MSS Urban is a spring-based suspension kit built for SUV owners whose main complaint is ride quality. On the X3 M and X4 M it aims for a smoother, more settled ride on bad roads and long trips while still holding the car steady when you drive it hard.

What you get

  • Patented triple-stack spring design: dual-stacked springs with three rates, so one setup handles both comfort and hard driving.
  • Tuned for the specific vehicle, not a generic SUV kit.
  • Better stability and less harshness over rough pavement.
  • Fully adjustable, as the kit name states.
