Product Description

The HKS 83001-AT003 Carbon Brace Rear Set is a precision-engineered chassis reinforcement bar developed in partnership with Graphite Design - the industry leader in high-performance carbon fiber shafts. By connecting rear chassis mounting points with a rigid carbon fiber shaft and billet aluminum end brackets, this brace significantly reduces body flex during cornering, resulting in sharper steering response and improved overall handling balance for the A90/A91 GR Supra platform.

Unlike conventional brace designs, HKS incorporated an extra mounting point and a custom inner lid that integrates cleanly with the rear interior. This thoughtful engineering eliminates the aftermarket look common with other braces, making the installation feel like a factory option. Whether you're building a track car or a refined daily driver, this brace delivers a functional and visual upgrade that reflects HKS's commitment to quality and performance.
