KW Coilover suspension V1 inox (incl. deactivation for electronic dampers) - BMW 1/2 Series F2X

KW V1 Coilovers with Electronic Damper Deactivation – BMW 1 Series F20 M140i

The KW V1 Coilovers for the BMW F20 M140i are designed for drivers looking for a premium height-adjustable suspension upgrade with a fixed, vehicle-specific damping setup.

This version is intended for vehicles equipped with factory electronic dampers and includes the required deactivation solution, allowing the original electronically controlled suspension to be replaced without leaving the factory damping system active.

With KW’s stainless-steel INOX-LINE construction, adjustable ride height and pre-configured damping, the V1 is a strong choice for road and fast-road M140i builds where simplicity, durability and everyday usability are priorities.

Why choose KW V1 for your BMW M140i?

The F20 M140i combines strong performance with everyday practicality, and the KW V1 provides a straightforward way to improve stance and chassis control without introducing manual damping adjustment.

The suspension is developed with a fixed spring and damper setup for the specific vehicle application, meaning the damping is already configured by KW.

For owners who want to fit the suspension, set the ride height and enjoy the car without having to experiment with damper settings, the V1 is one of the simplest options in the KW range.

Electronic Damper Deactivation Included

This version of the KW V1 is intended for BMW F20 M140i models equipped with factory electronic damping.

When conventional coilovers are fitted, the original electronically controlled dampers are removed and the factory adaptive damping function can no longer operate.

The included deactivation solution is designed to prevent the vehicle from continuing to expect signals from the original dampers, helping avoid suspension-related warning messages after installation.

The original electronic damping functionality will no longer be available once the KW V1 system is installed.

Fixed Vehicle-Specific Damping

The KW V1 uses a fixed damping configuration developed specifically for the vehicle application.

Unlike the KW V2 or V3, there are no manual damping adjusters to configure.

This makes the V1 particularly suitable for owners who want a well-developed suspension setup without the added complexity of rebound or compression adjustment.

KW determines the damper characteristics during development, allowing the suspension to provide a balance between improved chassis control and everyday road usability.

Adjustable Ride Height

The KW V1 allows the ride height of the BMW F20 M140i to be adjusted within the approved application-specific range.

This allows owners to:

• Reduce arch gap
• Achieve a lower, more purposeful stance
• Fine-tune front-to-rear ride height
• Adjust the setup around wheel and tyre fitment
• Lower the vehicle without being restricted to the fixed drop of conventional lowering springs

Ride height should still be selected with tyre clearance, suspension travel and geometry in mind.

A professional four-wheel alignment is recommended after installation.

KW INOX-LINE Stainless-Steel Construction

The KW V1 uses KW’s INOX-LINE stainless-steel strut construction.

This provides strong resistance to corrosion and is particularly useful for cars driven throughout the year in UK conditions.

The stainless construction also helps keep the threaded height-adjustment areas serviceable over the long term when correctly maintained.

For an M140i that sees regular road use, rain and winter conditions, this is one of the key advantages of the KW system.

BMW F20 M140i Suspension Upgrade

The M140i responds well to suspension improvements, particularly where greater grip or increased engine performance places more demand on the chassis.

The KW V1 can work alongside upgrades such as:

• Performance tyres
• Uprated suspension bushes
• Adjustable suspension arms
• Rear subframe upgrades
• Chassis bracing
• Limited-slip differential
• Performance alignment settings

For a road and fast-road build, a quality coilover setup combined with a proper geometry adjustment can significantly improve the overall balance and confidence of the car.

KW V1 vs KW V2

The KW V1 and V2 both provide adjustable ride height and use KW’s premium INOX-LINE stainless-steel construction.

The main difference is damping adjustment.

The V1 uses fixed vehicle-specific damping, while the V2 adds manually adjustable rebound damping.

For owners who want a straightforward suspension upgrade without needing to tune damper settings, the V1 is the simpler choice.

For drivers who want greater control over ride and chassis response, the V2 provides additional adjustability.

KW V1 vs ST X

Both the KW V1 and ST X provide adjustable ride height with fixed damping.

The KW V1 sits higher in the product range and uses KW’s stainless-steel INOX-LINE construction, while the ST X uses galvanised steel damper bodies.

For owners prioritising premium materials, long-term corrosion resistance and the KW product range, the V1 is the more premium option.

Road & Fast-Road Use

The KW V1 is particularly well suited to:

• Daily-driven BMW M140i models
• Fast-road builds
• Owners wanting adjustable ride height
• Cars with factory adaptive dampers
• Drivers who do not require manual damping adjustment
• Owners wanting a premium replacement for the original suspension

For more demanding track use or drivers wanting greater setup control, the KW V2, V3 or Clubsport ranges may be more appropriate.

Professional Installation & Alignment

Professional installation is recommended for the KW V1, particularly where the original electronically controlled suspension is being removed.

The damper deactivation components should be installed correctly alongside the new coilover system.

Once fitted, the vehicle should receive a full four-wheel alignment so that toe, camber and other geometry settings can be checked following the change in ride height.

Maintenance

Although the INOX-LINE stainless-steel construction provides excellent corrosion resistance, the suspension should still be maintained regularly.

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

Regular inspection will help ensure the suspension remains adjustable and performs consistently over time.
