ST XA Adjustable Suspension Kit for BMW F20 F21 F23 F30 F32 F36 RWD

Transform the way your BMW drives with the ST XA adjustable suspension kit. Built with KW know-how and designed for rear wheel drive F-series platforms, this complete spring and damper package gives you precise rebound tuning and on-car ride height control so you can dial in stance, grip and comfort for fast road and occasional track use.

Why this upgrade works

  • Rebound tuning lets you switch from compliant daily ride to taut, sporty response in seconds for confident cornering and reduced body movement.
  • KW engineering inside for consistent damping, excellent seal integrity and long-term reliability.
  • Zinc plated steel damper bodies with corrosion protection for year-round durability in the UK climate.
  • Threaded height adjustment for a clean drop and perfect fitment with your wheel and tyre setup.
  • Lower centre of gravity for improved traction, sharper steering feel and composed braking.

Lowering range

  • Front drop: approx 25 to 50 mm
  • Rear drop: approx 30 to 56 mm
