Last time I had an alignment done I was able to watch the tech do the work and it did seem a bit tricky to reach in over the tires and make the adjustments. I wonder if putting jack stands under the lower control arms would do the trick and then just use steel rims without tires to set caster and camber? My thought is that with a stock suspension I would want be trying to get the most positive caster and as much negative camber as I could get which based on my last alignment is about 0 degrees for each.
I wouldn't do that at all. Ride height and settled suspension is very important for doing it correctly. You'd need turn plates or at least some steel plates with grease in between them to do the caster correctly as well.
I have 7 deg positive caster and -3/4 deg camber with hotchkis UCAs. It's a good street setup. also 1/16" per side to in.
