im on bc coils too, when i installed these arms, i decided to go 1/2 inch lower since i did it on a lift, when finished, i was tucking tire completely. the key is to preload the suspension before tightening the bolts. i did this by lowering the lift to where i could use a hydraulic jack to compress the suspension (placed small wooden planks on rotors and compress each side independently). the only issue i find is that when hit a bad pothole, the slide in the adjuster to adjust camber shifts out of place messing up the camber. i was running about -3 camber on both sides but now 0 camber on just passenger side after pothole incident. i torqued it to spc recommendations TWICE!!. it's a real pain in the ***

what bolts are you actually speaking of? anyway, its useless since the problem has been fixed. i purchased a torque wrench and torqued the ball joint adjuster to the recommended 120lb/tq. no problems since!!
