When I listen to music my spoiler rattles. I know you can't fix all noises, but is there anyway to reduce the vibration?

are u talking about the OEM spoiler?
cause mine does that too. its so annoying.
i figured out that it comes from the break light on the spoiler rattling. and i've taken it off and cushioned it. it helped a bit. but the rattling isn't completely gone. still working on it.

is the whole thing hollow? if so your set......

take that sucker off and spray expanding foam all up in there. if you can find out EXACTLY where teh rattle is that will help too.

while your at it, spray that stuff in teh cracks of your trunk lid, that will help too.

then get some weatherstripping and cusion the spoiler down and crank it. that should kill it.

for parts colliding with eachother, making noise, NO deadener works as well as expanding foam. it is teh ultimate cure-all

ok i'm having this same problem. so like what white rabbit said i'm thinking about doin the expanding foam thing. but all i can say is be very careful cause that stuff will warp the spoiler when it expands. what i think i'm gonna do is take the light off. spray some stuff in there. put the light back on real fast and then clamp to boards on either side of the spoiler so the foam can't expand too far. i know this cause my trunk lid has waves in it from the first time i used the stuff. but anyway your not the only one with the porblem and yes it sound like sh it rattling away. so good luck and be careful
