Wisefab Front Drift Angle Lock Kit, BMW E9X M3

Features:

65 degrees of lock, parallel steering
Easily tune your steering geometry towards positive or negative Ackermann in just a few minutes, even trackside, without affecting the alignment. The Ackermann adjustment kit is included.

Adjustable lock stopper

One piece lower control arm design
To accommodate higher steering angles required for drifting, lower links are replaced with a single arm. This choice prevents issues with stiffness and packaging that may arise with increased steering angles.

Higher roll center (RC)
The Wisefab knuckle features dropped joints, raising the front RC on lowered cars. This increases roll stiffness, allowing for the removal of the front anti-roll bar (sway bar). High lock angles make it challenging to package the front anti-roll bar effectively.

Improved camber control and minimal bump steer with high steering angles
In drift cars, dynamic camber and bump steer play a crucial role compared to static settings. Wisefab kinematics guarantee excellent front grip through optimized camber and minimal bump steer across the entire steering range.

Steering jacking control
In drifting, as the steering angle increases significantly, so does the jacking effect, even when the geometry remains the same. This can potentially pose a problem. However, Wisefab has adjusted the geometry to mitigate any handling issues arising from this effect.

Consistent and predictable self-alignment torque
Caster alone isn't the sole crucial factor for ensuring ample self-alignment torque, particularly at high degrees of lock. It's the collective interaction of various parameters that ensures consistent trail and self-alignment torque. Wisefab's setup ensures that the steering wheel consistently aligns with the direction of movement and doesn't become stuck at full lock.

Original wheelspeed sensor (ABS sensor) can be used.

Kit Contents:

• Adjustable coilover upper mounts, Formula Drift compliance.
• Knuckles with hardware.
• Lower control arms.
• Assembeled tie rods.
• Brake adapters for M model brakes.
• 45mm coilover adapter sleeve.
• Installation guide.

Notes:

• This kit assumes coilovers to have enough clearance. 
• Ride height is designed to be ~80 mm 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
