FYI-I found some rear links that will drop it a little more than the H&R links. It was years ago so I don't remember the source. With 18mm Velocity spacers I can still get it into proper alignment without any aftermarket suspension additions. Only downside is that they are short enough that when it is jacked up the links can tip to the wrong side which causes a suspension inactive light. Once you are aware no problem to prevent.
