I see the confusion. On the machine its 0.6 and 4.1
That's different. The right has room for adjustment and the left seems way off.
First thing I would check is the ride hieghts.
Caster will go more positive the lower the ride hieght.
Also unless the machine is set up to show camber in reverse, top of the wheels inward is negative. So have him shoot for .2 to .6 negative. don't need 2 degrees negative unless your running race tires that are calling for that.
