Fitment. BMW G20 3-Series & G80 M3 (2019+). Also fits G22 / G82.
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.
