Does anybody know the handling characteristics of sway bars for 1/8 scale buggys. I've heard that front sway bars are not needed or if used........smaller ones should be used??? I know that stabilzer bars help for the "roll " of the car on turns, but does having a stiff front one hamper the buggys handling in turns?? Maybe on ruff surfaces?? I would think that the stiffer the better, but maybe thats not the case?? Any comments are much appreciated!!!! Thanks!!
