Available with a 67-inch or 61-inch span and a 13-inch height, the GTC-300 is an adjustable wing that means serious business. The 3D airfoil shape of the GTC-300 allows for optimal airflow that provides an effective amount of downforce while reducing drag. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support aerodynamic design validation.
Each GTC 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 aluminum billet molds.
Supporting the wing are 10mm "aircraft-grade" 6061 billet aluminum pedestals finished in a flat black powder coat.
Before Ordering
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 there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether or not 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 vehicle model in the tabs on our home page, this does not necessarily mean they will fit Japanese models without modification.
All products 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 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, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually by email.
Basically, 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 allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery date. All products are transported via air freight; they are never shipped via 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 adapted to the "Japanese vehicle inspection system" (Shaken), and we are unable to provide strength inspection reports or similar documentation for this 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 of your product. Because all products are shipped internationally from outside of Japan, there may be shipping damage to the packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also 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 within Japan.
