What you get

• Ride height adjustment approximately 10 to 40 mm for a subtle, practical drop with an even wheel gap
• 16-step rebound tuning so you can easily set it softer for comfort or firmer for control
• Inox-Line stainless bodies for superb corrosion resistance, perfect for year-round British weather
• Vehicle-specific spring and damper rates developed on KW’s test rigs and validated on the road
• Composite spring seats with trapezoid threads that stay free-moving for easy adjustments over time
• Part approval §19.3 as per official documentation
• Limited Lifetime Warranty on damper units from the manufacturer

Real-world comfort, genuine control

The rebound adjustment is the magic here. Dial it back a few clicks for a plusher ride on rough urban streets and winter-worn B-roads. Add a few clicks when you want extra composure for spirited drives or when running larger wheels and tyres. Changes are immediate and easy to feel, so you can tailor the car to your route and load.

Lower and level your BMW

Achieve an elegant, factory-like drop without ruining usability. The 10 to 40 mm range lets you remove the arch gap, improve the centre of gravity and tidy the stance while keeping comfort. Perfect for a clean, daily-friendly look.

Built to last

Inox stainless construction resists rust, road salt and grime, and the robust threads make ride height changes straightforward even after years of use. This is a long-term upgrade that keeps performing through every season in the UK.
