WiseFab - BMW G20 G42 Front Drift Angle Lock Kit

• 65+ degrees of lock, parallel steering.
  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.
• Adjustable lock stopper.
• One piece lower control arm desing with easy caster adjustment.
  Lower links are replaced with one arm. Drifting with higher steering angle the stiffness and packaging would become an issue. Therefore lower one piece arm is used.
• Higher roll center (RC).
  On Wisefab knuckle, joints are dropped, 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. 

Kit includes:

• Adjustable coilover upper mounts, Formula Drift compliance.
• Knuckles with hardware.
• Lower control arms.
• Assembeled tie rods.
• Coilover adapter sleeve.
• Installation guide.

 Other components, packaging and clearance.

• This kit requires wheel bearings and hubs from E9X models (5x120 pattern)
  This Kit requires brake callipers and rotors from E9X or F-series
• This kit assumes coilovers, to have enough clearance. 
• Dependent on rim width and ET, wider fenders or fender flares would be needed.
• Minimum rim diameter is 18”.
