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 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-impregnated carbon fiber woven sheets for superior strength and weight reduction. All CFRP airfoils are manufactured using pre-impregnated composite production processes (such as high-temperature autoclaves and vacuum bagging) in high-quality aluminum billet molds.
Supporting the wing are 10mm "aircraft-grade" 6061 billet aluminum pedestals with a flat black powder coat finish.
Before Placing an Order
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 you will not be charged any additional fees 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 the product can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure whether the 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 name, and vehicle model using 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 if you have any questions before placing your order.
○ 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, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international delivery takes approximately 7 to 14 days, so please allow plenty of time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Furthermore, all products are transported by air. They are not shipped by 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 compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for these regulations. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-public roads," and we ask that you take full responsibility for their installation and use.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related issues will be handled "exclusively through us." Please note that we do not work with other companies or agencies located within Japan for these matters.
