This item is made-to-order; the typical lead time is 2 to 3 weeks.
With a span of either 67 or 61 inches and a height of 13 inches, 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-impregnated 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.
Special Note: The mounting base spacing is 18 inches (measured from the inside to the inside of the upper mounting brackets).
Before Placing Your Order
〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
All product databases are based on North American vehicles (USDM). Please verify whether the product can be installed on Japanese domestic vehicles (JDM) before ordering. (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 homepage, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products are 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 checkout. Shipping estimates are automatically calculated when 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 automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us to confirm the lead time in advance. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are fundamentally designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we are unable to provide strength calculation documents for such purposes. 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 inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product. Please understand that we will only handle returns, refunds, or exchanges for products with shipping damage, defects, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "exclusively through us." Please note that we do not coordinate with other companies or agencies located in Japan.
