Ok, so I just got my system up and running, but now the spoiler rattles like a bitch, as well as the plastic peice behind the license plate on the hatch (its that dark grey piece that goes in). Anyways, how do I take off that plastic piece? I'm gonna tape a bunch of sponge up behind it so it stops that rattle, I'll probably just take the spoiler off and shove some foam behind there as well.

there are 3 phillips head body clips (the expanding prong kind) on the top outside and 2 8mm bolts on the back side... Make sure to remove the plate

And please do not put sponge back there you will trap moisture and eventually start rusting. please do it right.... http://cgi.ebay.com/ebaymotors/100-F...mZ370088819017

this stuff is cheap and that is enough to do your entire car... take out the carpet and do everything you will thank me later

 

As a cheaper alternative, you can get away with that Peal and Seal stuff from Lowes BUT I would NOT do my whole car in it because the asphalt smell can be horrific. I did the floor of my trunk in that stuff and will put some on the back of the license plate. Next it is either Raammat, Dynamat Extreme, Second Skin Damplifier Pro, or Cascade for the trunk lid and doors.

 

i like that stuff in my link... It is great it is thick and butyl so no asphalt smell and freaking kicks *** that on the back of my plate and under the bezel and there is 0 rattles
