I just got my body kit in the mail today , its going to get painted in a couple days and can anybody tell me how exactly to put on the side skirts, cause i really dont want to mess it up.

As long as they fit it's easy(make sure they fit before you get them painted). It's easier if you have somone to help you, so that they can hold them to the car while you drill. First they go in with two screws in the front wheel well and two in the back wheel well. My RS had two holes in the front, but none in the back. If you all ready have holes just line up the skirt to the holes and drill a hole them screw them on. If there are no holes already like on the back of mine just hold the skirt to the car and drill two holes, one closer to the top, and one closer to the bottom and use self tapping screws. Where the skirts overlap the door jam just drill four (small) evenly spaced holes and use self tapping screws.
hope this helps
