With a span of 67 inches or 61 inches and a height of 13 inches, the GTC-300 is an adjustable wing that means serious business. The GTC-300's 3D airfoil shape allows for optimal airflow that delivers an effective amount of downforce while reducing drag. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support the validation of its aerodynamic design.
Each airfoil in the GTC series is constructed from lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils contain 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.
Supporting the wing are 10mm "aircraft-grade" 6061 billet aluminum pedestals with a flat black powder-coated finish.
Before Placing an Order
〇 Regarding Import Consumption Tax
At the 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 all product databases are based on North American vehicles (USDM), please confirm whether they can be installed on 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 look into it 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 in the tabs on our top page, this 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 payment. Shipping estimates are calculated automatically when 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 via 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 for your order. If you are in a hurry, please contact us in advance to check the delivery date. Please note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that the products we handle are basically designed and manufactured outside of Japan. They are not adapted to the "Japanese vehicle inspection system" at all, and we cannot provide strength calculation reports or similar documents for the Japanese vehicle inspection system. Therefore, all parts are sold for use on "circuits, private land, and off-road," and we ask that you install and use them at your own risk.
○ Regarding Warranty
Please check the contents immediately when the product arrives. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing box or the product. Please understand that we will only handle returns, refunds, or replacement exchanges for products with shipping damage, defective products, or products different from your order if you contact us within 7 days of receipt. Please note that for products sold through our company, warranty support will be handled "exclusively through our company." We do not provide support through other companies or distributors located in Japan.
