Available in 67-inch or 61-inch spans with 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 air resistance. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support the verification of its aerodynamic design.
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 that provide excellent strength and reduced weight. All CFRP airfoils are manufactured using pre-impregnated composite manufacturing processes (such as high-temperature autoclaving and vacuum bagging) in high-quality aluminum billet molds.
Supporting the wing are 10 mm "aircraft-grade" 6061 billet aluminum pedestals finished in a flat black powder coat.
Special Note: The mounting base covers the holes from the factory spoiler/wing. Span>
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
All product databases are based on North American vehicles (USDM). Please confirm whether or not parts can be installed on Japanese 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 investigate 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 home 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.
〇 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.
All products are generally 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 check the delivery date. Please note that all products are transported by air. They are never shipped by sea freight.
〇 Regarding Compliance with Japanese Vehicle Inspection
All products handled by our company are fundamentally designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. 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.
〇 Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that for products with shipping damage, defective products, or products different from your order, we will only handle returns, refunds, or exchanges if you contact us within 7 days of receipt. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located in Japan.
