Features:
The Verus Engineering Aggressive Rear Diffuser combines function, form, and science to provide the WRX and STI with unparalleled fitment, performance, and style.
By utilizing cutting-edge analysis software in our R&D process, we were able to increase performance for a given build volume, increase downforce, and reduce drag by adding a rear diffuser to more of the VA chassis. Using in-house scan data allowed us to design a product with both precise fitment and a high-quality finish.
The aggressive rear diffuser is designed for owners who value both functionality and form, with an especially aggressive strake design that makes the diffuser stand out.

Before Ordering
〇 About Import Taxes
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Fitment Confirmation
Our entire product database is based on North American (USDM) vehicles, so please confirm whether the product can be installed on Japanese (JDM) vehicles before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model on our top page, it does not necessarily guarantee fitment on Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs is automatically calculated when you enter your shipping address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost for large items such as body parts. In such cases, we will contact you individually by email.
All products are fundamentally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us to check the delivery date in advance. All products are transported via air freight. No products are shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese Vehicle Inspection (Shaken) System," and we cannot provide documents such as structural strength analysis for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility that packaging boxes or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
