E55_MvP

Hey guys, I'm somewhat new to the forums and I've just had my 2005 E55's frin t passenger side air strut go out on me, which means it's time to install coilovers! Has anyone in the area ever done a coilover install before? I've got the writeup and even bought the same brand as what's in it but it's still a bit daunting. Any help would be greatly appreciated!
