Comfort-focused height adjustable suspension for BMW F31 and F36 AWD

Looking for a smoother, more grown-up ride without losing the precision your BMW is known for? This KW Street Comfort setup is a premium road-biased suspension upgrade for the BMW 3 Series F31 Touring and 4 Series F36 Gran Coupé all-wheel drive models. It blends plush ride quality with confident control, adds proper ride height tuning, and includes the electronic damper cancellation so no warning lights on the dash.

Part number: 180200AD

Why this is the right suspension upgrade

Daily driver friendly yet superb on fast B roads, these stainless steel-bodied dampers and matched springs deliver a composed, quiet and refined ride on UK roads. Our team has fitted this kit on multiple F31 and F36 cars and customer feedback has been consistently excellent. Less crashiness over potholes, better body control in corners, and a tidy stance that still clears speed bumps.

Highlights

  • Ride height tuning within an approx 10 to 40 mm lowering range for a subtle, tasteful drop
  • Rebound adjustment with 16 clicks to tailor comfort and support to your preference
  • Inox-line stainless struts for outstanding corrosion resistance in UK weather
  • Durable composite spring seats and dirt-resistant threads for easy long-term adjustment
  • Includes electronic damper cancellation hardware for vehicles with factory adaptive dampers
  • Part approval per §19.3 as listed by KW

Real world improvement

Set it soft for motorway mileage and commuting, or add firmness for sharper response with larger wheels and tyres. Expect calmer vertical movement, reduced float, less nose dive under braking and a planted feel that flatters the chassis on uneven tarmac.
