Here is a link to the install video USR put up here in the States.
I've had mine installed for a week and think they're great. My only advice is to remove the plastic wheel well/fender liners before you start. It makes removal and installation installation much easier, especially if you have a long shank T30 torx driver. In addition to the tools listed in the video you will need a 10mm socket and an upholstery removal tool (for the push pin clips on the underside of the fender/spoiler).
Good luck guys. You're really going to like these.
