The Karbonius G8X M2 / M3 / M4 Carbon Front Strut Brace addresses a well-known shortcoming of the G8X M platform: while the F8X M3 and M4 came equipped with a striking and structurally impressive factory carbon fiber strut brace, BMW chose a stamped steel two-piece design for the G8X generation. Karbonius has engineered a complete replacement — a fully autoclave-cured, 100% prepreg carbon fiber one-piece V-brace that eliminates the weak-point joints of multi-piece designs and reduces weight by over 5.5 lbs compared to the factory unit.
Unlike most aftermarket G8X strut braces that rely on multi-piece jointed designs or off-the-shelf carbon tubes inserted into chassis mounts, the Karbonius V-brace is a true monobloc tubular construction. The integrated CNC-machined 6061 aluminum mount provides superior wear resistance and strength at the chassis mounting interface, and is available anodized in natural silver or black. Installation uses factory hardware throughout — no modifications required.
At just 2.2 lbs against the OEM unit's 7.7 lbs, the Karbonius strut brace improves front chassis rigidity while reducing unsprung mass and delivering an engine bay appearance that finally matches the standard set by the factory F8X carbon brace it was inspired by.
