i totally agree i have an 02 p5 as well and the wing bugs the s*** out of me. after first installing i thought it would be the license plate for sure since it doesn't attach to the body of the car for s***. but holding that down did nothing. i then thought the roof of my car was going to explode until i put my hands on the wing and bam no rattle. please anyone who knows how to get rid of this let me know. i'm going to try to put some dynamat on the piece at the top of the hatch where the hatch and interior meet. we'll see what that does after i get back from my ncaa tournament games in indy tomorrow and saturday. i'll be sure to post if there's any success
