Great information on both sites, that's really what I was looking for. Now I'm no longer confused - I know I can't determine what I need.
I didn't realize that what the sway bars are really doing is moving the load between the front wheels and rear wheels, so front sway bar stiffness is dependant upon rear bar stiffness and vise versa.
Also, as Bentwings pointed out, the coil-over spring rate and shock valving are a large factor in roll-resistance and ride. I'm not sure how suited my coil-overs are to my project, I may be in the same boat.
At any rate, I guess I should probably wait on the sway bars until I see how the coil-overs are working.
Thanks for all the help!
