SG9 STi Wind noise!

Right next thing that's bugging the hell out of me is the wind noise that comes through the door when driving in particular over 50mph.

Ive googled it and seen various complaints and tips to fixing the issue however there are a few different suggestions, now they can't all be the issue surely. The links I've read are a bit dated and was wondering if someone can clear it up.

Which is the be all and end all fix? Who has dealt with the issue, what was your chosen fix and has it worked?

Any links and suggestions are welcome

Thanks
