The Corvette is an excellent drift chassis, but the position of the front upper control arm within the front wheel well can pose certain limitations compared to other platforms. FDF arms are specifically designed to address this issue by utilizing high-strength alloy steel and improved mounting points to achieve maximum clearance for both OEM and aftermarket drift knuckles. In contrast to OEM upper control arms, FDF arms provide an additional 10 degrees of clearance, significantly increasing the vehicle's angle potential. Furthermore, replacing the stock rubber bushings with chromoly rod ends further enhances the vehicle's handling characteristics.
The upper control arm length can be adjusted using the rod end adjustment range. Because the mounting angle limits the range, upper control arm shims can be added to further extend the length of the control arm.

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Confirmation of Compatibility
All product databases are based on North American specification vehicles (USDM), so please verify compatibility with Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will 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 name, and vehicle model on the tabs on our top page, 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 before ordering if you have any questions.
○ Regarding Shipping
Shipping fees are paid at the time of checkout. Shipping estimates are calculated automatically once 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.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery time. Note that all products are transported by air. They are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are fundamentally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength examination reports for this purpose. Therefore, all parts are sold for use on "circuits, private property, and off-public roads," 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 packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement items for damaged, defective, or incorrect products if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through our company." Please be aware that we do not coordinate with other companies or agencies located within Japan.
