The 1mm spacers on the steering spindle allow for an axle height adjustment independent of suspension sag. This can add or take away steering. The height of the steering ball stud should be adjusted the same amount, at the same time as to not disrupt ackerman setting. Raising the spindle (lowering the front of the car) usually results in more aggressive steering. Lowering it (raising the front), usually the opposite.
The ball stud height on the steering block is to adjust roll center. It is generally a smaller adjustment than changing the upper link length. Most cars have a ball stud height adjustment on the inner block, not the caster blocks. The 22 can be adjusted on both/either end of the link.
