I see. The devs at pCARS recommend the following settings:

Overall Effects Strength: 100-104
Spring Effect Strength: 0
Damper Effect Strength: 0
Enable Centering Spring: Unchecked. (so it doesn't matter the setting)
Degrees of Rotation: 900 (different steering setups are done per car
within the game)
Allow game to adjust settings: Checked

Once I discussed this with Ade Allen, he made Real Feel plugin fo
rFactor, and he also didn't now that, and since the developers of both,
iRacing and pCARS don't mention this specifically anywhere, I presume that
they don't know too. Centering Spring works even if unchecked. Centering
Spring is a part of FFB, and it works so that if it is more than 100% it is
harder than natural for you to turn wheel away from center, and if it is
below 100% it is easier than natural (or something like that). Anyway, 100%
is the natural strength of FFB forces (this goes for Damper and Spring,
too).
When Centering Spring is checked, it works indepemdetly of FFB. IOW,
this checked Centering Spring ISN'T a part of FFB, but unchecked is a part
of FFB. If you see the description of this (put mouse arrow over the text),
you'll see that by checking it you "enable centering forces in force
feedback games which do not have a centering force". For force feedback
games that do have a centering force you don't have to check this box, and
this slider adjusts this force unchecked. It really is confusing (it was for
me, also), and there is nowhere an closer explaination, and the whole
simcommunity is convinced (just like you) that this slider doesn't work if
unchecked, but this isn't so. For example, iRacing recommends this slider to
be at 100%. Which means that iRacing's FFB works on "Overall", AND
"Centering Spring".
--------------------------------------------------------------------------------

The placement of "Overall" is also interesting. "Overall" shouldn't
do anything, expect what the name suggests, changing the strength of forces,
nothing more. You should adjust that strength per your preference, and there
SHOULDN'T be a recommendation by game developer for this. In a well balanced
system (natural perspective, and FFB working like it is designed to work)
Overall doesn't do anything. I have it at 118%, but if I put it at 100%, or
at 150%, it behaves nearly the same, only the strength changes. But, we see
that game developers actually only work with the Overall, in a mean of
CHANGING FFB. It does have a sense on unbalanced system, where FFB behaves
diferently. And this is the problem of FFB. If unbalanced, it introduces
sinusoides, and by changing the Overall you are actually manipulating the
amplitude of those sinusoides, and thus you are adjusting FFB.
