a lot less expensive. has a vertical surface for a camber gauge, and i'm sure i could get my toe plates to work with them. looking at the 928 units, they allow for camber by putting a rocker under the base of the stand - same could be accomplished by a broomstick, yes? the miata units are on wheels - same could be accomplished by some wheel dollies?
