The Karbonius F8X M3 / M4 Carbon Interior Replacement Trim Set is a complete, OEM-replacement carbon fiber dash and door trim upgrade for the F80 M3 and F82 M4. Unlike overlay kits that bond a thin carbon veneer to your existing trim, each Karbonius piece is a full three-layer prepreg carbon fiber construction — adapted onto a complete set of genuine OEM BMW replacement trim. The result is factory-correct fitment with no added thickness, no risk of delamination, and a level of structural stability and finish quality that single-layer overlay products cannot replicate.

Each set is manufactured in Spain using 100% prepreg carbon fiber in a 2x2 gloss twill weave, autoclave-cured for consistency and long-term durability. The three-layer carbon construction ensures both a flawless surface finish and the dimensional rigidity needed to perform as a true OEM replacement rather than a cosmetic overlay. Every piece is individually numbered for authenticity and traceability.

Available as a 7-piece set for the F80 M3 sedan (including rear door trims) or a 5-piece set for the F82 M4 coupe, the kit transforms the F8X cabin with a cohesive, motorsport-grade carbon interior.
