KW Variant 1 Coilovers – BMW 1 Series E81 / E82 / E87
Upgrade the suspension of your BMW 1 Series with KW Variant 1 Coilovers, combining individually adjustable ride height with factory-calibrated damping and KW’s corrosion-resistant INOX-LINE stainless-steel construction.
The KW V1 is designed for drivers who want a premium height-adjustable suspension system without needing to manually tune the dampers.
KW part number:
10220039
Factory-Set Damping
The KW Variant 1 uses a fixed damping setup developed and pre-configured by KW for the intended vehicle application.
This makes the V1 particularly suitable for drivers who want:
- Adjustable ride height
- Improved chassis control
- A sportier road setup
- A pre-engineered spring and damper combination
- No requirement to manually adjust damping
KW describes the V1 as using a sporty yet harmonious factory damping setup designed to balance handling, comfort and everyday usability.
Adjustable Ride Height
Ride height can be adjusted within the vehicle-specific TÜV-tested range.
For BMW E81 / E87 applications:
- Front lowering: approximately 35–65mm
- Rear lowering: approximately 35–65mm
For BMW E82 Coupe applications:
- Front lowering: approximately 30–55mm
- Rear lowering: approximately 25–50mm
The E81/E87 use a threaded front strut with a separately height-adjustable rear spring arrangement.
This gives you greater control over:
- Vehicle stance
- Wheel and tyre fitment
- Arch clearance
- Centre of gravity
- Overall chassis setup
The suspension should always be adjusted within the approved range and with sufficient clearance and suspension travel.
KW INOX-LINE Stainless Steel
One of the main advantages of the KW Variant 1 is its INOX-LINE stainless-steel construction.
The stainless-steel strut housings are designed to provide long-term corrosion resistance while helping keep the ride-height adjustment mechanism usable over time.
Key features include:
- Stainless-steel INOX-LINE struts
- Corrosion-resistant construction
- Dirt-resistant threaded adjustment
- Height-adjustable spring platforms
- Vehicle-specific spring and damper calibration
Regular cleaning and maintenance is still recommended, particularly on cars used throughout winter.
Designed for Fast-Road Performance
The KW V1 is particularly well suited to:
- Daily-driven performance cars
- Fast-road builds
- Lowered road cars
- Drivers wanting premium suspension without damping adjustment
- Cars requiring a more controlled and purposeful stance
A properly installed V1 setup can help improve:
- Body control
- Steering response
- Cornering stability
- Chassis confidence
- Overall suspension response

Important Fitment Restrictions
This application is for rear-wheel-drive vehicles and should not be assumed suitable for xDrive models.
KW also notes that wheel spacers may be required with certain original wheel and tyre combinations to achieve sufficient clearance between the wheel and suspension components.
Before ordering, please confirm:
- Exact chassis
- Engine variant
- Production year
- Front axle load
- Rear axle load
- Rear-wheel-drive configuration
- Wheel and tyre specification
If you're unsure whether KW 10220039 is correct for your BMW, contact The Rosso Corsa Collective with your registration or vehicle details and we can help confirm fitment.
KW V1 vs V2 & V3
KW V1:
- Adjustable ride height
- Factory-set damping
- INOX-LINE stainless-steel construction
KW V2:
- Adjustable ride height
- Adjustable rebound damping
KW V3:
- Adjustable ride height
- Independently adjustable rebound and compression damping
The V1 is therefore ideal for drivers who want KW build quality and ride-height adjustment without the additional setup involved with adjustable damping.
