     A  A the correct camber with half a tank in the car.
     A  A My lower A-arms are virtually level to the ground, I've dropped

     A  A about 1/2" from where it was.A  I couldn't lower it any more
     before as
     A  A the alignment shop had to remove all shims from the lower A-am
     to frame
     A  A connection except what was needed for rear toe.
     A  A I'm assuming that if I know the angle at which the uppers are
     with the
     A  A lowers level, I could calculate how much to extend the A arm,
     which is
     A  A at x degrees above the horizontal plane, to push the top of the
     rear
     A  A tire out Y inches to achieve approximately the right camber.A
     Then when
     A  A I take the stock A arms off the car, measure center of the buss
     at the
     A  A frame to the center of the shaft that connects to the upright,
     I'll
     A  A know how much to increase that dimension to get close enough to
     the
     A  A desired camber that the alignment shop can fix the rest with
     shims at
     A  A the lower A arm-to-frame mounting points, including for proper
     toe.
     A  A I've seen the diagrams of Dallara's suspension design, but does
     someone
