KW V3 / Variant 3 Coilovers for BMW Z4 E89 sDrive 18i 20i 23i 28i - Height Adjustable Suspension Kit, 2-Way Rebound & Compression Damping, Inox-Line Stainless, Fast Road/Track - Coilover Lowering Kit - 35220072 / 35220087

BMW Z4 E89 Performance Suspension Upgrade - Two-way Adjustable Coilover System

Unlock sharper response, extra mechanical grip and a road-friendly ride with this premium two-way adjustable coilover suspension for the BMW Z4 E89. Perfect for fast road use, weekend blasts and track days, this stainless-bodied kit delivers precise control over ride height, rebound and bump so you can dial in the balance your Z4 deserves.

We run this kit on our own builds and customer cars and the feedback is consistent: tighter body control, crisper turn-in, improved traction on UK B-roads and a composed, comfortable ride on the daily. It is a proper step up from factory dampers and springs if you want real-world pace without sacrificing refinement.

Key benefits

• Independent damping control - 16-stage rebound and 12-stage bump for fine-tuning balance and compliance
• Ride height adjustment - set your preferred stance and centre of gravity for performance and aesthetics
• Stainless steel shock bodies - corrosion resistant housings for long-term reliability in UK weather
• Sharper handling - reduce roll, improve front-end bite and maximise traction out of corners
• Road and circuit ready - engineered for fast road comfort with serious pace on track
• Developed on a 7-post rig and validated on demanding test routes including the Nordschleife

Technical highlights

• Separate rebound and bump adjustment - alter damper behaviour without changing springs
• Low-speed compression adjuster at the damper base - quick, easy clicks for on-the-fly tuning
• Twin-tube architecture with clearly indexed adjusters for repeatable settings
• Ride-height control via dirt-resistant trapezoid thread and composite spring perches
• Comprehensive documentation and parts approval available
