Why choose KW Street Comfort for your M135i or M140i
- Comfort-oriented damping that makes daily driving genuinely smoother while retaining sharp, confident handling
- 16-click adjustable rebound so you can fine-tune ride comfort and body control to suit roads, wheels and driving style

Real-world comfort, real performance
If your factory suspension feels too crashy or your current aftermarket setup is too harsh, KW Street Comfort is the upgrade that brings back ride quality. The carefully matched springs and comfort-biased damping reduce harsh impacts and road noise while improving stability, steering precision and traction. Dial in more rebound for extra composure and reduced body movement, or back it off for maximum plushness. It is the ideal daily-driven coilover for the BMW 1 Series hot hatch platform.
Built to be used every day
KW’s inox-line stainless steel bodies and high-quality components resist corrosion and keep adjustments free over time. The result is a coilover kit that stays quiet, consistent and easy to set up, season after season.
