KW height-adjustable springs kit (Lowering springs) - BMW 2 Series G87 M2 (2023+)

KW Height Adjustable Spring Kit – BMW G87 M2

The KW Height Adjustable Spring Kit for the BMW G87 M2 is designed for drivers who want to lower their M2 while retaining the factory dampers and Adaptive M Suspension functionality.

Unlike conventional lowering springs, the KW HAS system provides continuously adjustable ride height, allowing the stance of the G87 M2 to be fine-tuned within KW’s tested adjustment range.

Using vehicle-specific springs, threaded height-adjustment components and matched supporting hardware, the kit provides a more flexible alternative to fixed lowering springs while retaining the sophisticated factory electronic damping system.

Why choose the KW HAS Kit for your BMW G87 M2?

The G87 M2 comes equipped with an advanced factory suspension system, and not every owner wants to replace it with a complete set of coilovers.

The KW Height Adjustable Spring Kit provides an alternative.

It allows the car to be lowered and the stance adjusted while continuing to use the original BMW dampers.

For owners who value the factory adaptive suspension but want a lower ride height and more purposeful appearance, the KW HAS kit offers an excellent middle ground between conventional lowering springs and complete coilovers.

KW developed the springs specifically around the original suspension dampers and wheel loads of the G87 M2, allowing the standard electronic suspension system to remain operational.

Retains Factory Adaptive Suspension

One of the biggest advantages of the KW HAS system is that the original G87 M2 dampers remain in place.

The BMW Adaptive M Suspension system therefore continues to operate as intended.

This means the driver retains the ability to use the vehicle’s factory suspension modes and electronically alter the damper behaviour from inside the car.

Unlike a conventional coilover conversion, there is no need to replace the electronic dampers or install a damper cancellation kit.

For owners who use their M2 regularly on the road, retaining this factory functionality can be a major advantage.

Adjustable Ride Height

Traditional lowering springs provide a fixed reduction in ride height.

The KW HAS system adds threaded adjustment, allowing the ride height to be fine-tuned after installation.

KW’s published G87 M2 adjustment range is approximately:

• Front: 15–30mm lowering
• Rear: 5–20mm lowering

This gives owners significantly more flexibility when setting the stance of the car.

The height can be configured around factors such as:

• Wheel specification
• Tyre size
• Desired arch gap
• Road clearance
• Vehicle stance
• Suspension geometry

This makes the HAS kit particularly useful for cars running aftermarket wheels where a specific ride height may be required to achieve the desired fitment.

Vehicle-Specific Spring Development

KW does not simply use a generic lowering spring with the HAS system.

The springs are developed specifically around the characteristics of the G87 M2.

KW uses high-quality chrome-silicon steel springs with spring rates selected to work with the original dampers and vehicle axle loads.

This is particularly important on cars with electronically controlled damping because the springs need to remain compatible with the different damper characteristics available through the Adaptive M Suspension system.

BMW G87 M2 Suspension Upgrade

The G87 M2 is already an extremely capable performance car, but lowering the centre of gravity and reducing suspension movement can help provide a more purposeful chassis feel.

The KW HAS kit is particularly suitable for G87 owners looking for:

• Improved stance
• Reduced arch gap
• A lower centre of gravity
• Retention of Adaptive M Suspension
• Greater ride-height flexibility
• A road-focused suspension upgrade
• An OEM+ style setup

Because the original BMW dampers remain in place, the overall character of the factory suspension is retained more closely than with a complete coilover conversion.

KW HAS vs Conventional Lowering Springs

The main advantage of the KW HAS system over conventional lowering springs is adjustability.

Traditional lowering springs provide a predetermined reduction in ride height.

Once fitted, the height cannot normally be altered without replacing the springs.

The KW HAS system uses threaded height-adjustment components, allowing the vehicle to be raised or lowered within the approved adjustment range.

This provides much greater flexibility when setting up wheel fitment and overall stance.

KW HAS vs KW V3 Coilovers

The KW HAS and KW V3 take very different approaches.

The HAS kit:

• Retains the factory dampers
• Retains Adaptive M Suspension
• Provides adjustable ride height
• Does not add manual damping adjustment

The KW V3:

• Replaces the original dampers
• Provides independently adjustable compression and rebound damping
• Requires electronic damper deactivation on the G87 M2
• Provides significantly greater suspension tuning capability

For owners primarily looking for lowering and improved stance while keeping the factory adaptive suspension, the HAS kit is the more straightforward option.

For drivers wanting significantly greater chassis adjustment and suspension control, the V3 is the more advanced solution.

KW HAS vs KW V4 Clubsport

The difference between these two systems is even greater.

The KW HAS is primarily a road-focused lowering solution that retains the factory suspension technology.

The V4 Clubsport is a highly developed track-focused coilover system with extensive damping adjustment and geometry capability.

For a road-driven G87 M2 where factory refinement and electronic damper functionality are priorities, the HAS kit will generally be the more suitable choice.

For frequent track use, semi-slick tyres and aggressive chassis setups, a Clubsport system provides significantly greater tuning potential.

Stainless-Steel Height Adjustment

KW uses corrosion-resistant stainless-steel components within the height-adjustment system.

This is particularly beneficial on cars used throughout the year in UK conditions.

Keeping the threaded adjustment areas clean will help ensure the ride height remains adjustable over the long term.

Regular maintenance is still recommended, particularly after exposure to winter road salt.

Factory Damper Integration

Because the original dampers remain installed, the KW springs are designed to work alongside the existing BMW suspension hardware.

KW develops its spring rates around the characteristics of the factory damper system rather than treating the springs as an independent component.

This helps maintain a cohesive spring and damper combination while providing the benefits of adjustable lowering.

Road & Fast-Road Use

The KW Height Adjustable Spring Kit is particularly well suited to:

• Daily-driven BMW G87 M2 models
• Fast-road builds
• OEM+ suspension setups
• Cars retaining factory Adaptive M Suspension
• Owners wanting improved stance
• Cars running aftermarket wheels
• Drivers who do not require adjustable aftermarket dampers

For more extensive track use or advanced chassis tuning, complete coilovers may be more appropriate.

Wheel & Tyre Fitment

The ability to fine-tune ride height makes the KW HAS system particularly useful for cars running aftermarket wheel and tyre combinations.

However, lowering the vehicle reduces available clearance between the wheel, tyre and surrounding bodywork.

Correct fitment will depend on factors including:

• Wheel width
• Wheel offset
• Tyre width
• Tyre profile
• Alignment
• Selected ride height

Wheel and tyre clearance should always be checked during installation.

Professional Installation & Alignment

Professional installation is recommended for the KW HAS kit.

Once fitted and the final ride height has been selected, the vehicle should receive a full four-wheel alignment.

Lowering the car alters suspension geometry, including toe and potentially camber.

A quality alignment ensures the vehicle is correctly configured following the suspension changes and can help prevent unnecessary tyre wear.

For more performance-focused road builds, a specialist fast-road alignment may further improve steering response and chassis balance.

Maintenance

Although the KW height-adjustment components use corrosion-resistant materials, regular maintenance is still recommended.

The threaded adjustment areas should be:

• Kept clean
• Periodically inspected
• Cleared of road salt and contamination
• Checked before attempting ride-height adjustments

This helps ensure the system remains adjustable throughout its service life.
