Nissan Micra K11 Bump Steer Correction Kit

Designed and manufactured by GizFab, our Nissan Micra K11 Bump Steer Correction Kit is designed to correct unwanted steering geometry changes that can occur when the K11 is significantly lowered.

Lowering the vehicle alters the relationship between the steering rack, track rods and suspension arms. As the suspension moves through its travel, this altered geometry can cause the front wheels to change toe without any input from the driver, commonly known as bump steer.

Our kit provides an adjustable solution for correcting the steering geometry on lowered, fast-road and competition K11s.

What is Bump Steer?

Bump steer is a change in wheel toe caused by suspension movement rather than steering input.

Ideally, as the front suspension moves through compression and rebound, the wheel should maintain its intended steering angle as closely as possible.

However, the track rod and suspension arm each travel through their own arcs.

When the relationship between these arcs is incorrect, suspension movement can effectively push or pull on the steering arm.

The result is a change in toe as the suspension moves.

From behind the wheel, excessive bump steer can make the car feel nervous or unpredictable over:

• Bumps
• Undulations
• Kerbs
• Heavy Braking
• Compression
• Rapid Weight Transfer

Instead of the steering responding solely to the driver's input, suspension movement itself can influence the direction of the front wheels.

Why Does Lowering Affect Bump Steer?

The original K11 steering and suspension geometry was designed around the factory ride height.

When the vehicle is significantly lowered, the resting angles of the suspension arms and steering links change.

The steering linkage can then operate on a different arc relative to the suspension, potentially creating a greater change in toe as the wheel moves through its suspension travel.

Simply adjusting the conventional tracking does not necessarily correct bump steer.

Static tracking determines the wheel alignment while the vehicle is sitting at a particular position.

Bump steer concerns how that alignment changes as the suspension moves.

Our correction kit allows the steering linkage to be configured as part of properly setting up a lowered K11.

Fine-Pitch Turnbuckle Adjustment

The kit features a fine-pitch turnbuckle adjustment system, allowing extremely small changes to be made during wheel alignment.

Fine adjustment is particularly useful when setting up toe accurately, as even relatively small changes in track rod length can produce a noticeable change at the wheel.

The turnbuckle arrangement also makes adjustment considerably easier during professional suspension setup.

Motorsport-Grade FLURO Rod Ends

The kit uses motorsport-grade FLURO rod ends to provide precise articulation with minimal unwanted compliance.

Compared with a conventional rubber-bushed joint, a quality spherical rod end provides a much more direct mechanical connection, making it particularly suited to competition suspension and steering applications.

Protective weather boots are included to help shield the rod ends from dirt, moisture and road debris.

As with any motorsport spherical joint, periodic inspection and maintenance are essential.

Rod ends are service items and should be replaced if excessive play, stiffness, corrosion or damage develops.

Zinc-Plated Hardware

The supplied hardware features a zinc-plated finish to provide enhanced corrosion resistance.

As with any adjustable suspension or steering component, adjustment threads should be kept clean and periodically inspected.

⚠️ PROFESSIONAL INSTALLATION & GEOMETRY SETUP REQUIRED

This is an adjustable steering component and must be installed and set up by a suitably qualified professional.

Installation should be followed by an accurate wheel alignment.

For a proper bump steer setup, the steering geometry should ideally be checked through a representative range of suspension movement rather than relying solely on static toe measurements.

The objective is not simply to achieve the correct toe while the vehicle is stationary, but to minimise unwanted toe change as the suspension moves through compression and rebound.

Once setup is complete:

• Ensure Adequate Thread Engagement is Maintained
• Correctly Tighten All Locking Hardware
• Check Rod-End Articulation
• Check Clearance Throughout Steering Movement
• Check Clearance Throughout Suspension Travel
• Check Brake Hose & ABS Wiring Clearance
• Verify Static Wheel Alignment
• Recheck All Components After Initial Use

Important - Every Lowered Car is Different

The amount of bump steer present will depend on the individual vehicle and its complete suspension configuration.

Factors can include:

• Ride Height
• Spring & Damper Setup
• Control Arm Geometry
• Roll Centre Correction
• Wheel & Tyre Specification
• Steering Rack Position
• Suspension Travel
• Other Aftermarket Suspension Components

For this reason, there is no single adjustment position that should simply be copied from another vehicle.

The kit should be set up to suit the individual car.

Motorsport Application

This is a performance steering component developed primarily for lowered, track and competition vehicles where accurate suspension and steering geometry is a priority.

The use of spherical rod ends provides considerably less isolation than conventional factory steering joints and may result in increased steering feedback, noise and harshness.

These are normal characteristics of motorsport-style components and are not considered product defects.

12-Month Warranty*

This product is warranted to the original purchaser against defects in materials and workmanship for a period of 12 months from purchase.

Our obligation under this warranty is limited to repair or replacement, at our discretion, where inspection confirms a manufacturing or material defect.

Rod ends are mechanical joints subject to wear during normal use. The warranty does not cover normal rod-end wear, contamination, corrosion caused by inadequate maintenance or damaged weather boots, incorrect installation or adjustment, insufficient thread engagement, impact damage, modification, accident damage or misuse.

Incorrect steering geometry can significantly affect vehicle handling and safety. Professional installation, alignment and setup are strongly required.
