Product Description

The Cusco 6A1 492 M Front Crossmember Power Brace is engineered to increase chassis stiffness on Subaru WRX STI models from 2015 through 2021. By reinforcing the front crossmember and reducing twisting and bending in the chassis, this power brace helps maintain proper suspension geometry during aggressive cornering and dynamic driving. The result is improved steering precision, reduced body flex, and enhanced overall handling performance under load.

Constructed from high-grade aluminum and finished in Cusco's signature blue, this brace installs directly onto the front crossmember mounting points using the included hardware without major modifications. It works in harmony with other Cusco power braces and chassis bars for a fully integrated chassis reinforcement setup, making it ideal for enthusiasts seeking sharper response and better control on both the street and the track.
