i don't do alignments for a living but my buddy lets me use his alignment machine to do alignments on my car.
to the best of my knowledge you have to do a caster swing to get any readings, including camber and toe, from the alignment machine. how were they able to get the other readings without doing a caster swing.
they have a hunter hawkeye machine at the dealer where i work. according to the alignment guy this machine can do alignments on all cars with wheels up to 24" big.
