On a serious note an upright according to the clever people should have zero kingpin inc. and produce zero scrub
. that leaves just caster for self centering. Well the first two cant be done easily so the whole thing becomes a compromise. From the notes I have been reading if you require 5 deg. of caster you should have double that figure for kpi. So even if someone makes a special upright it will still be a compromise. To achieve any more adjustable parameters other than camber all that is needed is a fully adjustable top wishbone. There are loads of uprights out there that are suitable that tick enough boxes if you do a bit of research.
