Ford Mustang S550 Front Steering Kit

Installation Manual

Ackermann angle explanation

Unleash the full drifting potential of your Ford Mustang S550 with the Wisefab kit, the ultimate upgrade for both professional and amateur drivers. Precision engineered and crafted from the highest quality materials, this kit is designed to enhance your drifting experience with increased steering angle, superior car control, and professional-grade performance and quality.

This kit is designed to be used with the S550 steering rack, but for those looking for maximum performance and more precise steering we also offer an S197 hydraulic steering rack conversion kit.

65 degrees of locking, parallel steering
Adjust steering geometry to positive or negative Ackermann in minutes, even on the trackside, without compromising alignment. Ackermann adjustment kit included.

Adjustable locking stops

High resistance drift specific drop knuckles
Improved kinematics and integrated camber adjustment.

One-piece lower control arm design with quick wheel adjustment
The lower control arm features a built-in quick wheel adjuster that is easy to use.

Built-in roll center (RC) correction.
With our ball joint the joints are lowered: this raises the front roll centre, providing greater roll stiffness and allowing the removal of the front anti-roll bar (sway bar) which is quite difficult to fit at more extreme locking angles.

Precise camber control and minimal bump-steer at high steering angles
On drift cars, dynamic camber and bump steer are much more important than static camber. With our kinematics, we designed camber to provide great front end grip and bump steer to be minimal throughout the steering range.

Steering lift control
During drifting, when the steering angle is greater, the jacking is also more extreme. Our design has modified the geometry to address these handling issues.

Constant and predictable self-aligning torque
Caster is not the only important parameter to provide sufficient self-aligning torque, especially with high lockup: there is a combination of several parameters to maintain a constant trail and self-aligning torque. With our setup the steering wheel moves in the direction of wheel movement and does not lock at full lock.

The kit includes:

• Upper coilover mounts (FD compatible)
  
• Knuckles with hardware
  
• Lower control arms
  
• Assembled tie rods
  
• Installation Guide
  
• Other components, packaging and clearance.

This kit requires coilovers for clearance and height adjustment.
Depending on wheel width and ET, wider or flared fenders may be required.
The minimum wheel diameter is 17" (some 17" wheels may not fit).
For the wheel speed sensor use Magnaride or Shelby speed sensors, part number JR3Z-2C205-B and JR3Z-2C204-B respectively.
For wheel bearings use part number FR3Z-1104-F (Shelby GT350/Magneride equipped chassis) or part number FR3Z-1109-A (Shelby GT500, includes extra long studs). Alternatively, Nissan 370z wheel bearings can be used with the supplied mounting kit (wheel speed sensor will not work with 370z option).
Recommended alignment specifications.

Camber: -4⁰ Caster: 6⁰
Convergence: If Ackerman is 0 or negative, use a convergence of 2 mm, if Ackerman is positive, use a convergence of 0 mm.
Front track: 80mm wider on each side than OEM, here you can calculate the exact fitment of the mudguard on the wheel.
