Went to a alignment shop, my rear wheel camper was -2.2 degree, the shop told me that the rear cant be adjusted. Is this true? Anyone have any experience like this? Or we need the SPC Performance Camber Rear Camber Arm in order to adjust the camper on the rear wheel.

I just posted alignment info a few days ago with some pics... I was told rear camber is hard fixed and only toe is adjustable . Mine is a rear wheel drive but you can see my alignment numbers.
