Hi guys new here.
I've got a 2006 E53 3.0D Le Mans Edition and some BC Coilovers, just looking for some information with regards to fitting these. Ideally looking for someone that has already done this modification.
I have tried searching on here already

Its quite a straight forward job, the biggest issue was some of the bolts on the existing struts and arms were rusted solid even after soaking them for a day they would not come off. Ended up having to heating them up to get them off without the worry of snapping them.
You will need to strip some of the rear boot panels to get to the fittings for the rears but apart from that approach it like changing a normal suspension set up (make sure you disconnect the battery before starting!).
I didn't cut all the plastic/ rubber pipe work, just folded and cable tied it and hid it behind any splash guards and panels I could find so if I ever sell the car and the next owner is a complete fruit loop and want to go back to air suspension they can.
The BC kit is what I bought, great kit, and quality. The set up it comes set at is lower than standard but not too low, and the ride is firmer without braking your teeth. If you want to get the set up right for your taste, DON'T put all the boot trims back in as you wont be able to get to the settings - a mistake I made! Get it set up the way you like it then put all the panels back in. Once you are happy make sure you get it aligned/ tracked.
Should have fitted it years ago rather than throwing constant money at the evil that is 'X5 Air Suspension'!
