The 71-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 for an optimal balance of downforce. This design allows for maintaining an ideal level of downforce while reducing air resistance. 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 material. These airfoils contain pre-impregnated carbon fiber weave sheets that provide superior strength and weight reduction. All CFRP airfoils are manufactured using pre-preg composite manufacturing 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.
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Verification of Compatibility
As our entire product database is based on North American vehicles (USDM), please verify compatibility with Japanese domestic vehicles (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 assist 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 top page, this 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 if you have any questions before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual cost for large items such as body parts. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic delivery within Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Furthermore, all products are transported by air; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
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 are unable to provide strength study reports or similar documentation for Japanese inspection purposes. 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
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defects, or incorrect items if you notify us within 7 days of receipt. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle matters through other companies or distributors located within Japan.
