HwyStarJoe: I think the setup that you have with the 1" front bar should work pretty well. If it is true that a 1 1/8" hollow bar has the same basic roll resistance as a 1" solid, then the system should be very well balanced. With my full Hotchkis setup, the car is very neutral, with a slight understeer depending upon how I enter a turn. It is very controllable, and when exiting a turn I feel very confident with the grip on the rear, it hooks better than I would have thought. To reiterate, I have the front and rear springs, and the front hollow sway bar, no rear bar. I also have the Gulstrand mod, with tubular uppers (and about 6 degress of caster!).
I would try the setup as you have it now, if it is not perfect it will still be close enough to gauge what you should do next. If anything, I would guess that a bit more front bar will be all you'll need.
