fr. and rr. sway bars

I was thinking about front/rear sway bars also, just as you for street use only. In my "heavy" Ebody, I added a large diameter front sway bar, moved the battery to the trunk (went to a larger battery too for extra weight) and removed power steering from front. Car handles very well, corners nearly flat with little body roll.
At this point the car handles so well I dont see a need for a rear sway bar.
Maybe this approach would work for you.
