Wind noise - roof up

[X-S-Z]

I've noticed compared to my last 3.0 roadster that I had for 5 years the ///M roadster has more wind noise at motorway speeds. This is coming from the top-rear of the side windows. Are there any suggestions for solving this? Adjusting / replacing seals etc perhaps?

No experience myself, but I did a search and found this link which might help
