KW DDC - ECU coilovers inox - BMW F87 M2 Incl Competition

KW DDC ECU Coilovers – BMW F87 M2 & M2 Competition

The KW DDC ECU Coilovers for the BMW F87 M2 and M2 Competition combine adjustable ride height with electronically controlled adaptive damping, giving drivers the ability to change suspension behaviour at the touch of a button.

Unlike a conventional manually adjustable coilover, the DDC ECU system uses electronically controlled dampers and its own control electronics to provide selectable damping modes. This gives the F87 M2 the ability to switch between a more compliant road setup and firmer performance-focused damping without manually adjusting the dampers.

For M2 and M2 Competition owners looking for a premium suspension upgrade that combines everyday usability, adjustable ride height and electronic damping control, the KW DDC ECU offers a particularly sophisticated solution.

Why choose KW DDC ECU for your BMW F87 M2?

The original F87 M2 platform was not offered with BMW's adaptive suspension system in the same way as some other M models, making the KW DDC ECU particularly interesting.

Rather than simply replacing an existing adaptive system, the DDC ECU allows electronic damping control to be retrofitted to the M2.

This provides much greater flexibility than a conventional fixed-damping coilover while allowing suspension behaviour to be changed without leaving the driver's seat.

For a car used for commuting, longer journeys and spirited driving, this ability to alter the damping characteristics can provide an excellent balance between comfort and performance.

Electronic Adaptive Damping

The defining feature of the KW DDC ECU is its electronically controlled damping.

Rather than manually turning adjusters on each damper, the system electronically alters suspension behaviour using the supplied control system.

This allows the driver to change the character of the suspension depending on how the car is being used.

A more compliant setting can be used for everyday driving and poorer road surfaces, while firmer settings provide increased chassis control for more enthusiastic driving.

The result is a suspension system capable of offering a wider range of behaviour than a traditional fixed-damping coilover.

Selectable Driving Modes

The KW DDC ECU system provides three preset damping modes:

• Comfort
• Sport
• Sport+

Comfort provides the most compliant setting for everyday road use.

Sport increases damping control for faster road driving and more enthusiastic use.

Sport+ provides the firmest and most performance-focused response for maximum chassis control.

The modes can be selected electronically using the KW control system, allowing the suspension character to be changed without manually adjusting individual dampers.

Optional Smartphone Control

The KW DDC ECU system can also be expanded with the optional KW WLAN module.

When fitted, this allows compatible smartphone control through the KW DDC system, providing additional electronic adjustment capability.

This can give owners greater flexibility when configuring the suspension without physically accessing damping adjusters on the vehicle.

The WLAN module is an optional additional component and is not necessarily included with the standard DDC ECU kit.

Adjustable Ride Height

The KW DDC ECU provides adjustable ride height alongside its electronic damping functionality.

For the F87 M2 and M2 Competition application, current specification data lists:

• Front lowering: 15–40mm
• Rear lowering: 20–45mm

The front axle uses threaded strut housings, while the rear retains an adjustable spring perch with separate damper arrangement.

This allows the stance and centre of gravity of the vehicle to be tailored while staying within KW's intended operating range.

Ride height should be chosen around suspension travel, tyre clearance and geometry rather than appearance alone.

KW INOX-LINE Stainless-Steel Construction

The KW DDC ECU uses KW's INOX-LINE stainless-steel construction.

The corrosion-resistant damper bodies are designed for long-term durability and are particularly well suited to cars that continue to see year-round road use.

The stainless-steel construction also helps keep the threaded height-adjustment areas serviceable when regularly cleaned and maintained.

For cars exposed to UK weather, moisture and winter road salt, this is an important advantage.

BMW F87 M2 Retrofit Adaptive Suspension

One of the biggest advantages of the DDC ECU system is that it effectively brings adaptive suspension functionality to the F87 M2 platform.

Rather than choosing one fixed suspension compromise, the electronically controlled dampers allow the chassis behaviour to be altered depending on the situation.

This makes the kit particularly attractive for M2 owners whose cars need to perform multiple roles.

For example, the same vehicle can be configured with a more compliant suspension setting for commuting or motorway journeys before changing to a firmer mode for a fast-road drive.

BMW F87 M2 & M2 Competition Suspension Upgrade

The DDC ECU can form the foundation of a more developed M2 chassis setup alongside upgrades such as:

• Performance tyres
• Uprated suspension bushes
• Adjustable suspension arms
• Chassis bracing
• Upgraded anti-roll bars
• Performance braking systems
• Lightweight wheels
• Performance wheel alignment

As tyre grip and engine performance increase, improved damper control can help the chassis make more effective use of the available performance.

KW DDC ECU vs KW V3

The KW V3 and DDC ECU take very different approaches to suspension adjustment.

The KW V3 provides manually adjustable compression and rebound damping, giving the driver or suspension specialist detailed mechanical control over the setup.

The DDC ECU instead uses electronically controlled damping that can be changed from inside the vehicle.

For drivers who enjoy manually developing and fine-tuning suspension settings, the V3 may be preferable.

For drivers who value being able to change suspension behaviour quickly between different driving situations, the DDC ECU offers much greater convenience.

KW DDC ECU vs KW V4

The KW V4 provides considerably greater manual damping adjustment, including separate low-speed compression, high-speed compression and rebound control.

This makes the V4 better suited to experienced drivers who want detailed chassis tuning around tyres, geometry and track conditions.

The DDC ECU has a different priority.

Rather than providing extensive manual adjustment, it offers electronically selectable damping settings that can be changed quickly during normal use.

For mixed road use, this can make the DDC ECU more convenient and versatile.

KW DDC ECU vs KW Clubsport

KW Clubsport suspension is developed with a much stronger emphasis on circuit performance, aggressive geometry and high-grip tyres.

The DDC ECU is more focused on combining road usability with adaptable performance.

For regular track use, a Clubsport system may offer a more appropriate foundation.

For an M2 that spends most of its time on the road but is still driven enthusiastically, the DDC ECU provides the ability to switch between different suspension characteristics without compromising day-to-day usability.

Original M2 & M2 Competition Compatibility

This DDC ECU application is listed for both versions of the F87 platform:

• BMW F87 M2
• BMW F87 M2 Competition

Current fitment information lists KW part number:

Road & Fast-Road Use

The KW DDC ECU is particularly well suited to:

• Daily-driven BMW F87 M2 models
• BMW M2 Competition road builds
• Fast-road cars
• Owners wanting adaptive damping
• Cars used for both commuting and spirited driving
• Drivers wanting electronic suspension adjustment
• Owners who prefer in-car adjustment over manual damper controls

Its ability to offer different damping characteristics makes it particularly useful for cars that need to perform well across a wide variety of road conditions.

Professional Installation & Alignment

Professional installation is strongly recommended for the KW DDC ECU.

Unlike a conventional purely mechanical coilover system, installation involves both the suspension components and the electronic control system.

The wiring, ECU and control components should therefore be installed correctly alongside the dampers.

Once fitted, a full four-wheel alignment should be carried out to ensure toe, camber and other geometry settings are appropriate for the selected ride height.

Maintenance

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

Threaded adjustment areas and spring platforms should be kept clean, particularly on cars exposed to winter road salt and contamination.

The electronic wiring and connections should also be inspected as part of normal vehicle maintenance to ensure they remain secure and protected.
