Jay,
Preloaded sway bars and/or panhard rod???? Make
sure all of these are disconnected. Make sure that
both forward rear spring mounts are in correctly. The
bolts that go thru the spring should be up in the
recess. BTDT!! Don't worry so much about the car
setting level but get the weights better. My car sets
low on the left front but the weights are darn near
perfect. Are you using the adjustable spring seats in
the front? Are they allowed?
I've been thru this myself and can't give you a
definite answer. I just kept moving things around
until it all came together. Remember that adjusting
one corner has an effect on the other three not just
the opposite one. Did you notice that you lost 6
pounds total between the two readings??
The next time you go to the scales take some 1"x6"x6"
boards and place varying heights under the wheels as
the car is loaded unto the scales and check your
readings then. Good luck.
