The legendary Toyota Supra with double wishbone suspension enables 65 degrees of lock with the adjustable Ackerman settings of the Wisefab Supra suspension kit. This kit is designed and tested to optimize many other parameters that make a difference in handling and performance while providing over 60 degrees of lock. It is very easy to install and adjust. Wisefab has designed an adjustable shock absorber motion ratio on the lower control arm. Simply set your preferred toe and enjoy. Adjust stiffness without changing the ride height. All parts of the lock kit are provided as spare parts.

Recommended alignment parameters are as follows:
Toe In/Out: If Ackerman is 0 or negative, toe is 2mm out. If Ackerman is positive, toe is 0
Camber: -3,3 +/-0,3
Caster: 3 +/-0,3
- 65 degrees of lock, parallel steering.
Both wheels rotate at the same angle. You can adjust the steering geometry in the plus or minus Ackerman direction in just a few minutes, even trackside, without disturbing the alignment.
Ackerman adjustment kit included. - Higher roll center (RC).
With Wisefab knuckles, both joints are lowered by approximately 60 mm, which raises the front RC when lowering the ride height, improving roll stiffness and allowing you to remove the front anti-roll bar (sway bar), which is very difficult to package at high lock angles. - Extremely good camber control and minimal bump steer even at high steering angles.
In drift cars, dynamic camber control and bump steer are much more important than static camber control. Our kinematics ensure that the camber provides excellent front grip and that bump steer is minimized across the entire steering range. - Steering jacking control.
During drifting, as the steering angle increases, jacking also increases even with the same geometry, which can become a problem. We have modified the geometry to ensure that handling issues do not occur. - Consistent and predictable self-aligning torque.
Caster is not the only important parameter for providing sufficient self-aligning torque, especially at high lock. It is the combination of various parameters to maintain consistent trail and self-aligning torque. With this setup, the steering wheel will always rotate in the direction of travel and will not get stuck at full lock. - Adjustable motion ratio for springs and shock absorbers.
The shock lower bracket has three mounting options, allowing you to quickly change suspension stiffness and handling without changing springs or ride height.
Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya 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 Confirmation of Fitment
As all product databases are based on North American vehicles (USDM), please check whether installation on Japanese vehicles (JDM) is possible before ordering. (If you are unsure whether the listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming fitment, 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, this does not necessarily mean they fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping fees are paid at the time of settlement. An estimate of the shipping cost will be calculated automatically 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 amount calculated by the automatic shipping system and the actual shipping cost. In that case, we will contact you individually via email.
All products are generally 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 the delivery date. Note that all products are transported by air freight. They will not be shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please note that all products we handle are basically designed and manufactured outside of Japan. They do not comply with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation sheets or similar documents for the Japanese inspection system. 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 of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. We will only provide returns, refunds, or replacements for products with shipping damage, defective products, or products different from your order if you contact us within 7 days of receipt. Please understand that for products sold through us, we will handle warranty-related matters "exclusively through us." Please note that we do not handle matters through other companies or agents located within Japan.
