SuperPro RC0037RZ-22 Roll Control Sway Bar Kit
A SuperPro Roll Control rear sway bar is the perfect upgrade to improve the stability and cornering feedback of your car. A rear sway bar will reduce body roll in hard cornering and neutralize the factory understeer. Both these effects provide increased tire contact and grip. The sway bar stiffness can be increased by 30-50% over OE sway bars by simply changing the end link position on the sway bar.
