Comfort adjustable suspension for BMW F31 Touring, F34 Gran Turismo and F36 Gran Coupé

Elevate everyday driving without ruining ride quality. This KW Street Comfort height adjustable suspension kit brings genuine comfort, composure and control to the F3x platform while giving you a tasteful drop. Enjoy precise rebound tuning in 16 steps, a 10 to 40 mm ride height range and corrosion resistant Inox-Line stainless construction that stands up to British weather. Ideal for daily use, motorway miles and B-road fun with an OEM+ feel.

Why enthusiasts choose this kit

  • Ride height adjustment approximately 10 to 40 mm for the perfect stance and practicality
  • 16-stage rebound adjustment to fine tune body control and comfort
  • Inox-Line stainless steel struts and corrosion resistant hardware for long service life
  • Smooth trapezoid thread and composite spring seats for easy height changes year after year
  • Comfort oriented spring and damper rates developed for real roads

Real-world benefits

If lowering springs or harsh sport dampers have made your BMW too crashy, this kit restores compliance while tightening up roll and pitch. Add clicks for a tauter feel with bigger wheels and tyres or back it off for long trips. Expect calmer high speed stability, better mid-corner support and a premium ride that still feels sporty.
