Product description

A full dry carbon replacement trunk lid for the G80 M3 / G82 M4, with a CSL-inspired ducktail that cleans up rear airflow and drops real weight over the steel OEM panel.

Why owners choose it

  • Genuine dry carbon — hand-laid prepreg, autoclave-cured for OEM-grade fitment and a deep 3K twill finish
  • Real weight savings — lighter than the steel factory trunk, lowering rear mass
  • CSL ducktail profile — sharpens the rear deck and cleans airflow off the back
  • UV-stable clear coat — resists yellowing under sun and frequent detailing
  • Direct bolt-on — uses all factory mount points; pre-fitted for OEM emblems, lock cylinder, and weatherstripping

Direct bolt-on replacement panel. 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.
