The BMW E90 / E92 / E92 M3 / E81 / E82 rear subframe MOD kit allows you to adjust rear grip levels by changing the position of the #7 arm. This setup requires some modifications and welding to the OEM subframe (FD legal).
Warning! This modification kit is not suitable for low-power vehicles, and extreme setups may restrict wheel travel.
Note! This mod kit only works with the latest Wisefab BMW E90 / E92 / E92 M3 / E81 / E82 rear suspension sold from December 2019 onwards.
Before placing your order
〇 About Import Consumption Tax
At 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 Checking Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify whether parts will fit Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it 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 via the tabs on our homepage, it does not necessarily guarantee a direct fit on 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 cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are transported via air freight; they are never shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength analysis reports or similar documentation for this purpose. Therefore, all parts are sold for "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 damage to the shipping box or product caused by transit. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defects, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through us, warranty support will be handled "only through our company." Please note that we do not coordinate with other companies or distributors located within Japan.
