I want to tighten my bumper, do i just ned to remove the back cloth pillars and then the plastic and then just tighten it down?

and What is the little circle piece on the front bumper for?

 

behind the circle piece is the threads to screw in our tow hook. the tow hook is found in the piece of foam above your spare tire in the rear of the vehicle.

if you're tightening the rear bumper, there is no reason to undo any of the inside paneling, all of that stuff is around the sides of the bumper cover, many of which are just clips, there are screws around the hatch closing area, and next to the wheels in the wheel well though, check those i guess.

 

wow i meant i need to tighten my spoiler down, because it is a little rattly when my subs are on and theres a small gap

 

umm, this is actually a DIY for doing the third brake light, but I believe it'll get you to the right place for tightening those bolts.

is your spoiler aftermarket? or the pedistal one? remove the plastic rear pannel on the hatch and check and see if there are screws you can tighten.

 

yeah, that's what the DIY i linked to helps him do. either way, OEM or aftermarket, that DIY gets him to the right place.
