At 67 inches wide and 10 inches tall, 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 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 materials. These airfoils contain pre-preg carbon fiber woven sheets for 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 aluminum billet molds.
Supporting the wing are 10mm "aircraft-grade" 6061 billet aluminum pedestals in 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 you will not be charged any additional fees 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 or not parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product fits 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 using 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 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 are rare cases where there is a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within 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 the delivery date. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar for Japanese vehicle 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 of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be provided "only through us." We do not provide support through other companies or distributors located in Japan.
