Shims either side of the top ball joint total three. The width of the top ball joint body, plus 3 shims plus the offset of the arms equal the length of the inner pivot shaft. more shims and you'll be inducing stress to the top arms.
Rear toe.....a debatable subject and a bit involved for this short space. My rear will be set with 1/8" of toe.
It's a topical discussion because the jag is so difficult to change rear toe as it's done with shims under the control arm inner brackets. If it was an easy adjustment folks would try it and test the results.

Can you give me a bit of an idea with measurements...ie if you were to place a spirit level centre to the bottom ball joint what is an ideal measurement to have the centre of the top ball joint back from the centreline.
