I think I understand what you're asking.
your logic is sound. (pardon the Spok reference) I think is safe to assume the movement would be less with stiffer bushes.
My understanding is toe in factory setting is catering for a novice driver who appreciates more stable straight line handling characteristics.
personally have two vehicles with HR RTA bushes and both cars run zero toe rear and it drives quite nice on the street.
typical toe out for track with more steering response. Toe in for straight line handling.
I'm running

Regarding alignment settings for stiffer/hardened rear trailing arm bushings on my dc2r.

My current stock alignment is with total rear toe in of 2mm. From what I have gathered this stock alignment is for OEM bushings which are softer.

Comparing the OEM and Hardrace bushings, there is a far smaller gap for movement in the hardrace. And seeing as the nature of the trailing arm returning closer to 0mm when travelling at higher speeds, does that mean that the hardrace bushing wouldn't return as close?

Should I be running less toe in as I have hardrace bushings, which are harder/stiffer in comparison to OEM bushings?

EDIT: Also, a question to all dc2r owners running with HR Rear Trailing arm bushings. What are your wheel alignment settings?

My apologies if I don't make any sense, I just don't want to destroy my new tyres.
