I've recently had some stuff done and required removing the rear fascia, lights, spoilers and all that jazz.

However, after reassembly this time it looks off. I can tell that the center panel with the rings needs some adjustment, but my main concern is the spoiler. It doesn't seem to close perfectly flush with the car anymore. I'm not sure if it is simply perceived to be higher because the other piece is a bit too low, or if the spoiler is off.

Anyone have any suggestions on fitting these parts? Does the spoiler need to be installed with it mechanically set to a different position? In other words, am I doing something wrong during the re-installation other than nuts, bolts, screws, and mechanical bits?
