The 2 point lower chassis brace stiffens up the chassis by linking the tension arms or toe adjuster brackets of opposing sides. This is usually the place where a large amount of lateral load is transferred due to its proximity to the alignment arms and the tires themselves. By bracing this section of the chassis, a large amount of load can be transferred to a larger area, decreasing the stress to the chassis and its flex points under hard cornering, reducing overall body roll and increasing steering response, feel, and driver feedback.
