Product Description

The Cusco 566 492 C Power Brace Floor Center is a multi-point, 2-part longitudinal chassis reinforcement brace designed for the 2008-2015 Mitsubishi Lancer Evolution X (CZ4A) and 2009-2015 Lancer Ralliart (CY4A). This brace connects to multiple existing member bolt locations along the center floor tunnel of the chassis, creating a rigid longitudinal link that significantly stiffens the front and middle portion of the unibody structure. The result is a measurable reduction in chassis flex during aggressive cornering, hard braking, and full-throttle AWD acceleration - conditions where the Evo X's high-output 4B11 turbocharged engine and sophisticated AWD system generate forces that can overwhelm the factory chassis rigidity.

The brace features steel oval-section tubular construction with Cusco's signature blue powder-coated finish for corrosion resistance and a clean appearance. Installation is straightforward and uses only existing factory chassis bolt holes, making the upgrade completely reversible with no permanent modification to the vehicle. The bolt-on design connects directly to the member bolts in the floor tunnel area, providing a strong mechanical connection that distributes loads across the chassis structure rather than concentrating them at individual suspension mounting points.

This Floor Center brace is part of Cusco's comprehensive Evo X Power Brace system, which includes the Floor Front (566 492 FF), Floor Rear Side (566 492 FR), Rear Member (566 492 RM), Rear Member Rear (566 492 RR), and Rear Member Side (566 492 RS). For maximum chassis rigidity, Cusco recommends combining multiple Power Braces with their front strut tower bar (566 540 A), lower arm bar (566 477 A), and sway bar kits. Each additional brace builds upon the previous, creating a cumulative stiffening effect that transforms the Evo X's handling precision and driver confidence.
