School me on drop spindles...

I have a lowered mini truck with drop spindles. The reason for the drop spindles instead of lowering springs was to maintain adjustability of camber and caster. When the front end is lowered the top of the tire likes to lean inwards making a negative camber change. In order to get the camber back into specs you have to remove shims which brings the top of the tire back outwards. The problem you run into is that even if you take out all the shims it still isnt enough. A bodies use eccentric bolts at the upper control arm instead of shims. I am not overly familiar with how much travel they have but the principal I believe is still the same. Depending on what camber / caster values you are trying to achieve you might not have enough adjustment with just lowering the torsion bars.
