OK here are some instructions on how to change the skirts on an R56. The process is almost identical for R50 and R53.

Step 1
Assemble the new skirt if this was not all ready done by supplying dealer.

Skirts as they arrived


Step 2
Undo the plastic screws under the car existing skirt. (jacking the car makes access easier). Remove the metal screw at the rear end of the skirt, im pretty sure it was a T10 or T15 screw head.


Step 3
Pull back door seal


Step 4
Dont be afraid here when it sounds like you are destroying the car. You have to be a bit rough. The clips that hold the skirt on are designed to break. Grab the rear end of the skirt and start pulling it away from the car.

You then need to lift the skirt up and away from the car. This will release the clips which are under the chrome finishing strip. Easier if 2 persons do this.

Step 5
Remove the broken clips from the cars body


Step 6
put the new clips onto the new skirt paying attention as to which colour of clip goes where and which way round they are facing.


Step 7
offer the skirt up to the car and start pushing the skirt onto the car from the rear working towards the front.

Step 8
Put the new clips onto the top surface of the skirt


Step 9
Put the screws back on underneath the car

Step 10
Put on finishing strip and re-sit door seal
