If anyone has the roof spoiler and some subwoofers in he trunk....what did u do to stop the rattle?

 

1/2 thick foam weather strip.

No more rattles if anyone ever adds this and a hard pounding sub.

 

Can you going into any further detail with this? I'll interested in doing this.

 

Yes. I put 3m double sided tape on all edges of spoiler, then a 1/2" thick sticky weather strip down the middle in between the 3m strips.
The spoiler sounds horrible when the system is bumping. The rattle in now gone.

 

Definitely. I'll have to do this when I get my car back. Thanks!
