The 70-inch GTC-500 Carbon Fiber Adjustable Wing is the largest wing available in the APR catalog. Featuring an optimized 3D airfoil shape, the GTC-500 is ideal for high-speed touring applications, providing a sufficient amount of downforce without causing excessive drag. All GTC Series wings feature aerodynamically 3D-designed airfoils to achieve an optimal balance of downforce. This design maintains an ideal level of downforce while reducing air resistance. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support the validation of the aerodynamic design.
Each GTC Series airfoil is constructed from lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils contain pre-preg carbon fiber woven sheets that provide excellent strength and reduced weight. All CFRP airfoils are manufactured using pre-pregnated composite manufacturing processes (such as high-temperature autoclaving and vacuum bagging) in high-quality billet aluminum molds.
Supporting the wing are 10 mm "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 will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check 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 via the tabs on our homepage, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions 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. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please inquire about delivery times in advance. Please note that 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 essentially designed and manufactured outside of Japan. They are not adapted to the "Japanese vehicle inspection system," and we cannot provide strength study documents or similar for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging 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, we will only handle warranty-related matters "directly through us." Please note that we do not work through other companies or distributors located within Japan for these matters.
