These MMX springs lower the X3 M and X4 M by 30 mm at both ends, closing up the wheel-arch gap the cars leave the factory with. A lower center of gravity cuts body roll and sharpens turn-in, while progressive rates keep the low-speed ride comfortable.

What you get

  • 30 mm drop front and rear for an even stance.
  • Progressive spring rates that stay compliant around town and firm up when you push through corners.
  • Works with static or dynamic dampers, so it suits cars with or without adaptive suspension.
  • Designed specifically for the F97 chassis.
