Noise from Coilovers

[Jeffblue]

I purchased BC BR Coilovers and an SPC Rear camber kit.. about 2 weeks after having my coilovers installed, by a professional installer, my right rear suspension started making this really annoying noise. I have no idea what is causing it. I went back to the shop and they made sure everything was tightened down properly and checked everything and still the noise remains. I am very frustrated. The ride is superb, I was very excited about this mod, and here i am 2 weeks later and my car sounds like a rattling POS. Maybe its a bad shock? anyone have any idea what it is? here is a video i uploaded with the sound. its that persistent annoying rattling.
