FITMENT NOTE: Many version of the US spec Sonata/Optima have a carbon canister blocking the area between mounting points on this brace! Please check under your vehicle to confirm that the canister is not in between mounting points or it will need to be removed/moved for installation. This can be found directly above your rear sway bar looking underneath your vehicle.
The Ultra Racing Rear Lower Bar is designed to reduce the flex of the vehicle chassis where it is connected by the lower wishbone of the suspension system. Doing this will lessen the distortion of the vehicle lower suspension when it is under load, especially during hard cornering. It is installed at the lower mounting points between the left and right suspension and the vehicle chassis. Tremendously improving the stiffness at the area where the lower arm is connected to the vehicle chassis. The Rear Lower Bar also keeps the camber accurate during hard cornering.
