I understand what the spacers do. My point is that they shouldn't be necessary. With offset UCA bushings installed it should be fairly easy to get -.5° camber, +3° or more caster, and 1/16" toe in. If it's not, there's something else going on and that should be addressed before spacers are considered.
Stock front wheels. 1" torsion bars. Bilstein shocks. Ride height slightly higher than stock to offset some extra rear height from 1+ springs. All other components stock. Rubber bushings.
The ride height could be the issue. Having the ride height higher than factory has a big effect on the alignment numbers. Your numbers seem pretty off though, so I would still check the offset bushings. But it could be that the ride height is more above the factory setting than you think it is. And that's not a good thing for a bunch of different reasons, so you may want to look into that a little more and consider at least setting the factory height.
