Will a fixed ducktail hurt cooling on a 991.2 Carrera?

No, according to Moshammer. The Ducktail Evo II carries integrated air channels that guide airflow toward the intercoolers, and Moshammer states that cooling performance is maintained even under high load. That addresses the main concern with fixed spoilers on the 3.0 twin-turbo 991.2 cars, where the factory spoiler normally rises at speed and owners fear a fixed part will starve the intercoolers.

Does the rear spoiler need coding after fitting the Moshammer Ducktail Evo II for 991.2?

Yes. For operation as a fixed spoiler, the automatic spoiler lift function has to be deactivated by coding, which a Porsche dealer or a specialist workshop can do. If the car is left uncoded, Moshammer says the only possible warning message concerns the third brake light, and the Moshammer LED Brake Light Module is available to prevent it.

Which 991.2 models does the ducktail fit?

Moshammer lists every 991.2 Carrera, GTS and GT3 Touring, in Coupe, Targa and Cabriolet form where the model was offered. That covers the Carrera, Carrera S, Carrera 4, Carrera 4S, Carrera T, the GTS models and the Targa 4 range. It is not compatible with the 991.2 GT3 equipped with the fixed rear wing.

Is the Moshammer Ducktail Evo II road legal?

The Moshammer Ducktail Evo II for 991.2 cars is supplied with a TUV certificate according to §19.3 and was TUV tested at speeds above 300km/h. That paperwork covers road use in Germany. Rules for bodywork changes vary outside Germany, so owners in other markets should check local inspection requirements before fitting.

Does the ducktail arrive painted?

No. The ducktail is delivered primed and unpainted, together with the mounting hardware and the TUV certificate. That lets a body shop match the factory color code exactly or apply a contrast finish, so paint should be budgeted for before installation. Paint is not included in the price.

Can the car be returned to standard later?

Yes. The Ducktail Evo II installs at the original factory screw points without drilling or cutting, so removing it restores the standard rear deck. If the spoiler lift function was deactivated for fixed operation, it should be re-enabled by coding at the same time so the factory spoiler works as delivered.

Moshammer Ducktail Evo II for 991.2 Porsche 911 Carrera & GT3 Touring

Moshammer’s Ducktail Evo II for 991.2 Porsche 911 Carrera, GTS and GT3 Touring models puts the shape first seen on the 1973 Carrera RS 2.7 back on the rear deck without asking the turbocharged cars to give up cooling. That has always been the catch on the 3.0 twin-turbo 991.2, where owners worry that a spoiler which never rises will cut airflow to the intercoolers under the engine lid. Moshammer builds air channels into the spoiler to guide air toward the intercoolers, and had the design TUV tested at speeds above 300km/h. Built in Berlin to OEM+ standards, it suits the owner who wants the best-known silhouette in 911 history and would rather nobody could tell where the factory stopped.

Ram Air Technology

Air channels run through the body of the spoiler and guide airflow toward the intercoolers, so the Evo II does thermal work as well as styling. That matters most on the 3.0 twin-turbo Carrera, Carrera S, Carrera 4, Carrera T and GTS models, where a fixed spoiler has been the usual objection on owner forums. The GT3 Touring is different: its 4.0 flat-six is naturally aspirated and has no intercoolers to feed, so on that car the Evo II is a choice about shape and fixed aero rather than cooling.

High Speed Composure

A fixed profile behaves the same way at every speed, with no motor, hinge or deployment point in the equation. Moshammer had the design TUV tested at speeds above 300km/h (186mph), which is the figure that matters to an owner who uses derestricted roads or track days. On a car that never leaves town and motorway speeds, the look is the reason to buy it.

Installation and Reversibility

The Ducktail Evo II for 991.2 cars mounts at the original factory screw points, so nothing on the rear deck is drilled or cut. For operation as a fixed spoiler, the automatic spoiler lift function has to be deactivated by coding, a short job for a Porsche workshop with the right diagnostic equipment. The part arrives primed and unpainted, and most owners have it finished in the factory color code before fitting. If the car ever needs to return to standard, the ducktail comes off at the same points.

About Moshammer

Moshammer Automotive is a Berlin-based manufacturer of OEM+ aerodynamic refinement for Porsche, with a smaller line for Mini, Audi, BMW, and Mercedes-Benz. The house style is restraint with intent: parts drawn to look as though the factory had gone one step further, developed against original mounting points, TUV-documented where German road use demands it, and produced in small batches rather than stocked in volume. Their catalog spans single accents such as vent grills and wing end blades through complete Downforce and Tradition RS aero programs, alongside a range of multipiece forged wheels made to order in any size, width, and finish.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
