Description
The MOSHAMMER 991.1 Ducktail Evo II is a refined interpretation of the classic ducktail design.
Developed exclusively for naturally aspirated Porsche 991.1 models, this fixed rear spoiler integrates seamlessly into the elegant silhouette of the 991. Its design is bold yet timeless as well as enhances the rear section without disturbing the original lines.
Using the MOSHAMMER engineering approach, the Ducktail Evo II combines clean aesthetics with proven aerodynamic function. The optimized airflow improves high speed stability, eliminates lift and generates measurable downforce. Every contour follows a clear purpose and creates a balanced connection between form and efficiency.
On the Autobahn as well as on track, the Ducktail Evo II shows its strength. At 200 kmh it generates around 26 kg of additional downforce, thus, increasing to approximately 41 kg at top speed. Thus, resulting in a stable and well balanced driving experience.
Perfect fit and certification
The MOSHAMMER 991 Ducktail Evo II carries TÜV testing and certification. It delivers balanced aerodynamics on both front and rear axle and ensures consistent stability at any speed.
The Ducktail Evo II is designed without a third brake light. The original brake light in the decklid grille remains fully visible and functional. This keeps the rear clean and preserves the elegant character of the 991.
Key features
Iconic ducktail design integrated into the 991 silhouette
Proven aerodynamic performance for stability and efficiency
OEM Plus installation using original factory mounting points
Clean rear design without additional brake light

Installation
The installation is carried out using the original factory screw points.
For operation as a fixed rear spoiler, the automatic spoiler lift function must be deactivated by coding.
Please note that regardless of whether the vehicle is coded or not coded, no error messages related to the electric rear spoiler will occur.
If the vehicle is not coded, the only possible warning message concerns the third brake light. For this case, we offer the LED Brake Light Simulator, which prevents this warning message. Overall, the process is completely straightforward and simple.
