There is already a DIY for the front i know. For the rear -
Remove wheel well from back wheels ( and probalby the wheel)
There are a few screws on the back side of the wheel well
There are 5 clips i think that hold the bumper to the quarter panel. Reach in there and unclip them with a screw driver.
Remove the tail lights.
There are some screws under the taillights
Remove the screws from under the bottom of the bumper
I think thats about all.
