I have some concerns about adjusting the rear roll center by simply spacing the joint down. The balljoints are mounted at an angle. That means that if you simply space the joint down you end up with a longer lower control arm to put the upright in the same position. Since the rear is a multilink that could affect the camber and toe curves. The affect could, of course potentially be positive or negative, but negative is much more likely. IMO in the rear the way to go is to re-locate the subframe and modify the spindles.
