The Subaru Impreza is a high-performance car 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 prevents the factory-designed kinematics from working as intended. Wisefab Subaru Impreza knuckles/uprights bring the roll center, bump steer, and camber curve back to the normal range, improving roll stiffness, handling, and grip.

Before Ordering
〇 About 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 beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all of our product databases are based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate 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 in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of payment. An estimate for shipping costs will be 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 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 about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to check the delivery date. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The 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 cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," 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, packaging boxes or the products themselves may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what was ordered. Furthermore, regarding products sold through us, we will handle warranty matters "only through us." Please note that we do not provide support through other companies or distributors located within Japan.
