C4 caster adjustment? how?
I have a 93 c4.
I can see where shims can be added and removed, at 2 points, on each upper control arm camber, or toe (ie. if you just put put a shim at one point and not the other).
What I cannot see is how you would adjust caster.
Is caster fixed? or adjustable?

You adjust caster by changing the shims on the upper a-arm. By putting more or less on the front or the rear you can move the upper ball joint forward or backwards to change the caster.
The toe is adjusted with the tie rods.
