Are you sure your spring rates are balanced? When the shocks have no oil in them, you should be able to hold both ends of the car down to the ground (table, bench, etc) and let go of each end at the same time. If they are balanced each end will rise at the exact same rate. Do this with all electronics and the battery installed.

The sway bars aren't really going to affect you in this test. It does have an effect on the dampening of each side independently of the other side though which is why I ultimately went back to a higher roll center in the rear but with a lighter sway bar. If you need a swaybar, and you don't always need one, the lightest one you can get away with is going to be best. If I were you, I'd get it setup without the swaybars installed and then later on while fine tuning, add them back in if needed.
