Wisefab BMW e9x lock kit can be fitted on a variety of BMW models. E90, E91, E92, E81, E82, E87, E88 M and non-M. Brackets included to fit M brake caliper. Either M or non-M front coilovers would work with Wisefab E90 knuckle. All the metal components on Wisefab E90 front suspension are from high strength steel, including sheet metal components, tubes, tube ends and rod end housings. Rod ends and spherical bearings are used, no rubber bushings.
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: -4.5 +/-0.5
Caster: 6 +/-0.5
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 design
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
Original wheel speed sensor (ABS sensor) can be used
Kit includes:
Adjustable coilover upper mounts, Formula Drift compliance
Knuckles with hardware
Lower control arms
Assembled tie rods
Brake adapters for M model brakes
45mm coilover adapter sleeve
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 do not need to be 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
