Product Description

The Cusco 1H1 492 RE is a bolt-on rear chassis brace built specifically for the GR Corolla's GZEA14H platform, mounting inside the rear bumper cover to tie together factory chassis points and cut down on flex under hard cornering and braking. It's engineered using data pulled directly from Cusco's motorsports research, extending the company's decades of Japanese chassis-tuning expertise to this platform.

Installation is a straightforward bolt-on job at factory mounting points, with no cutting, drilling, or welding required, and the brace works fully on its own. For GR Corolla owners building out a more complete chassis stiffening setup, it's designed to pair with Cusco's Rear Cross Member Brace and Front Cross Member Brace, finished in the same signature blue powder coat for a cohesive look under the car.
