Don't see this posted, but have the upper control-arms been removed from the car during the swap?
If not, then there's no way the camber/caster alignment can be off that much, UNLESS there are some obvious differences in the new spindles compared to the old ones.
Are the spindles both symmetrical, besides the side the calipers are mounted?
If not, any chance you got left and right spindles mixed up and the kit was designed for front mounted calipers?
With new/different steering arms, there should only be some toe-in adjustments necessary.
