rear wheel alignment help

[cgamaralyo]

i have a rancho quicklift front with 2" spacer in the rear with airlift. I also went with 285/65/18 toyos. I have gone to 4 different alignment shops and they all can not get the rear into spec. They said the camber adjustment is max out. I've researched online and called multiple speciality parts shops for rear alignment kits. I was wondering if anyone knew of a rear camber kit that allows for more adjustment? My tires (rears only) are wearing on the outside after just a month and a half of driving.
