The Toyota Supra A90 is one of the most talked-about new cars. Its combination of rear-wheel drive and a turbocharged inline-six engine offers great potential for drifting. At Wisefab, we have developed a PRO-level lock kit for this chassis. This product has been tested by skilled drivers in Japan and the USA, and we are pleased to be able to offer it to our customers.
All metal components of the Wisefab A90 front suspension are made of high-tensile steel, including sheet metal components, tubes, tube ends, and rod end housings. We use rod ends and spherical bearings, with no rubber bushings.

Recommended alignment parameters are as follows:
Toe in/out: If Ackermann is 0 or negative, toe is 2mm out. If Ackermann is positive, toe is 0
Camber: -7 +/-0,3
Caster: 6 +/-0,3 >
-
65-degree lock, parallel steering.
You can adjust the steering geometry to Ackermann, positive or negative, in just a few minutes, even trackside, without disturbing the alignment.

-
One-piece lower control arm design.
Replaces the lower links with a single arm. When drifting at high steering angles, rigidity and packaging become issues. Therefore, a one-piece lower arm is used. -
Higher Roll Center (RC).
The Wisefab knuckle has a lowered joint, which raises the front RC when the ride height is lowered, increasing roll stiffness and allowing you to remove the front anti-roll bar (sway bar), which is very difficult to package at high lock angles. -
Very good camber control and minimal bump steer even at high steering angles.
In a drift car, dynamic camber control and bump steer are far more important than static camber control. Our kinematics ensure that camber provides excellent front grip and bump steer is minimized across the entire steering range. -
Steering jack control.
While drifting, as the steering angle increases, jacking also increases—even with the same geometry—which can be a problem. We have modified the geometry to ensure that no handling issues occur. -
Consistent and predictable self-aligning torque.
Caster is not the only key parameter for providing sufficient self-aligning torque, especially at high lock. It is a combination of various parameters to maintain consistent trail and self-aligning torque. With our setup, the steering wheel always rotates in the direction of travel and will not get stuck at full lock. - Genuine wheel speed sensors (ABS sensors) can be used.

Important details for component installation
- Wheel bearings: Front wheel bearings must be sourced from a BMW E90. Part number 31216765157. OEM cannot be used.
- Wheels: Wheel bearings are 5x120 PCD. This means OEM wheels cannot be used.
- Brakes: We recommend using BMW E90 or E90 M3 brakes. OEM brake calipers can be used with the included E90 M3 brake caliper adapters. Some processing may be required for the brake adapters. Genuine brake discs cannot be used. If using OEM brake calipers, you must obtain appropriate brake discs. Ensure the brake disc is centered in the caliper.
- Struts: The strut lower mounting diameter must be 56 mm or 62 mm. The genuine mounting diameter is 56 mm. You must use height-adjustable coilovers.
- Steering rack: Using the stock steering rack is not recommended, though it can be used. If you modify the steering rack, it must be mounted exactly where the OEM steering rack was located.
Before Ordering
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 there are 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 confirm whether it is possible to install on Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you 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, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. There may be confusing expressions, so 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, 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.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please inquire about delivery dates in advance. Please note that all products are transported by air. They are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
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 cannot provide strength calculation documents or similar paperwork for this purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of the product. Because 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 only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
