The M3 is not deafening loud, but the true test for us will be on our trip to Austin on the 14th, where some of the roughest asphalt you can imagine exists. But so far, it's mostly wind noise, not road noise, so I imagine it shouldn't be as loud, but we'll see. Anyway, can anybody post what you're using to seal the windshield to the first roof glass panel, first to second roof panel, and both roof panels to the painted roof 'rails'??? I was thinking of 'siliconing' all of those channels flush with the glass. I think the majority of wind noise is coming from there IMO. I can hear it on the roof rail area, so it could be the top of the windows too, but I'm suspecting the channels between glass and roof rails. I could give a try to those weatherstripping options first... if they're any good. Will also try Wurth rubber care on the gaskets, to see if that makes a difference. The wind noise starts to be noticeable around 60 mph on my car. By 80, it's downright annoying, since I have it right on my left ear. And this is on a 2021, with double-pane front windows, but honestly, it's as noisy as the 2020 we test-drove, by what I remember.
