A sway bar (anti roll bar) connects opposite wheels through a torsion spring, limiting body roll during cornering. A stiffer aftermarket bar dramatically improves handling without compromising ride quality. How do the adjustment positions work? The Front 1 gears,Rear 2 gears settings let you fine tune the front rear roll balance. More stiffness at the front reduces understeer; more at the rear adds rotation. Can I install this with stock suspension? Yes, the RSS Performance Sway Bar works with both stock suspension and aftermarket coilovers. For maximum benefit, pair it with RSS HAD Coilovers. Is professional installation required? Installation is straightforward with basic tools, though professional fitting ensures optimal bushing alignment and torque specs.
