KW Street Comfort Coilover Kit BMW 5 Series G30

Comfort-focused height-adjustable suspension for BMW 5 Series G30 | Part No. 180200BU

Transform the way your G30 rides with this premium German-engineered comfort coilover package. Designed for UK roads, it delivers a supple, refined feel for daily use while tightening body control when you want to enjoy a spirited drive. Expect smoother motorway miles, calm composure over rough B-roads and a tasteful drop that looks factory-plus rather than slammed.

We run this kit on our own builds and customers love the improvement in ride, grip and confidence. The set offers on-car rebound tuning with 16 precise positions and a user-friendly 10-40 mm ride height window, so you can dial in your preferred balance of comfort and control without compromising usability.

Why this upgrade suits the BMW G30

• Comfort-first damper calibration that removes nervousness and harshness yet sharpens chassis response.
• 16-position rebound control for quick fine-tuning from plush to taut.
• 10-40 mm lowering range for a clean, level stance that works with everyday roads, speed humps and long trips.
• Inox-line stainless construction for outstanding corrosion resistance and long-term serviceability.
• Composite spring perches and dirt-resistant threads to keep adjustments smooth year after year.
• Calmer high-speed stability, reduced pitch and roll, improved steering precision.
• Optimised for use with larger wheel and tyre setups common on the 5 Series.
• Tested adjustment window with road approval documentation for peace of mind.

How it feels on the road

Engineering highlights

• Inox-line stainless steel damper bodies resist rust and keep threads moving freely.
• Trapezoidal thread with composite collars for easy height changes.
• Developed and validated on advanced test rigs and extensive real-world roads.
