Suspension Secrets Handling Pack 3 (Track) - BMW E90 / E92 M3

Suspension Secrets Handling Pack 3 (Track) – BMW E90 / E92 M3

Transform your BMW E90 or E92 M3 into a fully track-focused chassis with Suspension Secrets Handling Pack 3.

Designed for serious circuit use and semi-slick trackday tyres, this package combines the suspension and geometry upgrades required to substantially increase grip, stability and chassis precision on track.

The factory E9x M3 is an excellent performance platform, but the standard suspension still uses a number of compliant rubber bushes and offers relatively limited geometry adjustment. Under sustained track loads, these components can flex and allow the wheel alignment to move away from the settings chosen during setup.

Handling Pack 3 addresses these limitations with adjustable arms, solid bushes, uprated anti-roll bars and track-focused suspension components to create a much more direct and consistent chassis.

• Suspension Secrets Solid Rear Subframe Bushes

Together, these components address suspension geometry, bush compliance, anti-roll bar control and rear axle stability.

Adjustable Front & Rear Drop Links

Changing ride height can alter the operating position of the anti-roll bars and introduce unwanted preload.

Adjustable drop links allow the front and rear anti-roll bars to be correctly positioned around the final suspension setup.

Potential benefits include:

• Reduced anti-roll bar preload
• Improved left-to-right handling consistency
• Better anti-roll bar operation
• More balanced suspension behaviour

They are also particularly useful for cars that have been corner weighted.

Adjustable Rear Toe Arms

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

The standard rear suspension can allow toe settings to move dynamically under load.

Suspension Secrets Adjustable Rear Toe Arms provide greater control over rear alignment while reducing unwanted deflection.

Potential benefits include:

• Improved rear stability
• Greater traction
• More consistent geometry
• Better high-speed confidence
• Improved acceleration response

Off-Centre Caster Control Arm Bushes

The off-centre caster bushes reduce unwanted front suspension compliance while also increasing geometry control.

Additional positive caster can help provide:

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

This becomes especially useful on track cars running high-grip tyres.

H&R Anti-Roll Bars

H&R Anti-Roll Bars are included to provide greater control over chassis roll and handling balance.

Compared with the standard anti-roll bars, the uprated setup can help:

• Reduce body roll
• Improve response during direction changes
• Increase chassis precision
• Improve front-to-rear balance

Anti-roll bar setup should be considered as part of the complete suspension package.

Adjustable Rear Camber Arms

Rear camber becomes increasingly important as cornering loads and tyre grip increase.

Suspension Secrets Adjustable Rear Camber Arms provide greater control over rear alignment and allow more aggressive track settings to be used.

This can help improve:

• Mid-corner grip
• Tyre contact
• Rear axle stability
• Overall chassis balance

Adjustable Rear Upper Third Links

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

When more aggressive rear camber is introduced, these links can operate at less favourable angles or become loaded.

Adjustable upper third links allow the rear suspension to accommodate greater geometry changes while reducing unwanted binding.

Potential benefits include:

• Greater rear camber range
• Reduced joint and bearing binding
• Improved suspension freedom
• More consistent rear geometry

Adjustable Rear Traction Arms

The adjustable rear traction arms help control rear hub movement under acceleration, braking and cornering loads.

Reducing the compliance of the factory arrangement can improve:

• Rear axle response
• Straight-line stability
• Corner-exit traction
• Geometry consistency
• Throttle response through the chassis

Solid Rear Control Arm Bushes

The standard rear control arm bushes can flex significantly under heavy cornering loads.

This can allow both camber and toe to change dynamically.

Suspension Secrets Solid Rear Control Arm Bushes reduce this unwanted movement, helping keep the rear suspension more consistent.

Potential benefits include:

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

Solid Rear Subframe Bushes

The rear subframe is another area where factory rubber compliance can allow unwanted movement.

Solid rear subframe bushes reduce the movement between the rear subframe and chassis.

This can create a more direct connection between the rear suspension and body shell.

Potential benefits include:

• Improved rear axle precision
• Greater chassis response
• More consistent geometry
• Better feedback
• Improved stability under load

Reduced Suspension Flex

A key objective of Handling Pack 3 is to remove unwanted movement from the standard suspension system.

Replacing compliant rubber components with solid or motorsport-oriented alternatives helps the suspension maintain the intended geometry more accurately under load.

This creates a more direct relationship between:

• Tyres
• Suspension
• Chassis
• Driver inputs

Improved Mid-Corner Grip

Keeping the wheels closer to the chosen alignment settings during sustained cornering allows the tyres to work more effectively.

When correctly configured, this can provide:

• Increased sustained grip
• Better tyre contact
• Greater chassis balance
• More predictable handling at the limit

Improved High-Speed Stability

At higher speeds, small suspension movements can have a noticeable effect on confidence and consistency.

Reducing compliance and increasing geometry control helps the M3 feel more settled during:

• High-speed cornering
• Direction changes
• Heavy braking
• Fast transitions

Improved Braking Stability

Heavy braking places substantial load through the suspension and rear subframe.

Rubber bushes can deform and allow the geometry to shift.

Reducing this movement helps create a more stable braking platform and can improve steering confidence under hard deceleration.

Improved Steering Feel

The combination of increased caster, reduced front suspension compliance and improved chassis stiffness can provide a more communicative front axle.

Potential improvements include:

• Sharper turn-in
• Increased steering precision
• Greater front tyre feedback
• Improved confidence at speed

Designed for Semi-Slick Tyres

Handling Pack 3 is particularly well suited to E9x M3s running semi-slick trackday tyres.

Higher-grip tyres generate significantly greater suspension loads than conventional road tyres.

This makes geometry control and bush stiffness increasingly important when trying to make full use of the available grip.

Track-Focused Package

Handling Pack 3 sits above the Fast Road and Clubsport packages in terms of focus.

It is particularly suited to:

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

Works Best With Coilovers

Coilovers are not included within the RCC Handling Pack.

However, Handling Pack 3 is intended to work alongside a suitable track-focused coilover system.

A quality coilover setup provides control over:

• Ride height
• Damping
• Body control
• Chassis response

Combined with the geometry, anti-roll bar and bush upgrades in Handling Pack 3, this creates the foundation for a serious E9x M3 track setup.

NVH & Road Use

Handling Pack 3 deliberately removes a significant amount of factory suspension compliance.

Because solid bushes and more rigid suspension components are used, increased noise, vibration and harshness should be expected.

Road refinement is not the priority of this package.

This is intended primarily for track-focused cars where chassis precision and consistency are more important than factory comfort levels.

Professional Installation Required

Handling Pack 3 contains multiple adjustable and solid-mounted suspension components and should be installed by an experienced performance workshop.

After installation, the vehicle should receive:

• Full suspension inspection
• Anti-roll bar setup
• Camber adjustment
• Rear toe adjustment
• Traction arm setup
• Subframe inspection
• Full wheel alignment
• Fastener checks

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

For serious circuit use, setup by a specialist familiar with BMW E9x M3 track geometry is strongly recommended.
