Complete the aggressive profile of your AMG GT 4-Door Coupe (X290) with the factory-original Static Carbon Fiber Rear Wing. As the centerpiece of the AMG Aerodynamics Package (Code B26), this fixed wing is engineered to provide significant downforce at the rear axle, increasing high-speed stability and cornering grip beyond the capabilities of the standard retractable spoiler.

Aerodynamic Performance
-
Increased Downforce: Specifically tuned to work with the front splitter and rear diffuser to balance the vehicle’s “lift” characteristics.
-
Track Stability: Reduces rear-end “lightness” during hard braking and high-speed directional changes.
-
Lightweight Construction: The hollow-core carbon fiber construction ensures that while the wing adds downforce, it adds negligible weight to the trunk lid.
Conversion Guide: Active to Static Wing
If you are upgrading from the standard Retractable (Active) Spoiler to this Static Carbon Wing, please note the following requirements:
-
Fixed Wing Base: You must replace the motorized “active” base with the Fixed Wing Base (A2907901979).
-
Spoiler Deactivation: Once the motor is disconnected, the car will trigger a dashboard warning and limit top speed to 200 km/h (124 mph).
-
Coding/Module: You will need an AMG Spoiler Deactivation Module or SCN coding via XENTRY to tell the vehicle’s ECU that it now has a permanent aerodynamic setup.
Why Choose Genuine Mercedes-AMG?
While many aftermarket “Black Series” replicas exist, they often use a fiberglass core wrapped in a thin layer of carbon. Genuine Mercedes-AMG Carbon Wings are full-carbon structures. They are wind-tunnel tested to ensure they don’t oscillate (vibrate) at 300 km/h and feature internal reinforcements at the mounting points to prevent the wing from ripping off the trunk under high aero loads.
