Well, the reason I asked about preloading the uppers is that some people still try that as a tool to get the car to leave straignt or not twist up. It may help a little, but all it really does is shift the rear end over in the chassis with a triangulated four link like we have. Shortening up the RH upper control arm really just puts everything in a bind if you have stock or urethane bushings. My uppers and lowers have rod ends front and back (and shperical bearings in the housing) so shortening the RH upper does nothing but shft the rear end over. No preload whatsoever. That is the job of the rear anti sway bar.
I do run at least one full turn of preload with the AS bar though. Nothing else.
