How'd you determine there is too much camber? As the wheel travels up on compressoin it's suposed to gain camber. I don't know of any adjustment on the rear. If nothings bent and the wheel bearings are alright, stock bushings should fix it.
I do recomend using the dealer for alignment, nobody around here knows there head from camber plate.
