Hi guys, so I recently bought a 2012 M5 GT a few months ago, and I noticed that the bottom rail/fender or whatever its called is loose in this particular area. I was told via an M5 facebook group (took with a grain of salt) to get some fender fasteners. Can anybody help me with this issue? Should i use double sided tape instead? I can provide more pics if needed. Thanks.

 

1st, its called a side skirt.

99% chance the retainer clips are broken. You will need to remove the side skirt, R&R the broken clips and re-attach.

 

What he said. IIRC on my Mazda 3 it had both clips and double sided mounting tape.
