BMW 4 Series G26 Gran Coupe Carbon Fiber Parts (2021-2026)

The G26 is BMW's 4-door 4 Series Gran Coupe, spanning 430i and M440i trims, and shares many components with the electric i4 (eDrive35, eDrive40, M50). AeroBon's real and dry carbon fiber trunk spoilers, mirror covers, and antenna cover are molded to match the G26's factory profiles for a clean, track-inspired upgrade.

Currently Available

Our G26 lineup includes three trunk spoiler profiles, all shared with the i4:

  • Real Carbon Fiber Trunk Spoiler - GC Style
  • Real Carbon Fiber Trunk Spoiler - H Style
  • Real Carbon Fiber Trunk Spoiler - MP Style (Motorsport Performance)

Also available:

  • Real Carbon Fiber Side Mirror Covers - Replacement Style (shared with G42, G20, G22, G23, i4)
  • Real Carbon Fiber Mirror Cover - Replacement Style (shared with G22, G23, i4)
  • Dry Carbon Fiber Mirror Cap Overlays - Overlay Style (shared with G42, G20, G22, G23, i4)

  • Dry Carbon Fiber Shark Fin Antenna Cover (shared with i4 and G60/i5 5 Series)

Choosing the Right Option

GC Style offers a subtle, factory-look profile, H Style adds a taller kick, and MP Style gives a sportier lip. For mirrors, Replacement Style swaps the entire factory cap, while Add-On/Overlay styles mount over your existing cap without removal.
