As I said before, with the 2B camber plates camber and caster are not
independent adustments!  Change one and you change the other also (bad
design IMO!).

This is a good idea, correcting for road crown or any other irregularity in
the specific suspension causing slight pull right or left.  But it must be
done after camber and toe are set correctly and as a result of actual road
testing.

IMO, they're just feeding you a bunch of BS.  If you have a fairly level
garage floor and the interest, you can do a much better job DIY with the
simplest of carpenter tools.  BTDT for years.
