Anyway, many have argued that they don't do anything, while giving the illusion of helping the roll center by placing the front lower arm downards, but not actually changing the pivot points.
I am still having difficulties picturing this in my head.
Would someone please draw up (or find) diagrams that explain the part where it gives the illusion of helping with roll center by moving the arm down, while not doing anything?
Also, here is how they look on the arm (Moonface sells brand new OEM arms with the bushings in them already, so it seems):


I have a couple of brand new OEM S13 arms that I can take pictures of for comparison, as mine has brand new OEM ball joints on them, thus we should be able to make a valid comparison between these Moonface ball joints versus the OEM ball joints.
