The Karbonius G90 / G99 M5 Carbon Fiber Strut Brace Set is engineered to enhance chassis rigidity while reducing weight, delivering sharper handling and improved front-end stability. Designed and manufactured in Spain, this system combines premium carbon fiber construction with precision aluminum hardware for a refined balance of strength, weight savings, and durability.
Developed specifically for the latest BMW M5 platform, this strut brace set significantly improves structural rigidity across the front suspension points. By replacing the heavier factory brace with a lightweight carbon fiber solution, the system reduces unnecessary mass while maintaining optimal strength. The factory BMW brace weighs approximately 1.68 lbs, while the Karbonius version weighs just 0.58 lbs, resulting in meaningful weight reduction without compromising performance.
Finished in a high-quality 2x2 carbon fiber weave, the Karbonius strut brace is available in both gloss and matte options to complement a wide range of engine bay aesthetics. Designed for precise fitment, this system integrates seamlessly with factory mounting points for a clean, OEM+ installation.
