Available in 67-inch or 61-inch spans with 13-inch height, the GTC-300 is an adjustable wing suitable for serious business. The 3D airfoil shape of the GTC-300 allows for optimal airflow that provides 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 of lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils include pre-preg carbon fiber woven sheets that provide superior strength and reduced weight. 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 10 mm "aircraft grade" 6061 billet aluminum pedestals with a flat black powder coat finish.
Special Note: The mounting base covers the holes of the factory spoiler/wing.
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 other than the total amount paid at checkout.
〇Confirmation of Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will check for you.)
If you 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 top page, this 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 if you have any questions before ordering.
○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, there may occasionally be a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. 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 order with time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They will not be shipped by sea.
○Regarding Compliance with Japanese Vehicle Inspections (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not adapted to the "Japanese vehicle inspection system," and we cannot provide strength calculation documents for Japanese vehicle inspections. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and please install and use them 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 itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or products different from what was ordered if contacted within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." Please understand that we do not coordinate with other companies or agencies located within Japan.
