KW V4 Coilovers with Top Mounts – BMW F87 M2 & M2 Competition

The KW V4 Coilovers with Top Mounts for the BMW F87 M2 and M2 Competition are an advanced suspension upgrade for drivers looking for a high level of damping control, ride-height adjustment and chassis tuning for serious fast-road and track-focused use.

Featuring independently adjustable rebound, low-speed compression and high-speed compression damping, the KW V4 provides considerably greater setup flexibility than the V3. Combined with adjustable top mounts and KW’s premium INOX-LINE stainless-steel construction, this system gives experienced drivers and suspension specialists extensive control over the behaviour of the F87 chassis.

For modified M2 and M2 Competition builds running high-grip tyres, increased power or regular track use, the V4 offers a sophisticated suspension platform capable of being tailored around the car, driver and conditions.

Why choose KW V4 for your BMW F87 M2?

The F87 M2 platform responds particularly well to suspension development, especially when the car is being pushed beyond normal road use.

The KW V4 takes suspension adjustment significantly further than the V3 by providing separate control over rebound, low-speed compression and high-speed compression damping.

This allows the suspension to be tuned around tyre choice, vehicle weight, alignment, road or circuit conditions and driver preference.

Combined with adjustable top mounts, the V4 also provides additional scope for optimising suspension geometry on performance-focused M2 builds.

3-Way Adjustable Damping

One of the defining features of the KW V4 is its advanced 3-way damping adjustment.

Rather than providing a single damping adjustment or independent compression and rebound control, the V4 separates compression damping into low-speed and high-speed adjustment while also providing independent rebound control.

This gives experienced drivers and suspension specialists considerably greater scope for fine-tuning the behaviour of the M2.

Low-Speed Compression Adjustment

Low-speed compression refers to damper movement generated by relatively slower suspension inputs rather than simply the speed of the vehicle.

It has a significant influence on chassis movements such as:

• Body roll during cornering
• Pitch under acceleration
• Dive under braking
• Weight transfer
• General chassis response

Adjusting low-speed compression allows the behaviour of the car during these movements to be fine-tuned without necessarily making the suspension excessively restrictive over sharper surface changes.

High-Speed Compression Adjustment

High-speed compression relates to faster damper movements generated by sharper suspension inputs.

These can include:

• Bumps
• Kerbs
• Surface imperfections
• Sudden road changes
• Aggressive circuit features

Independent high-speed compression adjustment provides additional control over how the suspension absorbs these faster inputs.

This becomes particularly useful when developing a car for circuit use, where the suspension may need to provide strong chassis control while still allowing the wheels to respond effectively to kerbs and surface changes.

Rebound Adjustment

Rebound damping controls how quickly the suspension extends again after being compressed.

Adjusting rebound can influence how settled the vehicle feels following a suspension input and can have a significant effect on overall chassis balance.

Combined with independent high and low-speed compression adjustment, the V4 allows the suspension to be tuned in considerably greater detail than a conventional 1-way or 2-way adjustable coilover.

Adjustable Top Mounts

This version of the KW V4 is supplied with adjustable top mounts.

The performance-focused top mounts provide additional suspension geometry adjustment compared with the standard factory mounting arrangement, with camber adjustment available on the applicable axle.

Additional negative camber can be particularly useful on track-focused M2 builds, helping maintain a more favourable tyre contact patch as the car corners.

This can contribute to:

• Increased front-end grip
• Sharper turn-in
• Improved tyre utilisation
• Greater geometry adjustment
• More flexibility when developing a track setup

A professional geometry setup is strongly recommended after installation.

Adjustable Ride Height

The KW V4 allows the ride height of the BMW F87 M2 and M2 Competition to be adjusted within the approved range for the specific application.

This allows the stance and centre of gravity of the car to be tailored while maintaining the operating range intended for the suspension.

For performance-focused builds, ride height should be selected around suspension travel, tyre clearance and geometry rather than appearance alone.

Excessive lowering can reduce available suspension travel and negatively affect chassis geometry, so lower does not automatically mean faster.

