The first-generation Lexus IS, also known as the Toyota Altezza, has been around for decades. Despite this, the popular chassis is still widely used by many car enthusiasts around the world due to its relatively light weight, good handling, and drift-friendly wheelbase. In response to customer demand, we decided to develop a PRO-level drift angle kit. This product has been tested by top-tier drivers in Europe and the United States, and we are finally pleased to offer it to our customers.
All metal components of the Wisefab Lexus IS front suspension, including sheet metal parts, tubes, tube ends, and rod ends, are made of high-tensile steel. All parts are manufactured and assembled at our production facility in Europe.
This kit requires overfenders. Want to see how the Wisefab kit fits your car? Please check the Fitment Calculator.
Recommended alignment parameters:
Toe in/out: 2mm out if Ackermann is 0 or negative. 0 if Ackermann is positive
Camber: -4 (+-0.5)
Caster: 5.4 (+-0.5)
- 65 degrees or more of steering angle, parallel steering, and adjustable lock stoppers. You can adjust the steering geometry to positive or negative Ackermann in just a few minutes, even trackside, without disturbing the alignment. Ackermann adjustment kit included.
- Steering rack repositioned to improve the Ackermann curve, resulting in a more user-friendly angle, better feel, and precise handling. Repositioning the steering rack eliminates the need for rack offset spacers, allowing for higher rigidity and more precise handling.
- Easily adjustable integrated lower control arm design.
The lower links are replaced with one arm. Rigidity and packaging become issues when drifting with high steering angles. Therefore, a lower integrated control arm is used. Our "double adjuster" allows you to fine-tune the setup easily and quickly. - Unique "upside-down" upper control arm design provides more clearance for suspension components, avoiding interference with the chassis. It also features a "double adjuster" for convenient camber and caster adjustment.
- Higher roll center (RC).
With the Wisefab knuckle add-on, the joints are dropped, raising the front RC when the vehicle is lowered, which increases roll stiffness and improves drivability. - Excellent camber control and minimal bump steer even at high steering angles.
In drift cars, 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 jacking control.
During drifting, jacking can increase at higher steering angles, even with the same geometry, which can become a problem. We have modified the geometry to prevent handling issues. - Consistent and predictable self-aligning torque.
Caster is not the only critical parameter for providing sufficient self-aligning torque, especially at high angles. It is the combination of various parameters that maintains consistent trail and self-aligning torque. In our setup, the steering wheel always turns in the direction of travel and does not get stuck at full lock. - Genuine wheel speed sensors (ABS sensors) can be used.

Before placing your order
〇 About 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 will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of compatibility
Our product database is based on North American vehicles (USDM), so please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether 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.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese models 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. An estimate for shipping costs will be calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may sometimes differ significantly from 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 order with enough time. If you are in a hurry, please contact us to confirm the delivery date in advance. All products are shipped via air freight. They are never shipped by sea freight.
○ Regarding Japanese vehicle inspection (Shaken) compatibility
Essentially, all products handled by our company are designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese vehicle inspection (Shaken) system" in any way, and we cannot provide strength calculation documents for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-public roads," 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 shipping damage to the packaging box or the product. We will provide returns, refunds, or replacement exchanges only if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or items different from your order. Please understand that for products sold through our company, warranty support will be handled "only through our company." Please note that we do not handle support through other companies or agencies located in Japan.
