Setting ride height/alignment with no motor

Complete waste of time. The tires won't wear rolling the car around without the engine in it, and the caster, camber and toe all change with the height of the front end. The only thing worth doing is cranking the torsion bar adjusters about half way in so your car doesn't sit down on the bumpstops when you put the engine in it.

Don't believe me? Have your car aligned, then adjust the torsion bars to lower the front end 1/2 an inch, and take it back to the alignment shop. They'll be more than happy to tell you that your caster, camber, and even the toe has changed. All of these items change as the suspension moves through its travel, which is why people talk about camber gain, toe change, bump steer etc. Without the engine, the car will sit several inches higher, making any adjustments pretty much useless unless you already know how to set the alignment at that height so it will be right when it sits back down.

See this article on changes the spindles to the later FMJ units. Nice little analysis on camber gain and toe change.
