Suspension Secrets Full Kinematics Kit - BMW F80 M3/F82 M4

Suspension Secrets Full Kinematics Kit – BMW F80 M3 / F82 M4

Unlock the true potential of your BMW F80 M3 or F82 M4 with the Suspension Secrets Full Kinematics Kit.

Designed for serious track-focused builds, this package combines fully adjustable suspension arms, lockout hardware and solid bush upgrades to dramatically increase geometry control and reduce unwanted suspension movement.

The result is a more precise, stable and predictable chassis that allows the tyres and dampers to work more effectively under high cornering, braking and acceleration loads.

Why Choose the Full Kinematics Kit?

The factory F80 M3 and F82 M4 chassis are extremely capable, but standard suspension components still include a degree of compliance and limited geometry adjustment.

For serious track use, this can restrict how accurately the chassis can be set up and how consistently the alignment is maintained under load.

The Full Kinematics Kit addresses these limitations by providing:

• Greater suspension geometry adjustment
• Reduced unwanted compliance
• Improved rear axle stability
• Greater traction
• Increased cornering grip
• More precise handling
• Better braking stability
• Improved chassis response
• More consistent alignment under load

What's Included?

The Suspension Secrets Full Kinematics Kit includes:

• 2 x Suspension Secrets Adjustable Rear Toe Arms
• Rear Toe Lockout Kit
• 4 x Suspension Secrets Adjustable Rear Camber Arms
• Rear Camber Lockout Kit
• 2 x Suspension Secrets Adjustable Rear Traction Arms / Trailing Arms
• 2 x Suspension Secrets Solid Rear Control Arm Bushes
• 2 x Suspension Secrets Solid Front Offset Caster Bushes

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

Adjustable Rear Toe Arms

Rear toe has a major influence on stability, traction and rear axle behaviour.

The adjustable toe arms provide a greater range of adjustment while reducing unwanted movement compared with the standard arrangement.

Potential benefits include:

• Improved rear axle stability
• Greater corner-exit traction
• Better high-speed confidence
• More accurate rear alignment
• Improved response under acceleration

Rear Toe Lockout Kit

The supplied rear toe lockout kit helps remove reliance on the factory eccentric adjustment once the adjustable arms are installed.

This creates a more secure and repeatable mounting point for track-focused geometry.

Potential benefits include:

• Reduced chance of alignment movement
• More consistent toe settings
• Greater confidence during hard track use
• Improved repeatability during geometry setup

Adjustable Rear Camber Arms

The kit includes four adjustable rear camber arms, providing significantly greater control over rear wheel geometry.

This allows the rear camber to be configured more accurately around:

• Ride height
• Tyre specification
• Track use
• Driving style
• Desired chassis balance

Correct rear camber can help improve tyre contact and grip through sustained corners.

Rear Camber Lockout Kit

The supplied rear camber lockout kit allows the factory eccentric adjustment points to be secured when the adjustable camber arms are used.

This helps create a more consistent track setup and reduces the possibility of geometry changes under high loads.

Greater Rear Camber Adjustment

The additional adjustment range allows more aggressive rear geometry to be applied for track use.

Potential benefits include:

• Increased mid-corner grip
• Better tyre utilisation
• Improved rear axle balance
• Greater chassis stability
• More consistent cornering behaviour

Adjustable Rear Traction Arms

The rear traction arms help control how the rear hub behaves under acceleration and suspension compression.

Replacing the standard components with adjustable performance arms can help reduce unwanted movement and improve the relationship between throttle input and rear axle response.

Potential benefits include:

• Improved acceleration
• Greater corner-exit traction
• Better straight-line stability
• More responsive rear axle behaviour
• Improved geometry consistency

Solid Rear Control Arm Bushes

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

This movement can allow the rear geometry to change dynamically.

Suspension Secrets Solid Rear Control Arm Bushes reduce this unwanted compliance, helping keep the rear axle closer to the geometry settings chosen during alignment.

Potential benefits include:

• Improved rear stability
• Greater cornering grip
• More predictable handling
• Better rear axle feedback

Solid Front Offset Caster Bushes

The solid front offset caster bushes reduce compliance at the front axle while also increasing positive caster.

This can improve:

• Steering feel
• Front-end grip
• Turn-in response
• Braking stability
• Dynamic camber gain
• High-speed confidence

The offset design also provides greater control over front caster geometry.

Reduced Suspension Compliance

One of the main advantages of the Full Kinematics Kit is the reduction in unwanted movement through the suspension.

Rubber bushes and factory eccentric adjustments can introduce movement that allows wheel alignment to change under load.

Reducing this compliance helps the car maintain more consistent geometry during:

• Heavy braking
• Fast cornering
• Direction changes
• Hard acceleration

Improved Mid-Corner Grip

Greater camber control and reduced bush movement help the tyres maintain a more consistent relationship with the road surface.

When correctly configured, this can contribute to:

• Increased sustained grip
• Better tyre contact
• Improved chassis balance
• More predictable behaviour at the limit

Improved Corner-Exit Traction

The combination of adjustable toe, camber and traction arms allows the rear axle to be configured more accurately around high-load acceleration.

Potential benefits include:

• Better traction
• More stable power delivery
• Increased rear axle confidence
• Improved corner-exit speed potential

Improved Braking Stability

Reducing front suspension compliance helps maintain more consistent geometry during heavy braking.

This can make the car feel more settled and predictable under hard deceleration.

Increased Geometry Adjustment

The Full Kinematics Kit provides significantly greater adjustment than the standard suspension.

This allows a specialist to tailor the car around:

• Road or track use
• Semi-slick tyres
• Ride height
• Driver preference
• Circuit characteristics
• Desired front-to-rear balance

Designed for Track-Focused Builds

This kit is particularly well suited to:

• Dedicated trackday cars
• Clubsport builds
• Semi-slick tyre setups
• Time-attack inspired builds
• Heavily developed F80/F82 chassis setups

Works Best With Coilovers

While coilovers are not included, the Full Kinematics Kit is particularly effective when used alongside a suitable performance coilover system.

The coilovers control spring and damper behaviour, while the kinematics kit provides the geometry adjustment and reduced compliance required to make full use of the chassis.

6082 T6 Aluminium Construction

Suspension Secrets manufactures its suspension components from 6082 T6 aluminium.

This provides a strong and lightweight construction suited to demanding performance applications.

316 Stainless Steel Components

316 stainless steel is used throughout the relevant hardware and adjustment components for improved strength, corrosion resistance and longevity.

Lifetime Warranty

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

Warranty terms and conditions should be checked before purchase.

NVH Considerations

Because this kit includes solid-mounted suspension components and significantly reduces factory compliance, some increase in noise, vibration and harshness may be expected.

This is a performance-focused package intended primarily for drivers prioritising precision, grip and consistency over factory refinement.

Professional Installation Required

Professional installation is strongly recommended due to the number of adjustable components and lockout kits included.

The suspension should be set up by a workshop experienced with performance BMW geometry.

Performance Geometry Setup Essential

A full geometry setup is essential after installation.

The final settings should be tailored around:

• Tyre specification
• Ride height
• Coilover setup
• Road versus track use
• Driver preference
• Desired chassis balance
