KW Coilover suspension V3 inox - BMW 1 Series E81 / E82 / E87

KW Variant 3 Coilovers – BMW 1 Series E81 / E82 / E87

Upgrade the suspension of your BMW 1 Series with KW Variant 3 Coilovers, combining adjustable ride height with independently adjustable rebound and compression damping for significantly greater control over chassis behaviour.

The KW V3 is aimed at drivers who want a more advanced suspension setup than the V1 or V2, allowing both major damping characteristics to be tuned independently around road conditions, tyre choice and intended use.

KW part number:

35220039

Independently Adjustable Rebound & Compression Damping

The key feature of the KW Variant 3 is independent rebound and compression damping adjustment.

This allows you to fine-tune different aspects of the suspension response rather than relying on a single combined adjustment.

Rebound adjustment can influence:

• Body control
• Steering response
• Weight transfer
• Ride characteristics
• Chassis balance

Compression adjustment can influence:

• Support during cornering
• Brake dive
• Squat under acceleration
• Suspension response under load
• Overall chassis stability

KW uses its TVR-A rebound and TVC-A compression damping technology in the V3 range.

Adjustable Ride Height

Ride height is adjustable at both axles.

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 exact approved adjustment 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 3 uses KW’s corrosion-resistant INOX-LINE stainless-steel construction.

Key features include:

• Stainless-steel damper bodies
• Height-adjustable suspension
• Independent rebound adjustment
• Independent compression adjustment
• Vehicle-specific spring and damper calibration
• TÜV-approved adjustment range

The stainless-steel construction is designed to improve long-term corrosion resistance and help preserve the threaded ride-height adjustment system during road use.

Designed for Fast Road & Track Use

The KW V3 is particularly well suited to:

• Fast-road driving
• Track days
• Clubsport builds
• Performance-focused daily cars
• Higher-grip tyre setups
• Drivers wanting detailed damping adjustment

Compared with the V1 or V2, the V3 gives the driver considerably more flexibility to tailor suspension behaviour around the car and intended use.

Compatibility – Please Check Carefully

KW part number 35220039 is listed for:

• BMW 1 Series E81
• BMW 1 Series E82 Coupe
• BMW 1 Series E87

KW’s own part-number documentation lists the kit for E81/E82/E87 1 Series applications across all engines, while application data shows a wide selection of petrol and diesel variants.

Published applications include models such as:

• 116i
• 118i
• 120i
• 125i
• 128i
• 130i
• 135i
• 116d
• 118d
• 120d
• 123d

Exact compatibility still depends on chassis, production date, axle loads and drivetrain.

E81 / E87 Fitment Limits

For BMW E81 and E87 applications:

• Maximum front axle load: 920kg
• Maximum rear axle load: 1060kg
• Front lowering: 35–65mm
• Rear lowering: 35–65mm

These figures apply to the relevant rear-wheel-drive hatch applications listed for this kit.

E82 Coupe Fitment Limits

For BMW E82 Coupe applications:

• Maximum front axle load: 945kg
• Maximum rear axle load: 1070kg
• Front lowering: 30–55mm
• Rear lowering: 25–50mm

The E82 therefore uses different approved lowering and axle-load limits despite sharing the same KW part number.

Important Fitment Notes

This application is intended for rear-wheel-drive vehicles.

KW also notes that additional wheel spacers may be required with some standard 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
• Drivetrain
• Wheel and tyre specification

If you're unsure whether KW 35220039 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 vs V3

KW V1:

• Adjustable ride height
• Factory-set damping

KW V2:

• Adjustable ride height
• Adjustable rebound damping

KW V3:

• Adjustable ride height
• Independently adjustable rebound damping
• Independently adjustable compression damping

The V3 is therefore the most adjustable of these three road-focused KW variants and is particularly suitable for drivers who want greater control over suspension setup.

Product Image & Configuration Note

Product images are generic and are intended for illustration purposes only.

The exact components supplied can vary depending on vehicle application, including:

• Spring configuration
• Damper layout
• Rear height-adjustment components
• Adjustment hardware
• Mounting components

If you have specific requirements or want confirmation of the exact kit configuration, please contact The Rosso Corsa Collective before ordering.

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.

Because the V3 provides independent damping adjustment, setup changes should be made systematically and recorded so the vehicle can be returned to a known baseline.
