The MOSHAMMER 991.1 Ducktail Evo II is a true masterpiece of aerodynamic refinement.

Designed exclusively for the non turbo natural aspirated Porsche 991.1 and for the Porsche 991.2 GT3 Touring models, it represents the next evolution of the classic ducktail idea. This fixed rear spoiler blends seamlessly into the elegant silhouette of the 991 and brings a bold yet timeless character to the rear section.

Developed using the advanced MOSHAMMER engineering approach, the Ducktail Evo II unites pure aesthetics with proven function. The airflow is optimized to deliver clean stability at high speeds with no lift but measurable downforce. Every curve and contour follows a purpose, creating the perfect connection between elegance and aerodynamic efficiency.

On racetracks and high speed Autobahns, the Ducktail Evo II shows its capabilities. At 200 kmh it generates an additional 26 kg of downforce and increases to around 41 kg at top speed, resulting in a perfectly balanced driving experience.

Perfect Fit

The MOSHAMMER 991 Ducktail Evo II is TÜV tested and certified. It delivers balanced aerodynamics for both the front and rear axles and ensures constant stability at any speed.

The Ducktail Evo II does not include a third brake light. The original brake light in the decklid grille remains fully visible and functional. The proportions stay clean and the elegant character of the 991 rear design is preserved.
