The Scion FR-S, Toyota GT86, and Subaru BRZ all share the same chassis. Wisefab has designed lightweight and ultra-strong billet knuckles and lower control arms. We have also relocated and replaced the OEM electric steering rack with a hydraulic steering rack to improve response and feedback from the road surface during racing. The kinematics have been revised to maximize lateral performance with adjustable Ackermann settings. A Nissan S-chassis hydraulic steering rack (50mm outer diameter) is required to replace the stock electric power steering. S-chassis steering rack attachments/crossmember inserts and crossmember supports are included in the kit. Modifying the crossmember requires DIY cutting and welding.

Recommended alignment parameters are as follows:
Toe: 0
Camber: -6
Caster: 5
-
62-degree lock, parallel steering
You can adjust the steering geometry towards positive Ackermann in just a few minutes trackside without disturbing the alignment. Ackermann adjustment is included in the kit. -
7 kg weight reduction
While maintaining the necessary strength and rigidity. -
7075-T6 aluminum
Billet CNC knuckles and arms with an optimized design, along with all double-shear connections, achieve both low weight and high strength. - Uses CrMo rod ends and sphericals instead of OEM bushings
-
High roll center (RC)
Using our knuckles allows the ball joint to sit lower, raising the front RC on lowered cars and providing higher roll stiffness. This allows for the removal of the front anti-roll bar (stabilizer), which is often difficult to package with high lock angles. -
Excellent camber control and minimal bump steer at high steering angles
For a drift car, dynamic camber control and bump steer are far more important than static camber control. Our kinematics ensure that the camber provides excellent front grip and that bump steer is minimized throughout the entire steering range. -
Steering jacking control
When drifting, jacking increases at high steering angles, which can be problematic even with standard geometry. We have modified the geometry in a way that avoids operational issues. -
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 a 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.

- Installation guide
Other information:
- This kit assumes the use of coilovers with sufficient clearance
- Depending on rim width and ET, wider fenders or fender flares will be required.
- The Subaru BRZ engine bay is very wide, so we recommend using tires 605mm or smaller (215/40R17, 225/40R17, 215/35R18, 225/35R18)
- If the tire diameter is up to 635mm (e.g., 215/45R17, 225/45R17, 235/40R17, 225/40R18) and the car is lowered, slight modification to the inner wheel wells will be necessary.
- Minimum rim size is 17 inches, but 18 inches is recommended
- Recommended backspacing is 135-140mm (7" ET45, 8" ET35, 9" ET25). If the ET is smaller, the wheel will sit further outward; if the ET is larger, spacers will be required.
- OEM wheel speed sensors can be used
Before ordering
○ Regarding import consumption tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
○ Checking compatibility
As our entire product database is based on North American vehicles (USDM), please confirm the compatibility for Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to investigate.)
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 model on our top page, it does not guarantee that 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 delivery
Shipping costs are paid at the time of payment. 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.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please allow sufficient 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 never shipped by sea freight.
○ Regarding Japanese vehicle inspection (Shaken) compliance
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection regulations," and we cannot provide strength evaluation documents or similar paperwork for such purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding warranties
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to packaging or products. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
