Wisefab Scion FRS / Subaru BRZ / Toyota GT86 Lock Kit + Spares

Scion FRS, Toyota GT86 and Subaru BRZ all have the same chassis. Wisefab has engineered a light weight super strong billet knuckle and lower control arm. Also relocated and replaced OEM electric steering rack with a hydraulic steering rack for a better response and feedback from the road in racing. Kinematics have been revised for maximum sideways performance with adjustable Ackermann settings. Nissan S-Chassis hydraulic steering rack ( 50mm outer diameter ) is needed to be used with the kit to replace the original electric power steering. S-Chassis steering rack attachment/crossmember insert along with crossmember supports are included in the kit. To modify the crossmember some DIY cutting and welding needs to be done.

Here is our recommended alignment parameters:
Toe in/out: 0
Camber: -6
Caster: 5

  • 62 degrees of lock, parallel steering
    You can tune your steering geometry towards positive Ackermann in just a few minutes even at trackside without messing up the alignment. Ackermann adjustment is included in the kit
  • 7 kg of weight reduction
    While still maintaining the required strength and stiffness
  • 7075-T6 aluminium
    Billet CNC knuckles and arms with optimized design and all double shear connections provide low weight and high strength
  • CrMo rod ends and sphericals
  • Higher roll center (RC)
    With our knuckle, the ball joint is lowered, which brings the front RC up on a lowered car, providing higher roll stiffness. This allows to remove the front anti roll-bar (sway bar) that is quite difficult to package with high lock angles
  • 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 will provide very good front grip and bump steer is minimal throughout the steering range
  • Steering jacking control
    During drifting, when steering angle is increased, jacking is also bigger, even with the same geometry it could become a problem. We have changed the geometry in a way that 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

Kit includes:

  • Pre-set lower control arms
  • Knuckles with hardware
  • Assembled tie rods
  • Pre-set coilover upper mounts
  • Rack relocating kit
  • Crossmember supports
  • Installation guide

 Other information:

  • This kit assumes coilovers for enough clearance
  • Dependent on rim width and ET, wider fenders or fender flares are needed
  • Due to extremely wide engine bay on Subaru BRZ, we recommend using tires no bigger than 605mm (215/40R17, 225/40R17, 215/35R18, 225/35R18)
  • With tire diameter up to 635mm (215/45R17, 225/45R17, 235/40R17, 225/40R18 etc) and lowered ride height the inner wheel wells need to be slightly modified
  • Minimum rim size is 17“, but we recommend using 18“
  • Recommended backspacing is 135-140mm (7“ ET45; 8“ ET35; 9“ ET25). If ET is smaller, then wheels stay more outwards, if ET is bigger, then spacers need to be used
  • Original wheel speed sensor can be used
