Product Details

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 and the Porsche 991.2 GT3 Touring, 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.

Installation

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.

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

  • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
  • Warranty claims must be processed in person at an authorized Porsche Service Center
  • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
  • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
  • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

  • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
  • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
  • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
  • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

  • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
  • A completed warranty certificate
  • Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.

Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.
