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 sake of weight reduction and rigidity, all suspension links are designed as straight, tubular, or box-type. Rod ends and spherical bearings are used instead of rubber bushings.

M models are also available.
- Original wheel speed sensors (ABS sensors) can be used. <リ> Only M models or brake discs 336mm or larger can be used.
- Wheel bearing size must be 45x85x41.
The link lengths differ between non-M and M models. Since both M and non-M shock absorbers and brakes come with both attachment types, either can be used. <リ> We have revised the kinematics, not just dropped the knuckles.
When focusing on performance, the car handles better when lowered, but the factory-designed kinematics do not function as intended. 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 is adjustable 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, while raising it decreases it.
Smaller brakes will not fit.
Kit contents:
- Pre-set suspension links.
- Uprights with hardware.
- Subframe bushings with spherical bearings.

Minimum rim size is 17 inches.
Before placing your order
○ Regarding Import Taxes
At Shaft-ya shopping site, we pay the import taxes incurred during customs clearance on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
○Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
We cannot accept returns due to incompatibility if you place an order without confirming compatibility first.
Please note that even if items are sorted by year, manufacturer, and model using the tabs on our homepage, it does not necessarily mean they will fit Japanese market vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.
○ Regarding Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated 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.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please inquire about delivery times in advance. All products are shipped via air freight. No products are shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
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 strength calculation documents or similar paperwork for these purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and usage are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging boxes and products may sustain shipping damage. We will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty-related support will only be handled "directly through us."
