Do you have toe in at the front?
Yeah I asked the guy when I last got my alignment and he said kingpin angle is calculated by castor and camber, and said its not that accurate.
Its strange the castor is different, you'd have to see other ke70 alignments to see if they get a similar thing. You've lost some castor having 86 tops as you said. I remember hearing word of someone flipping them but it think you have to drill holes.
