Don't forget that the face of the rear upright is determined by the bottom rail of the suspension cage, the bottom wishbone and the rear upright it's self. If all these things are even 0.5-1mm out any where the worse case you could end up being 3mm out very easily. With the best will in the world the rear suspension is made from fabricated parts welded together not CNC made and assembled production components.
