Legendary Toyota Supra with double wishbone suspension enables 65 degrees of usable lock with adjustable Ackermann settings on Wisefab Supra suspension kit. While providing over 60 degrees of lock, this kit is engineered and tested to optimize a lot of other parameters that make a difference in handling and performance. Very easy to install and adjust. Wisefab has engineered an adjustable shock absorber motion ration on the lower control arm. Set your desired toe in and enjoy. Adjust the stiffness while not changing the ride height. All the parts in the lock kit are provided as spare parts.

Here is our recommended alignment parameters:
Toe in/out: If Ackermann is 0 or negative then toe is 2mm out. If Ackermann is positive then toe is 0
Camber: -3,3 +/-0,3
Caster: 3 +/-0,3
- 65 degrees of lock, parallel steering.
Both wheels turn the same angle. You could tune your steering geometry either towards positive or negative Ackermann in just a few minutes even at trackside without messing up an alignment.
Ackermann adjustment kit included.
- Higher roll center (RC).
On Wisefab knuckle, both joints have lowered about 60mm, which brings the front RC up on lowered car, providing higher roll stiffness and letting to remove the front anti roll bar (sway bar) that is quite difficult to package with that high lock angles.
- Very good camber control and minimal bump steer with high steering angles.
On drift cars the dynamic camber and bump steer is much more important than static. With our kinematics we have assured that the camber would provide very good front grip and bump steer is minimal at all the range of steering.
- Steering jacking control.
During drifting, when steering angle is much bigger, jacking is also bigger, even with the same geometry and it could become a problem. We have changed the geometry that it doesn’t cause any handling issues.
- Consistent and predictable self-alignment torque.
Caster is not the only important parameter to provide sufficient self-alignment torque especially at high lock. It’s the combination of different parameters to maintain consistent trail and self-alignment torque. With our setup the steering wheel turns always to the direction of movement and doesn’t get stuck at full lock.
- Adjustable spring and shock absorber motion ratio.
The shock lower bracket has 3 attachment possibilities, which allows to change suspension stiffness and handling very quickly without changing the spring and messing up ride heights.
