Adjustment for positive Camber?
If you have the correct tools to do an alignment then a machine is not necessary. But your talking some real dough for a Camber / caster gauge, toe plates, bump steer gauge, turn tables, scale plates and platform, laser level. Is it worth inventing in all of this to do your own alignment when a shop will do it for less than 200 bucks? If you can get the suspension halfass setup, driving a few miles down the road to a shop is not going to hurt anything.
