I have a 2020 M8 OEM wind deflector that's never been used. Been sitting inside cover in my garage since car purchase. Used it once for 5 minutes' drive around dealer parking lot, otherwise never touched since. It's yours for free, if you wanna pay for shipping from Houston...
