All GT series wings feature 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 these wings to support aerodynamic design validation.
Each GT series airfoil is constructed from lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils include pre-preg carbon fiber woven sheets that provide superior strength and weight reduction. All CFRP airfoils are manufactured using a pre-impregnated composite manufacturing process (including high-temperature autoclaves and vacuum bagging) in high-quality billet aluminum molds.
Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover 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 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts 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 look into it for 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 year, manufacturer, and 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. There may be confusing expressions, so if you have any questions, please contact us before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates 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 there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow 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 not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength evaluation reports for Japanese vehicle inspections. Therefore, all parts are sold for use on "circuits, private land, and 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 may be shipping damage to the packaging boxes or the products themselves. 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. Please note that for products sold through us, warranty support will be handled "exclusively through us." Please understand that we do not provide support through other companies or distributors located within Japan.
