This reinforcement component minimizes trunk sagging caused by the installation of a GT wing, ensuring downforce is efficiently transferred to the vehicle body.

By reducing trunk flex during high-speed driving, it allows the wing to perform at its full potential while also preventing deformation or paint damage caused by contact with the rear bumper.

It features a bolt-on design that utilizes the factory clip (at the center point), requiring no vehicle modifications. Made from high-strength engineering plastic, it provides solid support for the trunk while minimizing stress on the bumper. A cushioning material is applied to the tip to protect the contact area from damage.

Developed through extensive real-world testing in the All Japan Gymkhana Championship, this reinforcement part combines light weight (approx. 32g) with high rigidity. It is recommended for those looking to maximize their GT wing’s performance or address the issue of trunk sagging.
