• Fixed-rate damping pre-calibrated by KW for the E63 and E64 platform
• Inox steel damper bodies for outstanding longevity in UK weather
• Ride height adjustability for precise arch-to-tyre fitment and stance
• Trapezoidal threads and composite spring perches for easy adjustments over time
• Vehicle-specific development for the 6 Series chassis for balanced handling

Compatibility

Fits BMW 6 Series E63 Coupe and E64 Convertible from 2004 onwards. Ideal if you are searching for a BMW 6er E63 E64 suspension upgrade, adjustable coil over suspension for 6 Series, or a performance spring and damper package for road use.

Lowering range and axle loads

• Front lowering range: 10 to 40 mm
• Rear lowering range: 20 to 50 mm
• Maximum approved axle load: front up to 1100 kg, rear up to 1270 kg

Front height is adjusted using the one-piece composite height adjuster on the strut. Rear height is set with the supplied rear adjuster. On models with separate rear spring and damper, the adjuster is positioned above or below the spring as required. The result is a precise drop, reduced roll and improved steering response without giving up road comfort.

What’s included

• KW Variant 1 Inox-Line coilover kit for front and rear
• Chassis-specific springs, dampers and height-adjust hardware
• Comprehensive fitting and setup documentation

Built to last

Manufactured in Germany with high-quality components, the Variant 1 is engineered for durability and consistent performance. Inox damper bodies resist corrosion, composite spring seats prevent seizure and the dirt-resistant thread design keeps adjustments smooth season after season.

Warranty

• 2-year manufacturer warranty as standard
• Warranty can extend up to 5 years when installed by an approved specialist
