BMW M4 G83 Convertible (2021–2026)

BMW M4 G83 Convertible Carbon Fiber Aero Parts (2021-2026)

The G83 generation M4 Convertible brings BMW's M division open-top coupe through the M4 and M4 Competition trims from 2021 onward. AeroBon builds real and dry carbon fiber components specifically for the G83 platform, including trunk spoilers and mirror covers. The G83 shares its trunk lid with the G23 4 Series Convertible, so the trunk spoilers listed here are cross-compatible with both models.

Currently Available

Our M4 G83 lineup includes:

  • Real Carbon Fiber Trunk Spoiler - OE Style (shared with G23 Convertible)
  • Real Carbon Fiber Trunk Spoiler - GC Style (shared with G23 Convertible)
  • Real Carbon Fiber Side Mirror Covers - Replacement Style (shared with G80 M3, G82 M4, G87 M2)
  • Dry Carbon Fiber Mirror Cap Overlays - Add-On Style (shared with G80 M3, G82 M4, G87 M2)

Choosing the Right Option

The OE Style spoiler follows a factory-adjacent profile suited to a daily-driven M4 Competition convertible, while the GC Style adds a more pronounced lip for a sportier stance. For mirrors, the Replacement Style covers swap the entire mirror cap, while the Add-On Style overlays bond directly over your factory cap without removal.

Fitment Clarification

This collection is built for the G83 M4 Convertible, which shares its trunk lid with the standard G23 4 Series Convertible (2021-2024) - so both trunk spoilers listed here are cross-compatible with the G23 430i and M440i Convertible as noted on each product page. This does not fit the G82 M4 Coupe or G26 4 Series Gran Coupe, which use different trunk lid shapes.

Quick FAQ

Q: Will these parts fit an M4 Competition Convertible?
A: Yes. Both trims share the same trunk lid and mirror housings, so all spoilers and mirror covers fit the same.

Q: Does the standard G23 430i Convertible spoiler fit the M4?
A: Yes, the trunk spoilers listed here are shared across the G23 platform since the M4 uses the same trunk lid as the standard 4 Series Convertible.

Q: Does this fit the M4 G82 Coupe?
A: No. The G83 convertible and G82 coupe use different trunk lid geometry - the trunk spoilers are not interchangeable, though mirror covers are shared.
