2012-2016 Porsche Cayman Carbon Fiber Rear Diffuser (by Verus Engineering)
When properly designed, a rear diffuser can be a highly efficient downforce-generating device. We aimed to create a functional rear diffuser worthy of the Porsche 981 GT4 by utilizing state-of-the-art research and development processes. By using carbon fiber, sheet metal, and rigid rubber, we have created a structure that fuses form and function.
By utilizing scan data, CAD, and ANSYS Fluent analysis software, we were able to design and produce a functional and beautiful rear diffuser worthy of this Porsche chassis. The three main diffuser sections are made of 2x2 twill, autoclave-cured carbon fiber. The strakes are made of highly durable polyurethane for long life.
The entire unit is bolted to various parts of the chassis via multiple metal plate brackets. No drilling or modification is required to install this rear diffuser.
Features
- 2x2 twill, autoclave-cured, 1.5mm thick carbon fiber construction
- Lightweight bonded carbon reinforcement on top of the main diffuser planes for a rigid assembly
- Durable and replaceable strake design
- CNC laser-cut and bent 5052 aluminum brackets
- Stainless steel hardware used throughout
Benefits
- Improved vehicle performance through increased downforce and reduced drag

- Durable, replaceable strake design for longevity
- Modular design - add flat underbody covers for increased performance

Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
As our product database is primarily based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese market vehicle (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, it does not necessarily guarantee that they will fit a Japanese model vehicle without modification.
All product descriptions have been translated into Japanese using translation software. Please be aware that there may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan and are not compliant with the "Japanese Vehicle Inspection (Shaken) system," nor can we provide strength calculation documents for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. We will only provide returns, refunds, or replacement products if we are notified within 7 days of receipt regarding products with shipping damage, defective products, or incorrect items. Please understand that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not handle support through other third-party companies or agencies located within Japan.
