With a span of 67 or 61 inches and a height of 13 inches, the GTC-300 is an adjustable wing suitable for serious business. The 3D airfoil shape of the GTC-300 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 aerodynamic design validation.
Each airfoil in the GTC series is constructed from lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils feature pre-preg carbon fiber woven sheets for superior strength and weight reduction. All CFRP airfoils are manufactured using pre-preg composite production 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 coat finish.
Special Note: The mounting base is located at the edge of the trunk lid.
Before Ordering
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
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with 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 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 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 ordering.
○ Regarding Delivery
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 calculated automatically. 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 when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all 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 items for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
