yeah the spoiler was a lot of it. i took the carpet off the trunk and none of the bolts were cinched down and 2 were actually missing. replaced the two bolts and tightened and that helped a lot. just went out and got 6 rubber washers to stick in there plus some weather stipping to line certain places with. tryin to do as much as i can with the cheap routes given how much the dynamat stuff is. sounds like somethin inside the wheel well is rattling or it almost sounds like plastic flapping.
