From Scarbs Force India Front Corner article:

"It’s probably that FIF1 mount these mount to the upright in a set up called ‘pushrod on upright’ (POU), this helps weight transfer with steering angle in slow corners."

Is this implying that the pushrod is located off center where attached to the hub and when the hub rotates that the ride height will change? Will this feed back into the steering?

that ´s what i think it is it seems quite bizarr to me but altering spring load with steering anle has an to have an impact on force feedback especially at low speed when downforce is diminishing..
It looks like the wheels straight ahead position is giving most spring pretension ..so the car falls or hunts into cornering with the slightest steering input?

Can do the same thing with caster.

I hadn't thought of it by adding an additional link to the upright until recently. Never designed things quite like that. Seems sensible that you'd get some effect since you're now pivoting that pickup point by having it on the upright rather than the fixed LCA / UCA.

Your question has already been answered by scarbs himself. There is a thread debating this same thing, rather read that and add to that than create another one.

of course you can have it quasi neutral positioning the pushrod pickup exactly on the steering axis.
