My comments & posts in this thread are based on the OPs statement that he was raising the rear by 1.7".........& he wanted to know what affect this would have on caster & camber.
Right, so my actual alignment measurements on a 2" raise in rear ride height being a ~.5° loss in caster are meaningless?
By all means, if you have actual measurements to back up your theory, let's see them. But I'm pretty certain your math isn't representative. @Righty 's drawings appear correct and the .3° change is certainly within the margins considering different ride heights and set ups.
Saying the difference is "unmeasurable" certainly flies in the face of everyone that's actually changed the ride height by that much and said that it resulted in noticeably different steering characteristics though. So let's see your evidence, not just your math.
