KW Variant 2 Coilovers – BMW 1 Series E81 / E82 / E87
Upgrade the suspension of your BMW 1 Series with KW Variant 2 Coilovers, combining adjustable ride height with adjustable rebound damping for greater control over both stance and chassis behaviour.
The KW V2 builds on the V1 by adding user-adjustable rebound damping while retaining KW’s corrosion-resistant INOX-LINE stainless-steel construction.
KW part number:
15220039
Adjustable Rebound Damping
The main advantage of the KW V2 over the V1 is adjustable rebound damping.
Rebound adjustment allows you to fine-tune how quickly the suspension extends after compression, giving you greater control over:
- Body roll
- Pitch under braking
- Chassis response
- Steering feel
- Ride comfort
- Fast-road setup
- Trackday setup
KW V2 systems use externally adjustable rebound damping, allowing the suspension character to be tailored more closely to the driver and vehicle setup.
Adjustable Ride Height
The V2 also provides individually adjustable ride height, allowing the car to be set up around:
- Preferred stance
- Wheel and tyre fitment
- Arch clearance
- Centre of gravity
- Intended road or track use
The exact approved lowering range depends on chassis and vehicle specification, so the supplied KW documentation should always be followed during installation.
KW INOX-LINE Stainless Steel
The KW Variant 2 uses KW’s INOX-LINE stainless-steel construction.
Key features include:
- Stainless-steel strut housings
- Corrosion-resistant construction
- Height-adjustable spring platforms
- Adjustable rebound damping
- Composite spring perches
- Vehicle-specific spring and damper calibration
The stainless-steel design helps protect the threaded ride-height adjustment system during long-term road use.
Designed for Fast-Road Performance
The KW V2 is particularly well suited to:
- Daily-driven performance cars
- Fast-road builds
- Lowered road cars
- Drivers wanting adjustable damping
- Occasional track use
- Cars running upgraded wheels and tyres
Compared with the V1, the V2 gives the driver more control over suspension behaviour without moving to the more complex independent compression and rebound adjustment of the V3.
Compatibility – Please Check Carefully
KW part number 15220039 is listed for:
- BMW 1 Series E81
- BMW 1 Series E82
- BMW 1 Series E87
KW identifies this part number specifically as a V2 Coilover Kit for BMW 1 Series E81/E82/E87 applications.
Exact compatibility should still be confirmed using:
- Exact chassis

- Rear axle load
- Drivetrain
- Factory suspension specification
If you're unsure whether KW 15220039 is correct for your BMW, contact The Rosso Corsa Collective with your vehicle details before ordering.
Important Fitment Note
This product should not be selected purely from the broad E81, E82 or E87 chassis code.
Different engine and body configurations can have different axle loads and approved lowering ranges, so vehicle-specific application data should always be checked before purchase.
KW V1 vs V2
KW V1:
- Adjustable ride height
- Factory-set damping
- INOX-LINE stainless-steel construction
KW V2:
- Adjustable ride height
- Adjustable rebound damping
- INOX-LINE stainless-steel construction
The V2 is therefore the better option for drivers who want to fine-tune the suspension response rather than relying on a fixed damping setup.
KW V2 vs V3
KW V2:
- Adjustable ride height
- Adjustable rebound damping
- Fixed compression damping
KW V3:
- Adjustable ride height
- Independently adjustable rebound damping
- Independently adjustable compression damping
The V2 provides a useful middle ground between the simplicity of the V1 and the greater tuning range of the V3.

Professional Installation Recommended
Professional installation is recommended.
Following installation, the vehicle should receive a full wheel alignment and geometry setup to ensure correct handling, tyre wear and suspension performance.
Wheel and tyre clearance should also be checked throughout the full steering and suspension range.
