I have looked it over and even rode in the trunk to help diagnose some rattling coming from the rear end. It turns out that the rear wing is rattling and I think that it is coming from the brake light cover in the rear wing.

I have tried tightened down the four innder bolts that hold down the middle of the wing, but I can't seem to get to the outer 4 bolts that hold down the left and right outer sides of the wing. I think that if I could get the wing off and tighten down the phillips head screws around the LED's in the wing that it might stop the rattling. Anyone else had this problem?
