Moshammer Decklid Spoiler for 991 Porsche 911 Carrera

Moshammer Decklid Spoiler is for the 991 owner who wants the rear deck to sit differently without announcing it. Moshammer calls it the softer version of its ducktail, and it carries an aggressively raised extension area that lifts and sharpens the deck line while leaving the car’s original hardware completely unchanged. The Porsche active aerodynamic rear spoiler still deploys and retracts normally, so there is no mechanism to remove, no coding to arrange and nothing that complicates a dealer visit. It bonds on with the special glue provided, arrives unpainted with the mounting material and comes with a TUV parts certificate (§19.3), which puts it well ahead of the unapproved lips this platform tends to attract. Made to order in Berlin, it suits an owner who prefers a car that rewards a second look rather than demanding the first one.

Design Language

This is the gentlest way to change the rear of a 991. The raised extension area gives the deck lid a firm step and a stronger horizontal emphasis, enough to alter the car’s stance in the mirror without ever suggesting an aftermarket part. Because it spans the 991.1 and 991.2 in coupe, Targa and Cabriolet form, it is also the most broadly applicable rear piece Moshammer builds for the platform.

Aerodynamic Function

The spoiler delivers optimal aerodynamic properties while the Porsche active aerodynamic rear spoiler continues to work untouched. Nothing about the factory system is compromised, so the car retains its variable aero behaviour and gains a fixed profile above it. For an owner who values originality, that lack of intervention is the point.

Bonded Installation

Fitting is a bonded installation using the special glue provided with the part, so there is nothing drilled and no original hardware altered. Surface preparation and alignment determine how seamless the final result looks, which makes this a job for an experienced installer working with a painted, fully cured part. The mounting material is included in the delivery.

Frequently Asked Questions

How does this differ from the ducktail? Moshammer describes it as the softer version of the ducktail. It has an aggressively raised extension area that sharpens the deck line rather than reshaping the whole rear profile, so the change is more subtle.
Does it affect the active rear spoiler? No. The Porsche active aerodynamic rear spoiler function is maintained and unaffected, and no original hardware is changed.
How is it fitted? It is bonded to the deck lid with the special glue supplied. Paint the part and let it cure first, then have an experienced installer handle preparation and alignment.
Which 991 variants does it suit? Moshammer lists it for all 991 Carrera, S, 4, 4S, GTS, Targa and Cabriolet models, covering both C2 and C4 across 991.1 and 991.2 cars.
Is documentation included? Yes. A TUV parts certificate (§19.3) is supplied with the spoiler, which is what most European inspection authorities look for.

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.
