In my previous cars I did the felt pad/sticky tape/velcro/zip tie stuff and it worked great. Even if the buzz was barely noticeable, it drove me nuts! Hope my next Boxster doesn't have the issue, but if it does it's an easy fix.
Had a minute so took some pics. Now with that noise gone how do I get rid (reduce) of the wind noise . No really is the wind noise on a 986 mainly coming from the mirrors? Are the 987 ones quieter?
