(For the record BMW OEM snow racks don't fit into my Thule bars)
Interesting that the F3x family of cars (i'm fairly sure) use Thule wingbar edge for their OEM bars and carriers so unsure why your experience would differ.

I do think with an x5, the aerodynamics probably changes a lot due to being a bit more upright like you say. This would change where the air goes over the roof a bit causing different results?

I do know where you position the bars can have an effect on the wind noise as well as what bike carriers and orientation of those. The 591s for example in reverse are terrible for it due to the way the mount is built.
