The RPA sway bars are is designed specifically to reduce sway (or body roll) and stabilize the Genesis Coupe when under lateral forces--or in other words, fun, aggressive cornering that we all enjoy. The front bar is 29mm thick and the rear is 25mm.
Sway bars dramatically improve the grip, handling and performance of your vehicle. Cornering loads are spread more evenly across the tires, delivering more grip to the road. You also get improved tire wear as your wheel remain more flat against the road and more upright--and overall ride comfort as a result of less movement inside the vehicle.
