Just when we thought we’d seen it all for the E9X M3 chassis, a new contender arrived from Germany this year: the Carbon Production E9X M3 GT4 Front Aero Kit. Handmade in Germany using motorsport-grade prepreg carbon fiber and autoclave curing, this front lip system immediately impressed our entire team. The craftsmanship, fitment, and design go beyond the typical aftermarket solution, it’s built for real aerodynamic performance with proven on-track and street testing behind it.

Full kit includes carbon fiber front lip, carbon fiber undertray, mounting hardware, and drilling template.
