KW V4 Tri-Adjustable Suspension Package for BMW F80 M3 and F82 M4, including Competition and CS

Unlock giant-killing handling and control on your F8x platform with the KW Variant 4. This premium damper and spring package brings three-way damping control, precise ride height adjustment and stainless construction to your BMW performance build. Whether you spend most of your time on British B-roads or chasing lap times, this kit delivers composure, grip and confidence without sacrificing everyday usability.

With separate adjusters for rebound, low speed bump and high speed bump, you can tailor balance, traction and comfort to your driving style. The result is sharper turn in, flatter cornering, improved traction out of bends and a planted feel over rough tarmac. Built with stainless steel struts for long term corrosion resistance and consistent performance, and supplied with aluminium top mounts depending on vehicle application, this is a serious upgrade for fast road and track use.

Key features

  • Three-way damping control for fine tuning on street and circuit
  • Independent adjusters
    • Rebound: 16 clicks for steering precision and comfort control
    • Low speed bump: 6 clicks for chassis balance and body control
    • High speed bump: 14 clicks for stability over bumps and kerbs
  • Stainless steel struts for durability in all weather
  • Ride height adjustable for stance, clearance and aero balance
  • Aluminium top mounts provided on certain applications
  • Manufacturer part approval available in documentation

Real world results

We have installed and run this kit on our own cars and countless customer builds. Feedback is consistently outstanding. Drivers report tighter body control, faster direction changes, stronger braking stability and a more composed ride on poor UK roads when correctly set.
