KW Comfort Adjustable Suspension for BMW 5 Series E61 Touring 2004 to 2010 - Part No. 18020045

Give your BMW E61 estate the ride quality it deserves. This premium KW comfort-oriented adjustable suspension kit brings a calmer, more composed drive on UK roads while keeping your 5 Series sharp and confidence-inspiring. Set your stance within a tasteful 10 to 40 mm range and fine tune feel with 16 clicks of rebound control for everything from long motorway runs to B-road commutes.

Perfect if your factory setup feels crashy or tired, this German-engineered package delivers a supple, mature ride without the float. Stainless steel damper bodies resist corrosion year round, the adjustment hardware stays movable thanks to a grit-resistant thread design and composite spring seats, and the vehicle-specific spring and damper pairing has been developed with comfort and stability in mind.

Why enthusiasts choose this kit

• Refined ride for daily use with sure-footed handling when you want to press on.
• Ride height adjustment approx. 10 to 40 mm for a smart, practical drop on an E61 Touring.
• 16-stage rebound adjustability to dial in plushness or body control in seconds.
• Inox stainless construction for outstanding durability in wet, salty UK conditions.
• Thread design resists dirt ingress and the composite perch helps smooth height changes over time.
• Vehicle-specific comfort tuning for British tarmac and real-world loads.
• Approval documentation available via the links below.

We have fitted this setup ourselves on customer cars and feedback has been consistently positive. Owners report less harshness over potholes, better high speed stability and a subtle drop that still clears speed bumps and keeps family and luggage duties easy.
