Technically, with a sway bar connecting the left and right sides of the suspension, it can have a negative impact on ride quality over bumps. The stiffer the sway bar, the more pronounced that effect will be. However, virtually everyone I've spoken to about installing a rear sway bar on a GM A-body says it's one of the best modifications they've done. I think the pros far outweigh the cons. I'm certainly going to be installing the rear sway bar that came with my UMI stage-3 suspension package once my GTO is put back together.
