Update: I received another set of plates and installed them over the weekend. So far everything appears to be working as designed. Hope they will stay that way for a while.
GC provided me with great and responsive customer service during this process (Jay and Frankie), but they really need to improve their procurement/manufacturing/shipping process. I was sent two pairs of mismatched Eibach springs in addition to the problems with my camber plates.
I hope they will learn from the hundreds of dollars they spent on overnighting me various parts.
