This product is made-to-order, with a typical lead time of 2-3 weeks.
Every GT Series wing features an all-new, low-drag, aerodynamic 2D airfoil shape. The "2D" design allows the wing to maintain a consistent level of downforce across its entire span. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support the validation of its aerodynamic design.
Each GT Series airfoil is constructed using lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils include pre-preg carbon fiber woven sheets for superior strength and weight reduction. All CFRP airfoils are manufactured using pre-preg composite manufacturing processes (such as high-temperature autoclaving and vacuum bagging) in high-quality billet aluminum molds.
A Gurney flap is included and pre-installed on all GT-250 wings. These are ultra-lightweight and made using the pre-preg carbon fiber process.
Before Placing Your 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Verification of Compatibility
Since our entire product database is based on North American vehicles (USDM), please verify whether items are compatible with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
Please note that we cannot accept returns due to incompatibility if you place an order without confirming compatibility first.
Furthermore, please be aware that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.
○ Regarding Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically 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 via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not designed to comply with "Japanese vehicle inspection standards," and we are unable to provide strength calculation documents or similar paperwork for these inspections. 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 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 exchanges for items with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
