Collection: BMW 4 Series F33 Convertible (2013–2020)

BMW 4 Series F33 Convertible Carbon Fiber Parts (2013-2020)

The F33 is BMW's first-generation 4 Series convertible, spanning 428i and 435i trims and closely related to the F83 M4 Convertible. AeroBon's real and dry carbon fiber trunk spoilers and mirror cap overlay are molded to match the F33's factory profiles for a clean, track-inspired upgrade.

Currently Available

Our F33 lineup includes:

• Real Carbon Fiber Trunk Spoiler - MV Style (Motorsport Version, shared with F83 M4 Convertible)
• Real Carbon Fiber Trunk Spoiler - H Style (High Kick, shared with F83 M4 Convertible)
• Dry Carbon Fiber Mirror Cap Overlays - Add-On Style (shared with F32 Coupe and F36 Gran Coupe)

Choosing the Right Option

MV Style gives a subtle, factory-look profile, while H Style adds a taller kick for a more aggressive stance. The mirror cap overlay mounts over your existing factory cap without removal, and is shared across the 4 Series coupe, convertible, and Gran Coupe body styles.

Fitment Clarification

Both trunk spoiler styles are shared with the F83 M4 Convertible, since the F33 and F83 use the same trunk lid profile. The mirror cap overlay is shared across the F32 Coupe, F33 Convertible, and F36 Gran Coupe, since these all use matching mirror housings.
