The Mantis kit for the BMW E9x is the most suitable angle kit for today’s drift scene, designed with cost in mind without sacrificing quality or performance. The FDF kit utilizes the factory knuckle, its strut, caliper, and bearing mount for the first time, attaching the bottom half to the FDF adapter to achieve perfect geometry, adjustability, and bump stops.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily mean 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 Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs is calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may sometimes differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
In principle, 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 order with enough time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for that purpose. 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 immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging boxes and products may sustain shipping damage. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective products, or items different from what was ordered if contacted within 7 days of receipt. 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 distributors located in Japan.
