Yesterday I got my alignment done and when I check my print out I saw something weird. My camber reading where

Front
L -3.0 R -1.7

Rear
L -3.0 R -1.0


The crazy thing about it is the last time I got an alignment, my camber readings where the same (around -1.7 front and -1.0 in the rear) and now two months later one side has crazy camber?!? What do you think is the cause of the change. My suspension setup is Neuspeed sport springs, KYB GR2s, and I have DA knuckles (which were installed before my last alignment). I am also rocking an ebay ball joint kit (w/ there uca). Would that contribute to the change? I also notice one side of my car is lower then the other side (werid with a springs setup). Could my struts be going out? I just need a little assistants on were to look to fix the problem. Could bushing contribute to this? Thanks for your assistance

(I dont want a "get a camber kit response" please. I know I can correct the camber with a kit, but if the camber is changing that much in a short period of time there must be a bigger problem behind it!)
