The Wisefab BMW E9x rear suspension kit can be installed on various BMW models: E90, E91, E92, E81, E82, E87, and E88. All metal components of the E90 rear suspension, including sheet metal parts, tubes, tube ends, and rod end housings, are made of high-tensile steel. Additionally, for the purposes of weight reduction and rigidity, all suspension links are designed to be straight, tubular, or box-type. Rod ends and spherical bearings are used, and no rubber bushings are utilized.

M models are also available.
- Original wheel speed sensors (ABS sensors) can be used. <リ> Only M models or brake discs of 336mm or larger can be used.
- Wheel bearing size must be 45x85x41
The link lengths differ between non-M and M models. The shock absorbers and brakes can be used with either, as M and non-M components are equipped with both attachments. <リ> We have not only dropped the knuckles but also revised the kinematics.
When focusing on performance, the car will handle better when lowered, but the factory-designed kinematics will not function properly as is. This kit provides superior kinematics for a lowered ride height. It raises the roll center and corrects camber gain, anti-squat, and bump steer to achieve maximum grip. <リ> Easy camber adjustment.
Since the top link is a straight tubular type, camber can be adjusted simply by changing its length. <リ> Bump steer adjustment.
Bump steer can be adjusted by changing the position of the rod end within the slot. <リ> Adjustable anti-squat.
Anti-squat can be adjusted by changing the height of the top-forward link on the upright. This can be done trackside in under 10 minutes. Lowering the link increases anti-squat, and raising the link decreases it.
Smaller brakes will not fit.
Kit contents:
- Pre-set suspension links.
- Uprights with hardware.
- Subframe bushings with spherical bearings.

Other components
- The hub-to-hub length (track) is the same as the original, as it is defined by the length of the half-shafts.
- This kit assumes the use of lower (shorter) springs or coilovers to lower the ride height.
- Possibility of using larger CV joints Ø110mm (Driveshaftshop 1200 hp).
Minimum rim size is 17 inches.
Before placing your order
〇 Regarding import consumption tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Confirmation of compatibility
Our entire product database is based on North American (USDM) vehicles, so please verify whether parts can be installed on Japanese (JDM) vehicles before placing your order. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Furthermore, please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in 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 costs are paid at the time of settlement. Estimates for shipping can be automatically calculated by entering 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding compliance with Japanese vehicle inspections (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength calculation sheets or similar documentation for Japanese inspections. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-public roads," and you assume full responsibility for their installation and use.
○ Regarding warranties
Please check the contents immediately upon arrival of your product. As 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 exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defects, or items that differ from your order. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
