Moshammer Rear Diffuser for Porsche 718 Cayman & Boxster

Moshammer Rear Diffuser gives the 718 Cayman and Boxster the lower rear detail their proportions have always deserved. Moshammer’s Berlin studio treats aerodynamics and appearance as one problem, so this profile works the air leaving the car while reading as an OEM+ design element rather than an add-on. Because it replaces a flat panel with genuine structure, its effect on how the car sits is out of all proportion to the size of the part. It arrives unpainted with mounting material and a TUV parts certificate (§19.3), ready for your painter to match the body or deliberately contrast with it. One condition narrows the audience usefully: it suits cars built without rear parking sensors.

Design and Stance

The 718 is a car of tight surfaces and short overhangs, and the standard rear leaves a wide flat area below the bumper that undersells it. Adding depth and structure there lowers how the car reads without touching ride height or bodywork. Moshammer keeps the shape close enough to Porsche’s own language that most observers assume it is a factory option.

Aerodynamic Purpose

Moshammer describes the part as providing optimal aerodynamic properties, which in practice means the air leaving the underbody is given an organised exit instead of spilling out. That is why the piece is developed as a functional component and then styled, rather than the reverse. Coverage runs across Cayman and Boxster, including T, S and GTS models.

Unpainted by Design

Every example ships unpainted, on the assumption that the owner will decide the finish. On a light car a satin black diffuser adds visual weight low down, while a colour code match keeps the rear looking entirely standard until you study it. Mounting material is supplied with the part.

Notes

Moshammer parts ship directly from Germany. Import taxes, duties, and tariffs may apply upon delivery and are the responsibility of the buyer. These fees are neither collected nor paid by Bulletproof Automotive.
Only for 718 models built without PDC parking sensors. Sensor-equipped cars are not covered by this diffuser.
The GT4 and GTS 4.0 are outside the application, contact us if you are unsure which rear your car carries
Delivered unpainted, so allow for paint or a satin finish before installation
Produced to order in Berlin, which means a production wait rather than off-the-shelf shipping

Frequently Asked Questions

Why does it exclude cars with parking sensors? The diffuser occupies the area where PDC sensors are mounted on the lower rear, so Moshammer restricts the application to cars specified without them.
Does it cover both Cayman and Boxster? Yes, including T, S and GTS versions. The GT4 and GTS 4.0 use a different rear and are not covered.
How is it finished? It is supplied unpainted. Owners typically choose satin black, gloss black, or the car’s own colour code depending on how visible they want the part to be.
Does it come with the parts needed to fit it? Yes. The mounting material is included, along with a TUV parts certificate (§19.3) documenting the component.

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.
