This rear diffuser is a newly released dry carbon fiber product from AutoTecknic for the G8X M3/M4. This diffuser is designed to attach directly to the factory lower mounting points, allowing for quick and easy installation. Manufactured using 100% genuine 3K twill weave (2x2) pre-preg carbon fiber and our proprietary autoclave technology, this diffuser is finished with multiple layers of high-gloss, UV-resistant clear coat. Following the motorsport ideal of weight reduction, we employ an autoclave vacuum forming process to produce a lip with superior strength and fitment.
The name "dry carbon fiber" comes from its manufacturing process. Dry carbon fiber is formed using "pre-preg" or impregnated carbon material pieces. These carbon pieces are first placed in a mold and then properly cured in a sealed vacuum environment (autoclave). This method minimizes impurities and results in carbon that is lighter than the "wet" method. By using autoclave vacuum extraction when producing dry carbon, there are fewer pinholes in the carbon, and air bubbles are virtually non-existent. Dry carbon is the highest quality carbon fiber product produced.
This AutoTecknic dry carbon performance rear diffuser comes with durable and precision mounting clips, and utilizes our autoclave technology to achieve ultimate light weight, high durability, and an accurate fit.

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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please check if the product can be installed on Japanese vehicles (JDM) before placing your order. (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 assist 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 model year, manufacturer, and vehicle model via the tabs on our home page, it does not necessarily guarantee that they will fit 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 Delivery
Shipping costs are paid at the time of settlement. Shipping estimates are automatically calculated 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.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, 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 confirm delivery times. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar items for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-public roads," and installation and use are at your own risk.

Please check the contents of your order as soon as it arrives. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "only through us." Please note that we do not coordinate with other companies or agencies located within Japan.
