The version 2 Wisefab Nissan S14 and S15 angle kit with rack offset spacers has two major upgrades.
The knuckle has been designed to allow more suspension travel.
The lower control arm has been redesigned for more convenient alignment setup.
The result was more grip at the front and more precise steering. 

Benefits of Wisefab S Chassis suspension kit:

• More usable lock.
  65+ degrees of lock, better feel and precise handling. 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.
• Less sensitive steering.
  Increased steering ratio for smooth handling.
• More suspension travel.
  Less interference risk at full droop. Longstroke coilover kits can be used.
• Lighter and stronger.
  Optimized design in combination with high strength steel is used.
• Higher roll center (RC).
  On Wisefab knuckle, the ball joint is lowered 60mm, 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.
• Adjustable camber and caster with adjustable doubleplates.
• Adjustable lock stopper.
• One piece lower control arm desing. 
  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.
• 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.
• Assembled tie rods.
• Rack offset kit.
• Rack installation guide.
• Installation guide.

Other components, packaging and clearance.

• This kit assumes coilovers to have enough clearance.
• Dependent on rim width and ET, wider fenders or fender flares would be needed.
• 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.

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.