KW INOX-LINE Stainless-Steel Construction

The KW V4 uses KW’s premium INOX-LINE stainless-steel construction.

The corrosion-resistant stainless-steel damper bodies are particularly beneficial for performance cars that continue to see regular road use in UK conditions.

The construction also helps keep the threaded height-adjustment areas serviceable over the long term when the suspension is correctly cleaned and maintained.

BMW F87 M2 & M2 Competition Suspension Upgrade

Both the original F87 M2 and later M2 Competition provide an excellent platform for more advanced suspension development.

The KW V4 can form the centrepiece of a comprehensive chassis setup alongside upgrades such as:

• Performance or semi-slick tyres
• Adjustable suspension arms
• Uprated suspension bushes
• Upgraded anti-roll bars
• Chassis bracing
• Performance braking systems
• Limited-slip differential upgrades
• Lightweight wheels
• Performance wheel alignment

As tyre grip, braking performance and engine output increase, having greater control over suspension behaviour becomes increasingly valuable.

Original M2 & M2 Competition

The original N55-powered M2 and later S55-powered M2 Competition share the F87 platform but have differences in specification, weight distribution and performance.

A more advanced suspension system such as the V4 allows the chassis setup to be developed around the specific vehicle rather than relying solely on a generalised road setup.

This is particularly valuable on modified cars where tyre choice, alignment, weight reduction, power increases and other chassis upgrades can significantly change how the suspension needs to behave.

KW V3 vs KW V4

The KW V3 provides independently adjustable compression and rebound damping and is an excellent choice for road, fast-road and occasional track use.

The KW V4 takes adjustment considerably further.

Its 3-way damping system separates compression into low-speed and high-speed adjustment while retaining independent rebound adjustment.

This provides significantly greater scope for detailed chassis tuning.

For predominantly road-driven M2 builds, the V3 will generally provide more than enough adjustment.

For experienced drivers looking to develop a more specialised fast-road or track setup, the V4 provides a considerably greater tuning window.

KW V4 vs KW Clubsport

The V4 offers an extremely high level of damping adjustability, but choosing between V4 and a Clubsport system should be based on how the car will actually be used rather than simply the number of available adjustments.

KW Clubsport suspension is specifically developed with track-day use and high-grip tyres in mind, while the V4 combines advanced damping technology with the requirements of a high-performance road application.

For serious builds, tyre choice, geometry requirements, road use and frequency of circuit driving should all be considered when selecting between the two.

Fast-Road & Track Use

The KW V4 is particularly well suited to:

• Highly developed fast-road M2 builds
• BMW M2 Competition performance builds
• Cars running high-grip or semi-slick tyres
• Higher-powered vehicles
• Owners wanting advanced damping adjustment
• Cars seeing road and circuit use
• Drivers working with professional suspension setup specialists

The large adjustment range makes correct setup particularly important.

Professional Setup, Alignment & Corner Weighting

Professional installation and setup are strongly recommended for the KW V4.

With adjustable ride height, 3-way damping and adjustable top mounts, there are considerably more variables than with a conventional coilover system.

Once installed, a comprehensive wheel alignment should be carried out so that camber, toe and other geometry settings can be configured around the intended use of the vehicle.

For track-focused builds, corner weighting is also highly recommended.

Damping adjustments should ideally be made methodically and recorded so that changes in vehicle behaviour can be properly evaluated.

Electronic Damper Compatibility

Where the vehicle is equipped with factory electronically controlled dampers, replacing them with conventional adjustable coilovers removes the original electronic damping functionality.

Depending on the exact vehicle and KW application, an appropriate electronic damping cancellation solution may therefore be required.

Please confirm the exact specification of your M2 and selected KW kit before ordering.

Maintenance

Although KW’s INOX-LINE construction provides excellent corrosion resistance, regular suspension maintenance is still recommended.

Threaded adjustment areas, damping adjusters and top mounts should be kept clean and periodically inspected.

This becomes particularly important on vehicles exposed to winter road salt, water, track debris and frequent circuit use.

The adjustable top mounts should also be inspected as part of routine suspension maintenance.
