Does the spoiler still raise and lower?

Yes. The original height adjustment and lowering are technically unchanged and the active aerodynamic function remains fully intact.

Is this a complete rear wing?

No, it is an extension that mounts onto the factory spoiler to increase what that spoiler can do.

How much downforce does it add?

Moshammer states that it provides the greatest possible downforce the original spoiler can produce; no separate figure is quoted for this article.

The mounting material is included and the extension is bonded using the special glue provided.

Will it fit a car with the factory Aerokit?

No, it is intended for cars with the standard rear spoiler rather than the original Aerokit.

Moshammer Rear Wing Spoiler Extension for 991 Porsche 911 Turbo & Turbo S

Moshammer Rear Wing Spoiler Extension takes the 991 Turbo’s own rear spoiler and asks more of it. Mounted onto the factory wing, the extension provides the greatest possible downforce the original assembly can produce, while the standard height adjustment and lowering remain completely unchanged and still active. That is the OEM+ discipline Moshammer built its name on, more aerodynamic effect without giving up a single factory function. Visually it adds depth and a race inspired edge to a familiar shape, never at the expense of the original design language. Delivered unpainted with mounting material and a TUV parts certificate (§19.3), it is made to order in small batches for owners who want the result rather than the noise.

Design and Proportion

The extension follows the shape of the factory 991 Turbo wing and adds depth to it, giving the rear a race inspired edge without rewriting the car’s design language. It is a considered addition rather than a statement piece, and once fitted it reads as though the extra height and volume were always intended. Delivered unpainted, it can be finished in body color or a contrasting satin to suit the car.

Aerodynamic Function

Mounted on the original wing, the extension provides the greatest possible downforce that the factory assembly can produce. Crucially, the original height adjustment and lowering remain technically unchanged, and the active aerodynamic rear spoiler function continues exactly as delivered. You gain aerodynamic effect without giving up a single factory behavior.

Construction and Finish

The article arrives unpainted with the mounting material included, and it is bonded in place with the special glue provided. A TUV parts certificate (§19.3) accompanies it, which matters for cars registered in Germany. Moshammer builds in small batches in Berlin, so the fit against the original wing is verified rather than assumed.

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.
