I would much rather have a teg bumper than a body kit rear (I think it's the combat rear bumper). I'm sure with a little modification, you could get a body shop to put in the bumper for you (and get it painted as well). But I agree with RicoD, if and when you relocate the license plate, it's best if you fill in the trunk area (or get a CF trunk that has that part already shaved).
