KW Coilover suspension V2 inox - BMW 1 Series F20 M140i

KW V2 Coilovers – BMW 1 Series F20 M140i

The KW V2 Coilovers for the BMW F20 M140i are a premium road and fast-road suspension upgrade designed for drivers who want adjustable ride height with the added benefit of manually adjustable rebound damping.

Sitting above the KW V1, the V2 retains KW’s stainless-steel INOX-LINE construction and vehicle-specific spring and damper tuning while adding extra control over suspension response. This makes it a strong option for M140i owners who want to fine-tune ride quality and chassis behaviour without moving to a more advanced 2-way adjustable system.

Why choose KW V2 for your BMW M140i?

The F20 M140i combines strong performance with everyday usability, and the KW V2 is well suited to owners who want to improve the chassis while retaining a road-friendly setup.

The adjustable rebound damping gives greater control over how quickly the suspension extends after compression, allowing the car to be tuned towards either a more compliant road setup or a firmer, more controlled fast-road feel.

For drivers who want more adjustability than the KW V1 without the complexity of independently adjustable compression and rebound damping, the V2 sits in an excellent middle ground.

Key Features

• KW V2 coilover suspension
• BMW F20 M140i application
• Adjustable ride height
• Adjustable rebound damping
• Vehicle-specific spring and damper tuning
• KW INOX-LINE stainless-steel construction
• Improved body control
• Road and fast-road focused setup
• Corrosion-resistant construction
• Premium KW suspension system
• Greater setup flexibility than the KW V1

Adjustable Rebound Damping

The defining feature of the KW V2 is its manually adjustable rebound damping.

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

Increasing rebound damping can provide stronger body control and a more settled feel during braking, cornering and directional changes.

Reducing rebound can allow the suspension to move more freely and provide greater compliance over rougher roads.

This gives M140i owners useful flexibility to tailor the suspension around driving style, tyre choice and road conditions.

Adjustable Ride Height

The KW V2 allows the ride height of the BMW F20 M140i to be adjusted within the approved application-specific range.

This makes it possible 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 suspension travel, tyre clearance and geometry in mind.

A professional four-wheel alignment is recommended after installation.

KW INOX-LINE Stainless-Steel Construction

The KW V2 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 major advantages of the KW system.

BMW F20 M140i Suspension Upgrade

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

The KW V2 can work well alongside upgrades such as:

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

For road and fast-road builds, the combination of adjustable rebound damping and a quality geometry setup can significantly improve steering response, body control and overall chassis balance.

KW V1 vs KW V2

The KW V1 and V2 both provide adjustable ride height and use KW’s stainless-steel INOX-LINE 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 is the more flexible option.

KW V2 vs KW V3

The KW V2 provides adjustable rebound damping with compression damping fixed by KW.

The KW V3 adds independent compression and rebound adjustment, providing much greater setup flexibility.

For predominantly road and fast-road use, the V2 offers a strong balance between adjustability and simplicity.

For drivers who want more detailed chassis tuning or more regular track use, the V3 is the more advanced option.

Road & Fast-Road Use

The KW V2 is particularly well suited to:

• Daily-driven BMW M140i models
• Fast-road builds
• Owners wanting adjustable ride height
• Drivers who want manual damping adjustment
• Cars running performance tyres
• Owners looking for a premium road-focused suspension system

For more demanding track use, a KW V3 or Clubsport system may be more appropriate.

Electronic Damper Compatibility

Some BMW F20 M140i models are equipped with factory adaptive electronic dampers.

Where conventional KW coilovers replace the original electronically controlled dampers, the factory adaptive damping function will no longer operate.

Depending on the exact vehicle and kit specification, an electronic damping cancellation solution may be required to prevent warning messages.

Please confirm the exact application before ordering if your M140i is equipped with adaptive suspension.

Professional Installation & Alignment

Professional installation is recommended for the KW V2.

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.

For fast-road builds, a more performance-oriented geometry setup can further improve steering response and tyre utilisation.

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.
