With a 67 or 61-inch span and a 13-inch height, the GTC-300 is an adjustable wing well-suited 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 the verification 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 include pre-pregnated carbon fiber woven sheets to achieve superior strength and light weight. All CFRP airfoils are manufactured using pre-pregnated 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 with a flat black powder coat finish.
Special Note: The mounting base covers the holes from the factory spoiler/wing.
Paint protection film add-on is available here.
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 are no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
The entire product database is based on North American vehicles (USDM), so please check whether installation on Japanese vehicles (JDM) is possible before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle. Our support team will look into it for you.)
If you order without checking compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, it does not necessarily mean they will fit Japanese models 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 checkout. 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 yourself plenty of time when ordering. If you are in a hurry, please contact us to check the delivery date 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 basically all designed and manufactured outside of Japan. Please note 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 "circuit, private property, or off-road use," 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 packing box or the product. Please understand that we will only handle returns, refunds, or replacement exchanges for products with shipping damage, defective items, or items different from what was ordered if you contact us within 7 days of receipt. Additionally, for products sold through us, we will handle warranty-related matters "only through us." Please note that we do not provide support through other companies or distributors located within Japan.
