I think I found a way to alter KPI on my car: I can change camber with the extra large excenter bolt on the inner side of the control arm, but also still with the lower strut bolt. If I arrange the strut such that it sits most vertical (less camber with the lower strut bolt), and counter this with making the TCA longer with the inner excenter bolt, I will have effectively reduced KPA and increased the scrub whilst keeping the same camber.
That should yield a little better steering self-centering and straightline stability
