- UV-stabilized resin — holds the deep finish through seasons of sun
- Factory-look proportions — complements OEM body lines
Direct bolt-on, no modification. Professional installation recommended.
Fitment. BMW G80 M3, G82 M4.
Materials & Construction
Genuine autoclaved prepreg dry carbon fiber in a deep 2x2 twill weave, cured under heat and pressure so the panel is lighter and stiffer than wet-layup carbon. Finished with a UV-stable clear coat that resists yellowing, over an OEM-grade mould for a factory-line fit.
