What alignment specs were they using? Usually if it's lowered and they can't get it in spec it means they're using the stock specs, which are incorrect for radials. You want something more like the skosh chart posted above, say -.5* camber, +3 caster and around 1/8 to 1/16 toe in.
You still may need to install a set of offset UCA bushings though to get both the camber and caster to those specs. Plus, if you lower the car a bunch you'll need larger torsion bars to keep from bottoming the suspension. Most of the stock torsion bars can barely do that at the stock ride height.
