Karbonius G8X M2 / M3 / M4 Carbon Front Strut Brace

Part Number: G8XSB01

While the F8X M3 and M4 received a huge carbon fiber strut brace that was not only incredibly strong, tying the front strut towers to the front core support, but incredibly beautiful as well. Unfortunately, though it was also an extremely functional piece, working with the space and cost constraints, BMW utilized a stamped steel 2-piece strut brace package for G8X cars.

Karbonius has taken it upon themselves to fully redesign the G8x factory front strut brace and replace it with an autoclave cured, 100% Prepreg carbon fiber tubular system, thus reducing the joints and possible weak points. Unlike most other G8x strut braces on the market, the unique 1-piece v-brace doesn't use weaker multi-piece jointed designs or off-the shelf carbon tubes inserted into chassis mounts.

In addition to increasing rigidity, Karbonius has also shaved over 5.5lbs of weight when compared to the factory piece. Besides the performance benefits, the enhanced aesthetic is almost worth it on it's own, it may just rival the beauty of the factory F8x carbon brace.

Karbonius' v-brace bar is complemented with a CNC machined 6061 aluminum mount that is integrated into the bar itself for added strength. We are offering the choice of the aluminum mount anodized in natural silver or black.

Install is quick and easy, utilizing factory hardware. You won't regret this carbon fiber addition to your G8X M3 or M4's engine compartment, especially if you're looking to complement a carbon intake kit or engine cover!
