BMW F20
BMW F21
BMW F22

Here is our recommended alignment parameters:
Toe in/out: Toe in 3-10mm per side
Camber: -0.5 +/-0,5


  • Revised kinematics, not just dropped knuckle. 
    If the focus is more towards performance, then the car can act better with lowered ride height, but then the factory designed kinematics wouldn't work as it supposed to. The kit would give a good kinematics with lowered car - higher roll center, , revised cambergain, anti-squat and bumpsteer for maximum grip.
  • Easy camber adjustment.
    As the top links are straight tubular type, then camber can be adjusted simply by changing their length.
  • Bump steer adjustment.
    Possibility to adjust bump steer by changing rod end location in a slot.
  • Anti-squat adjustment possibility.
    Possibility to adjust anti-squat by changing the top forward link height on upright. It can be done in less than 10 minutes at the trackside. Lowering link would increase anti-squat, raising it would decrease anti-squat.
  • Original wheelspeed sensor (ABS sensor) can be used.
  • Only takes either M model or 336mm or bigger brake discs.
    Smaller brakes will not fit.
  • Wheel bearing size should be 45x85x41

Kit includes:

  • Pre-set suspension links.
  • Uprights with hardware.
  • Subframe bushings with sperical bearings.

 

Other components

  • This kit assumes lower (shorter) springs or coilovers to lower the car.

Wisefab Nissan 240sx
"’We started working together with Wisefab back in 2014 when we launched our Falken Tyres Nissan 240sx for European competition. Since then, we have enjoyed working closely with the engineers at Wisefab testing new products before going into production and have had a lot of success winning multiple championship worldwide. Thank you to everyone at Wisefab for believing in us and producing such top-quality products."
Nissan 240sx Drift
“When I first installed a Wisefab lock kit it truly opened the door for some more aggressive driving style. I quickly began to expect nothing less than the massive angle and performance that Wisefab provides and installed a lock kit on all (4) of my Nissan 240sx that I currently drift. Also, after testing what I though was a very competitive rear suspension solution against the latest Wisefab rear kit, I was blown away with the apparent grip gain the rear Wisefab kit yielded. I am so thankful that Wisefab has poured so much effort into creating a bolt on suspension solution that transforms a Nissan 240sx into what I believe is still the most competitive drift chassis in the world."
Nissan 240sx Lock kit
"I love the Wisefab suspension kits used on my competition and demo vehicles, they provide all the angle and grip we love along with the strength and durability we need to compete with the best!"
Toyota 86 Drift
"I wouldn't have half the results! Only by running Wisefab in my Toyota 86 it just makes the car handle so good and let's me adjust set up pretty easy which is a massive help going from track to track!"
