While it's certainly wise to caution about removing the rear swaybar without stiffer shocks, I'd say that most of us here yanked our rear swaybars off while we still had the stock shocks and never missed it. My wife didn't even notice when I took it off, though the stock shocks were still in decent shape then. My shocks were shot to hell when I upgraded to 20% stiffer Bilsteins last spring, but I had been driving without it for nearly two years and not once did I ever feel like the swaybar needed to go back on.
I've driven with the front swaybar off on my stock shocks and that is a bit too tipsy. I've been toying with removing it now that I've got the 20% stiffer shocks and seeing how it behaves, but I don't think I'll go that way permanently until I finish destroying the swaybar brackets on the front crossmember and have no other choice. :toothless
