Wisefab solid (rigid) aluminum bushing kit designed specifically for the BMW E46 rear subframe, dramatically increasing rigidity. A high-performance part recommended for users who drive on circuits.
The stock rear member uses large rubber bushings to enhance ride comfort and quietness. However, these bushings undergo significant deflection during driving due to aging, leading to alignment changes and unnecessary movement of the subframe itself, which degrades the rear tire's ground feel and creates discomfort for the driver. This rigid bushing kit is manufactured from aluminum and does not deflect like stock rubber bushings, allowing the driver to feel road conditions and grip levels as if firsthand.

Before Ordering
〇 Regarding Import Duties
At Shaftoya 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 paid at checkout.
〇 Compatibility Verification
Our entire product database is based on North American specification vehicles (USDM). Please confirm whether the product is compatible with Japanese specification vehicles (JDM) before ordering. (If you are unsure if the 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 order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by year, make, and model using the tabs on our home page, this does not guarantee 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 costs are paid at the time of settlement. For shipping estimates, the cost will be calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a rush, please inquire about delivery times in advance. Note that all products are transported by air. They will not be shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
In principle, all products we handle are 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 evaluation reports for that purpose. 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. 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 provide returns, refunds, or replacement products only if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, warranty support will be handled "only through us." Support via other companies or distributors located in Japan is not available.
