E30 S54 swap AIRBOX made 100% in prepreg carbon fiber in our facilities in Spain under ISO 9001 Management Quality System rules by qualified staff. The BMW M3 E46 CSL it´s one of the most famous and mythical cars in the world, and part of the success is due to the carbon airbox. This intake generates what is probably one of the best noises of any sports car. For that reason, a lot of BMW E30 users want to get the same noise in their E30´s S54 Swap. As the E46 CSL Airbox does not fit correctly on the E30 chassis with the S54 Engine, we did some modifications on our Airbox to get a perfect fitment on these swaps. The S54 E30 Airbox comes without the front inner canalization that usually brings fresh air from the front bumper, also the box it´s modified on the rear, near the servo unit to prevent friction in that area. All our pieces are numbered, so their origin and authenticity are granted.

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 5.5 lbs of weight when compared to the factory piece. Besides the performance benefits, the enhanced aesthetic is almost worth it on its 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. Installation is quick and easy, utilizing factory hardware. Product Details: 2.5kg lighter than the OE brace Anodized Black Mounts Retains single-piece V-brace for maximum strength and rigidity; installs with factory hardware
