With a span of 67 or 61 inches and a height of 13 inches, the GTC-300 is an adjustable wing suited for 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 aerodynamic design validation.
Each airfoil in the GTC series is constructed of lightweight and durable Carbon Fiber Reinforced Polymer (CFRP) composite materials. These airfoils include pre-impregnated carbon fiber woven sheets to achieve superior strength and light weight. All CFRP airfoils are manufactured using pre-impregnated composite production processes (such as high-temperature autoclaves 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 coat finish.
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 are 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 the product can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check 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 name, and vehicle model on 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. 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. Estimates for shipping costs 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 by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic delivery in Japan, international delivery takes about 7 to 14 days, so please place your order with plenty of time. If you are in a hurry, please contact us to check the delivery date in advance. Note that all products are transported by air. They are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength study reports or similar documents for Japanese vehicle inspections. 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.
○ Regarding Warranty
When the product arrives, please check the contents immediately. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging boxes or the products. Please understand that we will only handle returns, refunds, or replacement exchanges for products with shipping damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please also note that for products sold through our company, we will handle warranty-related matters "only through our company." Please be aware that we do not handle matters through other companies or distributors located within Japan.
