Toyota Supra JZA80 Lock Kit
The main objective of this Wisefab Toyota Supra front suspension kit is to provide more grip on lowered car, parallel steering and more usable lock. All the metal components on Supra front suspension are from high strenght steel, including sheetmetal components, tube ends and rod end housings. Rod ends and spherical bearings are used, no rubber bushings.
- 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.
- Pre-set suspension control arms.
- Knuckles with hardware.
- Installation guide.
Other components, packaging and clearance:
- This kit assumes coilovers to have enough clearance.
- Ride height is designed to be ~80mm from front subframe to ground.
- Dependent on rim width and ET, wider fenders or fender flares would be needed.
- Inner wheel wells need to be slightly modified with tire diameter up to 635mm (215/45R17, 225/45R17, 235/40R17, 225/40R18 etc).
- Minimum rim diameter is 17”.Recommended backspacing is ~135mm (7“ ET45; 8“ ET35; 9“ ET20).
- If ET is smaller, then wheels stay more outwards, if ET is bigger, then spacers need to be used.
- The kit is designed and manufactured the way that after installation and toe adjustment it’s ready to use right away.
