Real-world comfort, real control
If your stock suspension feels too harsh or your current aftermarket kit is wearing you out, KW Street Comfort is the answer. Shorter damper housings and comfort-oriented spring and damper rates give you a compliant ride for long trips, while the 16-step rebound adjustment lets you set it softer for comfort or firmer for extra body control and stability.
Upgrading to bigger wheels and tyres on your BMW 6 Series E63 or E64 Cabrio or Coupe? Dial in the rebound so the car stays composed while maintaining the comfort you want from a premium grand tourer.
Built to last
KW’s stainless steel inox-line bodies and high-quality components resist corrosion year after year. The dirt-resistant trapezoid thread and composite spring perch make height adjustments straightforward even after many winters.
