So I had a chance to get to the alignment shop today, for two reasons. One I wanted to get my setup to RoW and two to see what adjustability was in this stress bar. What I found was this, my stock setup is good but not perfect, it seems that after 92k miles I may need to get into looking for some worn bushings. But I was able to get the proper camber set for initial lapping.
However, what I did find regarding this bar was that simply turning the bar one turn in or out would adjust the toe angle only, one turn IN would change the angle out .10 degrees and turning the bar OUT would result in a .10 degree change in from stock. So no significant camber adjustments, which is kinda what I expected. However after some "spirited" driving after the alignment, I did notice a stiffer feel to the rear.
