The Karbonius G90 / G99 M5 Carbon Fiber Strut Brace Set is engineered to enhance chassis rigidity while meaningfully reducing weight over the factory unit. Designed and manufactured in Spain under UNE-EN ISO 9001:2015 quality standards, this system combines premium prepreg carbon fiber construction with precision aluminum hardware for a refined balance of structural strength, weight savings, and long-term durability.
Developed specifically for the latest BMW M5 platform, the strut brace set significantly improves structural rigidity across the front suspension mounting points. The factory BMW brace weighs approximately 1.68 lbs; the Karbonius carbon version weighs just 0.58 lbs — a substantial reduction without any sacrifice in rigidity or road feel. The system integrates seamlessly with OEM mounting points for a clean, OEM+ installation requiring no modifications.
Finished in a high-quality 2x2 carbon fiber weave, this strut brace is available in both gloss and matte clear options to complement a wide range of engine bay aesthetics. Each piece is individually numbered to guarantee origin and authenticity.
