KW Coilover suspension V2 comfort - BMW 1 Series F20 M140i

KW V2 Comfort Coilovers – BMW 1 Series F20 M140i

The KW V2 Comfort Coilovers for the BMW 1 Series F20 M140i are designed for drivers who want improved handling and adjustable ride height without sacrificing everyday comfort.

Developed specifically for road use, the V2 Comfort combines KW’s height-adjustable stainless-steel coilover construction with 16-click adjustable rebound damping and a comfort-oriented damper setup. The result is a suspension system that can make the M140i feel more composed and controlled while remaining well suited to daily driving, longer journeys and fast-road use.

Why choose KW V2 Comfort for your BMW M140i?

The F20 M140i combines strong performance with everyday usability, and the KW V2 Comfort is aimed at owners who want to improve the chassis without making the car unnecessarily harsh.

Compared with more aggressively focused coilovers, the V2 Comfort places greater emphasis on ride quality while still providing useful control over body movement and steering response.

This makes it particularly suitable for road-driven M140i builds where comfort, refinement and handling all matter.

16-Click Rebound Damping Adjustment

The KW V2 Comfort allows the rebound damping to be adjusted through 16 clicks.

Rebound damping influences how quickly the suspension extends after being compressed and has a direct effect on body control, stability and ride behaviour.

Increasing rebound damping can provide a more controlled and responsive feel, while reducing it can allow the suspension to operate more comfortably over uneven roads.

This gives M140i owners useful flexibility to tailor the suspension around their own driving style and comfort preference without altering the factory-optimised compression damping.

Comfort-Focused Suspension Setup

The defining feature of the V2 Comfort is its emphasis on ride quality.

KW develops the suspension specifically to combine lowering and improved driving dynamics with a more comfort-oriented damper setup than its more aggressively focused coilover systems.

For an F20 M140i used regularly on UK roads, this makes the V2 Comfort particularly appealing where improved chassis control is wanted without turning the car into an uncompromising track-focused setup.

Adjustable Ride Height

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

For this application, published fitment data lists approximately:

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

This allows the stance of the M140i to be tailored while maintaining the operating range intended for the suspension system.

Ride height should always be set with suspension travel, tyre clearance and wheel alignment in mind.

KW INOX-LINE Stainless-Steel Construction

KW uses high-quality stainless-steel strut housings within the V2 Comfort range.

The corrosion-resistant construction is particularly useful for year-round road cars exposed to rain, dirt and winter road salt.

It also helps ensure the height-adjustment mechanism remains serviceable over the long term when the suspension is correctly maintained.

BMW F20 M140i Suspension Upgrade

The F20 M140i has substantial straight-line performance, but suspension upgrades can help make better use of that performance through improved chassis control.

The KW V2 Comfort can work particularly well alongside:

• Performance tyres
• Uprated suspension bushes
• Rear subframe upgrades
• Adjustable suspension arms
• Chassis bracing
• Performance alignment settings

For road and fast-road builds, the combination of coilovers and a quality four-wheel alignment can significantly improve how composed and predictable the car feels.

V2 Comfort vs Standard KW V2

Both systems offer adjustable rebound damping and height-adjustable coilover suspension.

The main difference is the intended character.

The standard KW V2 is more traditionally performance focused, while the V2 Comfort uses a comfort-oriented spring and damper setup aimed at frequent road use and everyday driving.

For an M140i owner who wants a premium suspension upgrade while retaining a more forgiving ride, the V2 Comfort is likely to be the better option.

Ideal for Daily-Driven M140i Builds

The KW V2 Comfort is particularly well suited to:

• Daily-driven BMW M140i models
• Fast-road cars
• Long-distance driving
• Owners wanting reduced body movement without excessive stiffness
• Cars running larger wheels or lower-profile tyres
• Drivers wanting ride-height and rebound adjustment without moving to a track-focused setup

For dedicated track cars, a more performance-oriented KW V3, V4 or Clubsport system may be more appropriate.

Electronic Damper Compatibility

Some BMW F20 M140i models may be equipped with electronically controlled dampers.

Where the factory electronic damping system is present, it may need to be deactivated when fitting conventional coilovers. Some application-specific KW kits include the necessary cancellation solution, but this should always be confirmed against the exact part number and vehicle specification before ordering.

If you're unsure whether your M140i has adaptive suspension, contact us before ordering and we can help identify the correct kit.

Professional Installation & Alignment

Professional installation is recommended for any coilover suspension system.

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

For fast-road use, a performance-oriented alignment can further improve steering response and overall chassis balance.

Maintenance

The stainless-steel construction of the KW V2 Comfort provides strong corrosion resistance, but regular maintenance is still worthwhile.

The threaded height-adjustment areas should be kept clean, particularly on cars used throughout winter, and the suspension should be inspected periodically for contamination, damaged components or loose hardware.
