Well, the first thing is, you heard the noise, then noticed the drop. Something wasn't seated, or something wasn't tightened. I can't tell you a thing about the suspension as mine is stock and staying that way...but common sense says, something gave in so to speak...if the springs were fine before, they are fine now, but the seating of the pads, would make a difference, not sure what the camber bolts do, but, if not tightened properly, maybe look there..but, I don't think the shocks would have an affect on height...good luck, let us know what you find...
