The Subaru Impreza is a high-performance vehicle designed for rallying. Due to its excellent performance, it is increasingly being used in grip racing as well. Lowering the ride height increases grip and improves handling, but doing so causes the factory-designed kinematics to stop working as intended. The Wisefab Subaru Impreza uprights/knuckles return the roll center, bump steer, anti-squat, and camber curve to their normal range, improving roll stiffness, handling, and grip.

Before placing your order
〇 Regarding import consumption tax
At Shaft-ya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount you pay at checkout.
〇Checking compatibility
All product databases are based on North American vehicles (USDM), so please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether the listed product is compatible with your vehicle. Our support team will be happy to look into it for you.)
If you order without verifying 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 home page, this 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 delivery
Shipping costs are paid at the time of settlement. Estimates for shipping costs are automatically calculated when you enter your shipping address on the checkout page. For large products such as body parts, the automatically calculated shipping cost may sometimes differ significantly from the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. 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 not shipped by sea.
○ Regarding compliance with Japanese vehicle inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese vehicle inspection system," and we cannot provide strength calculation sheets, etc., for the purpose of the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off public roads," and installation and use are at your own risk.
○ Regarding warranties
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle warranty-related matters "only through us." We do not handle matters through other companies or distributors located within Japan.
