ETA: whatever mine is I would like to see how an increase in caster angle improves the weak self centering action, not helped by low gearing on my car. With power assistance steering is over light anyway.
Richard, I know from experience that the rack adjustment is very sensitive and will affect the self-centering. Maybe something to consider.
I find the rack used on two previous Mogs (Jack Knight) self centred much better, had less turns lock to lock and give a tighter turning circle
The current 3.7 is way too slow, despite being PA, and has very little self centering feel
