Part number: KW 1802000S

Why customers love this upgrade

• Comfort biased damping for real world roads, speed humps and B road surfaces
• Rebound adjustability with 16 steps for fine tuning body control and ride comfort
• Ride height adjustment typically within 10 to 40 mm for a tasteful drop and better stance
• Inox-Line stainless construction for outstanding corrosion resistance in the UK climate
• Easy to adjust trapezoid threads and composite spring seats that keep working season after season
• Improved stability and reduced float without ruining daily drivability

Smoother, quieter, more composed

Set it softer for pothole ridden streets, then add a few clicks for a tauter feel on fast A roads. The matched spring rates and shortened damper housings let you lower the car while keeping a compliant ride. It is the ideal comfort focused suspension for owners who want a refined ride, better stance and confidence in poor weather without the harshness of track oriented kits.
