Anyone ever remove the rear bumper?

Yeah.. I've removed my rear bumper... it is fairly easy to do. You need to remove the rear and side panels inside your trunk to access the bolts that hold the bumper on. There are 3 on the rear, and 2 on each side. There are two screws in the wheel well... you'll need to jack up the car (and possibly remove your rear wheels) to really get at these screws. Then, ti just comes right off.
 
you dont have to lift the rear. i got to mine just fine when i took off the bumper. be careful when you remove the plastic "plugs" on the rear underside of the bumper
