Fairly easy to remove the wing,
- First jack up the car, support on axel stands and remove the wheel
- Remove arch lining
- Unbolt all visible bolts in the wheel arch
- Remove the smaller arch lining near the door hinge
- Remove the side repeater
- Unbolt the bolts that secure the wing to the door sill (May be covered in mud!)
- Unclip the edge of the bumper from the bumper
guide (unscrew the torx screws first) and remove the bolts behind there
- Remove the single bolt in the door jam
- Remove the 3 bolts in the engine bay.
- Get another pair of hands to
help you pull the wing off the car. It's stuck with sealant in a few places so be careful it doesn't ping off and damage the door!
That's it!
