Yes, it would certainly be a sensitivity thing.Sorry to disagree, but I have personally done that change albeit on a much heavier chassis. Ford Motorhome actually. So many RV owners do it there’s even an acronym. CHF or the ”Cheap Handling Fix”. I will certainly agree there’s a wee difference between the vehicles.
In that case it was noticeable to my passengers as well.
On the other hand, some claim handling benefits using poly bushings rather than rubber; seems like a minor difference in dimensional compression to me, but I have no experience.
I suppose it all depends on how sensitive an individual driver is to vehicle dynamics.
Actually maybe I could buy the notion that moving the pickup point inboard a few inches on an otherwise stiff enough bar making a difference in perceived body roll, especially on very tall vehicles.
As far as that kind of change having an impact on understeer or oversteer and corner handling in general, a few inches on the same bar? Not even close.
On a few of my early race cars we had bars that could be adjusted as much as 18”. The difference between full hard and full soft on one end was always a tweak, never anything that was going to change an under or over steering car back to neutral.
So do I think the few inches of adjustment on the bar in question would make a noticeable difference in perceived roll stiffness on one of these trucks. I am afraid it would stay in the placebo category for my opinion. I guarantee you it would not change a lap time on any road course I have ever driven on.
