2016-2018 Ford Focus RS Rear Diffuser (by Verus Engineering)
Our simple bolt-on diffuser reduces lift and drag on the Mk3 Focus RS. Hatchback vehicles are known to suffer from drag due to the dead-water area behind the vehicle. Our functional and aesthetic diffuser tackles this issue head-on. Our diffuser is designed to increase downforce and reduce drag by shrinking the dead-water area.
By utilizing state-of-the-art analysis software during our R&D process, we were able to extract higher performance from the given build volume. The addition of the rear diffuser increased downforce and reduced drag.
During the design process, we utilized our in-house scan data. This resulted in a product that offers a fit and finish close to OEM. This rear diffuser was designed for owners who value both functionality and form. It features a subtle strake design that harmonizes with the vehicle's factory body lines.

Before You Order
○ Regarding Import Consumption Tax
At Shaft-ya 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.
○ Confirming Fitment
Our entire product database is based on North American (USDM) vehicles; please confirm whether or not these products can be installed on Japanese (JDM) vehicles before ordering. (If you are unsure if a listed product fits 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 fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model in the tabs on our top page, it does not necessarily guarantee fitment on Japanese-market vehicles without modifications.
All product descriptions have been translated into Japanese using translation software. 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 automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. 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 plenty of time for your order. If you are in a rush, please contact us in advance to confirm delivery times. All items are shipped via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural calculation documents or similar paperwork for the purpose of the Japanese inspection system. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not coordinate with other companies or agencies located in Japan regarding warranty issues.
