Suspension Secrets Full Kinematics Kit - BMW E92 M3

Suspension Secrets Full Kinematics Kit – BMW E90 / E92 M3

Maximise the track performance of your BMW E90 or E92 M3 with the Suspension Secrets Full Kinematics Kit.

Designed for serious circuit-focused builds, this package replaces several key factory suspension components with fully adjustable arms and solid-mounted bush solutions to reduce unwanted compliance and provide far greater control over the chassis geometry.

The kit is intended to be installed alongside a suitable set of coilovers, creating the foundation required to unlock significantly more grip, stability and precision from the E9x M3 chassis.

Why Choose the Full Kinematics Kit?

The standard E90/E92 M3 chassis is highly capable, but factory suspension components still prioritise a degree of comfort and refinement.

For track use, rubber bushes and limited adjustment range can restrict how precisely the suspension can be set up.

The Suspension Secrets Full Kinematics Kit addresses these limitations by providing:

• Increased geometry adjustment
• Reduced unwanted suspension movement
• Improved cornering grip
• Greater rear axle stability
• Improved braking stability
• Sharper chassis response
• Better traction
• More consistent suspension 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
• 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 Rear Upper Third Link Arms

Together, these components provide substantially greater control over the front and rear suspension kinematics.

Adjustable Rear Toe Arms

The adjustable rear toe arms allow rear toe to be set more precisely than with the standard components.

Rear toe has a major influence on:

• High-speed stability
• Corner entry
• Traction
• Rear axle confidence
• Tyre behaviour

Greater adjustment also makes it easier to maintain the desired toe settings when more aggressive camber is introduced.

Adjustable Rear Camber Arms

The adjustable rear camber arms provide much greater control over rear wheel camber.

This becomes especially important on track, where the correct camber setting can help the tyre maintain a more effective contact patch through high-load corners.

Potential benefits include:

• Improved rear grip
• Better tyre utilisation
• More consistent cornering behaviour
• Greater chassis balance
• Increased setup flexibility

Adjustable Rear Traction Arms

The rear traction arms help control the position and behaviour of the rear hub under acceleration, braking and cornering loads.

Replacing the compliant factory arrangement with adjustable performance components can help provide:

• Improved acceleration response
• Greater rear axle stability
• More consistent geometry under throttle
• Improved corner-exit traction
• Better chassis feedback

Solid Rear Control Arm Bushes

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

This movement can allow camber and toe to change dynamically, reducing consistency and rear-end confidence.

The Suspension Secrets solid bush solution reduces this unwanted deflection, helping maintain more stable rear geometry.

Potential benefits include:

• Improved mid-corner grip
• Increased rear axle stability
• Better handling precision
• More predictable traction
• Improved feedback

Solid Front Offset Caster Bushes

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

Additional positive caster can help provide:

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

This helps make the front axle more responsive and communicative during hard driving.

Rear Upper Third Link Arms

The rear upper third link arms are included to support the wider range of geometry adjustment available through the other rear suspension components.

They help the rear suspension operate more effectively when more aggressive alignment settings are used.

This can contribute to:

• Greater camber range
• Reduced suspension binding
• Improved rear axle consistency
• Better compatibility with track-focused geometry

Reduced Suspension Compliance

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

Factory rubber bushes help isolate noise and vibration, but under high suspension loads they can deform and allow the wheel alignment to change dynamically.

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

Improved Mid-Corner Grip

Greater geometry control helps keep the tyres working more consistently under sustained lateral load.

When correctly configured, this can provide:

• Increased mid-corner grip
• Better tyre contact
• More predictable chassis balance
• Improved confidence at the limit

Improved Braking Stability

Heavy braking places significant load through the suspension.

Reducing bush deflection and improving geometry control can help prevent unwanted alignment changes under braking.

This can create a more stable and predictable platform when braking hard.

Improved Corner-Exit Traction

The combination of adjustable camber, toe and traction arms allows the rear axle to be configured more accurately around performance driving.

This can help improve:

• Traction under acceleration
• Corner-exit stability
• Rear tyre utilisation
• Predictability under power

Designed for Track Use

The Full Kinematics Kit is primarily intended for serious performance and track applications.

It is particularly suitable for:

• Dedicated trackday cars
• Clubsport builds
• Semi-slick tyre setups
• High-grip performance tyres
• Time-attack inspired builds
• Motorsport-focused E9x M3s

Designed to Work Alongside Coilovers

The kit is designed to be used alongside a suitable performance coilover system.

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

Together, they form the foundation of a much more track-focused E90/E92 M3 chassis.

Direct Bolt-On Upgrades

All components in the kit are designed as direct bolt-on upgrades.

No further modification to the vehicle is required for installation.

This allows the suspension components to be integrated into the existing chassis while significantly increasing adjustment and precision.

High-Quality Materials

Suspension Secrets manufactures its components using materials selected for demanding performance applications, including:

• 6082 T6 aluminium
• 303 stainless steel
• EN19T steel

These materials are used to provide a combination of:

• Strength
• Durability
• Low weight
• Long-term reliability

Designed & Manufactured in the UK

All Suspension Secrets components are designed, developed and manufactured in-house in the UK by their engineering team.

This allows the parts to be developed as a complete suspension system rather than as unrelated individual upgrades.

Lifetime Warranty

Suspension Secrets states that its products are covered by a lifetime warranty, including the bearings used within the components.

Warranty terms and conditions should be checked before purchase.

NVH Considerations

Because the Full Kinematics Kit replaces several compliant factory components with solid or motorsport-oriented alternatives, some 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 components included, professional installation is strongly recommended.

The kit should ideally be fitted by a workshop experienced with performance BMW suspension and geometry setup.

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 chassis balance
