I will say the noise level is enough that I am removing them in the next week or two for the off-season until June.
The rails alone whistle around 55mph, and putting pads on for the boards shifts that upwards to more 65-70mph.. but the bigger pads produce a low frequency thudding/wind buffering noise at 70-75mph, which is also unpleasant.
Considering how dead silent this car's cabin is on the road at serious highway speeds, the added noise is noticeable and something I won't want to deal with for 9 months of the year if I don't have to. For me this will likely be a summer-only accessory.
I think some 3rd parties like Thule may be making rails now, maybe they are more low-profile or aero?
Thanks for your valuable feedback,... also looking forward to mine... still a couple of months of wait though.
Just a comment about the gps, listing of chargers. I believe there should be an option/filter to change from "sort by distance" to only show chargers along your route.
Have not tried that by myself, but that is how it is working with gas stations on my G20 3series and all other BMWs I know.
