I haven't had time for extensive testing yet, but in 2 short trips the whistling has been completely eliminated. Also, the wind noise has been reduced by probably 50%. It's still there unfortunately but is much more tolerable. I will report back if things change.

I appreciate you sharing your “Macgyvering” experiment and sorry it didn’t quite live up to your expectations. I have to say, I could see this on a Subaru Outback, but I really don’t like it on a refined vehicle like the G05. I think BMW really blew it on this and the rear trailer hitch body color fascia.
Even my 4Runner has a dead quiet and more elegant solution for the cross bars and rack system:
I had ordered my X5 with the rack, but cancelling now. I'll wait to see if a better and quieter solution emerges. For those with air suspension and wanting bulk storage like a rocket box, I think a receiver hitch
cargo box would be a decent option.
