Suspension Secrets Full Kinematics Kit - BMW F22 M235i/M240i

Suspension Secrets Full Kinematics Kit – BMW F22 M235i / M240i

Unlock significantly greater suspension control and maximise on-track grip with the Suspension Secrets Full Kinematics Kit for the BMW F22 M235i and M240i.

Developed extensively through track testing, this comprehensive chassis package replaces several key factory suspension components with fully adjustable arms and solid-mounted bush solutions to reduce unwanted compliance and dramatically increase geometry control.

The kit is designed for serious track-focused builds where the limitations of the standard F22 suspension become increasingly apparent under high cornering, braking and acceleration loads.

When combined with a suitable coilover setup and professional geometry, the Full Kinematics Kit provides the foundation for transforming the M235i or M240i into a much more precise and capable track car.

Why Choose the Full Kinematics Kit?

The standard F22 chassis was designed around a balance of performance and road comfort, which means it relies heavily on compliant rubber bushes and offers relatively limited suspension adjustment.

For track use, these characteristics can result in:

• Unwanted suspension movement
• Dynamic camber and toe changes
• Reduced mid-corner grip
• Less predictable rear axle behaviour
• Reduced braking stability
• Limited geometry adjustment

The Full Kinematics Kit addresses these limitations with a comprehensive range of adjustable and solid-mounted components.

Key Benefits

Potential benefits include:

• Increased geometry adjustment
• Reduced suspension deflection
• Improved mid-corner grip
• Greater stability under heavy braking
• Sharper turn-in
• Improved rear axle precision
• Better traction under acceleration
• More consistent chassis behaviour
• Greater control over track-focused alignment

What's Included?

The Suspension Secrets Full Kinematics Kit includes:

• 1 pair Suspension Secrets Adjustable Rear Toe Arms
• Rear Toe Lockout Kit
• 1 pair Suspension Secrets Adjustable Rear Camber Arms
• 1 pair Suspension Secrets Adjustable Rear Traction Arms / Trailing Arms
• 1 pair Suspension Secrets Solid Rear Control Arm Bushes
• 1 pair Suspension Secrets Solid Front Offset Caster Bushes
• 1 pair Suspension Secrets Adjustable Rear Upper Third Links

Together, these components provide significantly greater control over the front and rear suspension geometry.

Adjustable Rear Toe Arms

The adjustable rear toe arms provide much greater control over rear wheel toe than the factory components.

The standard rubber-bushed toe arms can flex under hard cornering and acceleration, allowing the rear toe angle to change dynamically.

The Suspension Secrets arms help reduce this movement and provide greater adjustment range.

Potential benefits include:

• Improved rear stability
• Better traction
• More consistent toe control
• Improved high-speed confidence
• More precise alignment

Rear Toe Lockout Kit

The included toe lockout kit removes reliance on the factory eccentric adjustment system.

This allows the adjustable toe arms to provide the required alignment control and helps keep the selected setting more securely in place during demanding track use.

Adjustable Rear Camber Arms

Rear camber plays a major role in maintaining tyre contact during hard cornering.

The adjustable rear camber arms allow the rear geometry to be tailored around:

• Track use
• Ride height
• Semi-slick tyres
• Driver preference
• Desired chassis balance

Correctly configured camber can improve:

• Mid-corner grip
• Rear-end stability
• Tyre utilisation
• Cornering consistency

Adjustable Rear Traction Arms

The adjustable rear traction arms help control the position of the rear hub under acceleration and braking.

Replacing the compliant factory arrangement with a more precise adjustable component can help reduce unwanted movement.

Potential benefits include:

• Improved acceleration
• Better straight-line stability
• Reduced toe change under throttle
• More responsive rear axle behaviour
• Improved corner-exit traction

Solid Rear Control Arm Bushes

The factory rear control arm bushes can flex significantly under high suspension loads.

This movement can cause both rear camber and toe to change dynamically.

The Suspension Secrets solid bush solution reduces this unwanted movement and helps maintain more consistent geometry.

Potential benefits include:

• Increased rear axle stability
• Improved mid-corner grip
• More predictable handling
• Better rear feedback
• Greater geometry consistency

Solid Front Offset Caster Bushes

The front offset caster bushes reduce unwanted compliance in the front suspension while also allowing the caster geometry to be improved.

The offset design can increase positive caster, which may help provide:

• Improved steering feel
• Greater front-end grip
• Better high-speed stability
• Increased dynamic camber gain
• Sharper turn-in

They also provide greater flexibility when combining aggressive caster settings with adjustable top mounts.

Adjustable Rear Upper Third Links

The standard rear upper third links are fixed-length components.

When more aggressive rear camber is introduced, this can place unwanted load through the associated joints and bearings.

Adjustable upper third links allow the rear suspension to accommodate a wider range of geometry settings while reducing binding.

Potential benefits include:

• Greater rear camber range
• Reduced joint and bearing binding
• Improved suspension freedom
• Better rear axle consistency
• Improved compatibility with aggressive track geometry

Reduced Suspension Compliance

One of the main objectives of the Full Kinematics Kit is to remove key areas of rubber compliance from the suspension.

Factory rubber bushes are useful for reducing road noise and vibration, but they also allow the suspension geometry to move under load.

Reducing this movement helps keep the wheels closer to the alignment settings chosen during setup.

Improved Mid-Corner Grip

Keeping camber and toe more consistent under load allows the tyres to work more effectively through high-load corners.

When correctly configured, this can provide:

• Greater sustained cornering grip
• Improved tyre contact
• More predictable handling
• Better chassis balance

Improved Braking Stability

Heavy braking places substantial load through the suspension.

Compliant bushes can deform and allow unwanted alignment changes.

Reducing this movement can help create a more stable and confidence-inspiring platform under hard braking.

Sharper Turn-In

Reducing front suspension compliance and increasing geometry control can create a more immediate response to steering inputs.

This can provide:

• Sharper turn-in
• Better front-end confidence
• More precise steering
• Improved feedback

Extensive Geometry Control

The Full Kinematics Kit gives a geometry specialist far more control over the F22 chassis.

This allows the car to be set up around factors such as:

• Semi-slick tyres
• Track use
• Ride height
• Coilover specification
• Driver preference
• Desired front-to-rear balance

Designed for Track Use

This package is primarily intended for performance-focused and track applications.

It is particularly suitable for:

• Dedicated trackday cars
• Clubsport builds
• Semi-slick tyre setups
• Time-attack inspired builds
• High-grip performance cars

Designed to Work Alongside Coilovers

The Full Kinematics Kit is designed to be installed alongside a suitable performance coilover system.

The coilovers control spring and damper behaviour, while the kinematics components provide the geometry adjustment and reduced suspension compliance required to make full use of the upgraded suspension.

Together, they form the foundation of a serious F22 track setup.

NVH Considerations

Because this kit replaces several compliant factory rubber components with solid or motorsport-oriented joints, an increase in noise, vibration and harshness should be expected.

This is a track-focused package intended for drivers who prioritise suspension precision and geometry control over factory levels of refinement.

Professional Installation Required

Due to the number of adjustable suspension components included, professional installation is strongly recommended.

The kit should ideally be fitted by a workshop familiar with performance BMW suspension geometry.

Track Geometry Setup Essential

A full performance geometry setup is essential after installation.

The final settings should be tailored around:

• Tyre specification
• Ride height
• Coilover setup
• Track use
• Driver preference
• Desired handling balance

For serious circuit use, setup by a specialist familiar with BMW F22 geometry is strongly recommended.
