My E60 had click/clunk when I turned the wheel or went over low speed bumps. It ended up being my top mounts. After looking at your video a few things come to mind. Can you jack up the car and record the video again? Meaning the front wheels off the ground. I would double check the grease on your top mount bearing.
Also was this an issue before or after the coilovers? Another question did a shop install the kit or did you install yourself? How was the top mount torqued?
