Are alignment shims necessary?
Alignment shims are used to correct misaligned components when it’s not necessary or even recommended to replace these components. If your alignment cannot be brought back to spec with alignment shims, you may need to replace other components before your vehicle drives straight and true.
What does alignment shim do?
Shim alignment corrects the vertical position of a movable machine so it will be in alignment with the stationary or reference machine. These shim kits have been in use for decades and are an invaluable tool for the mechanic preforming alignments.
Can you adjust caster with shims?
A safe starting point for caster is 2 to 3 degrees of positive caster. Positive caster is achieved by either adding shims to the rear bolt or removing shims from the front attachment point for the upper control arm. This will probably affect camber, so you will want to check it again after modifying the caster.

What happens if you have too much caster?
Caster settings are not a primary, direct factor in tire wear. However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue. For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings.
