And doing armchair suspension engineering.

Just add some increased kinematics for performance

These circles were, in essence, me drawing up something to see if Ford had a reason for doing something fucky while fixing something else fucky that they, themselves, did. White circle/radius is the “neutral” deflection of a two-stage suspension link if deflecting with all motion in the “loose” link and none in the “fixed” one. It’s also the basis of one aftermarket alteration. Purple is the Ford OEM fix - going to a fixed point about in the halfway position of the link - and the green is going to a single point at the bottom of the two-stage link, as provided by Moog and several other aftermarket setups.
The circles on the right were examinations of secondary motion in the more rigid link and its effects on the effective radius of the suspension component. The notes on the three circles to the left are related to the relative position changes without that motion, which would impact camber change under load.
My conclusion - lower is better in terms of camber change under “neutral” load, and the elongation or compression of the two-stage link under cornering would put the wheel in just about the same place as it’s meant to be regardless - in fact, the amount of elongation or compression can easily dwarf the position change from pivot point alteration. What it does under braking was just to instruct myself, since it’s pretty uniformly bad, and I wanted to know *how* bad.
This is what I’d hoped to hear, since my intended change is easier to put in at the lower point, not the midway point, and definitely not the top-most point. The midway point seems to be most likely chosen by Ford for convenience in *their* fix, which is not convenience in mine, and is most likely harder on the suspension bushing.
