KW Variant 4 for BMW F80 M3 and F82 M4 - Triple Adjustable Height Adjustable Suspension - Part No. 3A7200AP

Unlock precision handling, confident road manners and track-day composure with the KW Variant 4 on your F80 M3 or F82 M4. This premium height adjustable spring and damper package brings independent rebound, low-speed compression and high-speed compression tuning so you can dial in ride, grip and body control for British roads and circuit work. Built with stainless steel strut bodies for corrosion resistance and long-term durability, it is a serious performance suspension upgrade for the F8x chassis.

We have fitted and set up this kit on our own projects and customer cars and the feedback is consistently outstanding for ride quality, steering feel and traction. If you are after a road friendly setup that can be sharpened for track sessions, this triple adjustable damper kit delivers.
