I plan on keeping the front GS-T(19mm)bar. I want to know if upgrading the rear factory GS-T bar(15mm spring steel) to a 19mm Susp Tech mild steel bar gives better handling/cornering characteristics. I already use poly swaybar bushings so the new set will not help out. I guess it depends if the 19mm mild steel is stronger(less bending) the 15mm spring steel bar. The bends in the bar might be different as well yielding a stiffer bar. Any opinions from those who actually have this rear bar installed.
