Product Description
Diffusers work in conjunction with other aerodynamic components of a car to help produce downforce. As the car pushes air out of the way while moving forward, the air molecules at the rear of the car are disturbed, creating a low-pressure vacuum. To guide the high-speed airflow coming from under the car, the diffuser redirects the high-speed airflow to smoothly transition into the low-pressure vacuum at the rear. This creates a smoother flow of air under the car and improves the performance of other aerodynamic components such as aerodynamic wings.
- Pre-preg carbon fiber manufacturing process
- Version 1 Diffuser with Undertray

Before You Order
〇 Regarding Import Consumption Tax
At the Shafutoya 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 Fitment
All product databases are based on North American vehicles (USDM). Please confirm whether they can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if the listed product will fit your vehicle, please feel free to contact us. Our support team will investigate 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 year, manufacturer, and model using the tabs on our home page, it does not necessarily mean they will fit Japanese models without modification.
All products 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 payment. Estimates for shipping costs are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery dates. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation reports for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products that differ from your order. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or agencies located within Japan.
