Karbonius G8X M2 / M3 / M4 CSL Carbon Front Strut Brace
The Karbonius G8X M2 / M3 / M4 CSL Carbon Front Strut Brace is engineered to sharpen chassis response and enhance the motorsport character of the G8X M platform while delivering a dramatic reduction in weight over the OEM unit. At just 1.8 kg, it's roughly half the weight of both the OEM standard and OEM CSL strut braces — without compromising the strength or rigidity required of a functional chassis component.
The brace is manufactured in Spain under UNE-EN ISO 9001:2015 quality standards, combining craftsmanship with modern production technology. Each piece is hand-laid with the finest carbon fiber prepreg and completed with critical process steps including 3D scanning, autoclave curing, and robotic cutting for dimensional precision.
Karbonius uses monobloc tubular construction to eliminate unnecessary joints that could become weak points. The lamination schedule combines three different carbon fabrics — including high-modulus unidirectional carbon — while 6061 machined aluminum end components provide superior wear resistance at the chassis mounting points. The result is an OEM-level finish and fitment with a striking motorsport appearance.
