I compressed the spring to take the load off the assembly
and then checked each component both visually and by prying/twisting.
I found nothing that seemed out of the ordinary.
when I put the car on wheels with some wood underneath the spring to simulate a original spring the camber is as specified so
This leads me to believe it is the actual lowering that changes the geometry as opposed to wear and tear.
I going to get a eccentric bolt today and give it a try.
