KW HAS Height Adjustable Spring Kit (Coilover Springs) for BMW M4 F82 Coupe, M4 F83 Convertible & M3 Cabrio 10/14-on - Lowering Springs, Retains EDC/Adaptive Dampers

KW HAS adjustable ride height sleeve springs for BMW M4 F82, M4 F83 and M3 Cabrio 10/14-on

Give your BMW M4 or M3 Cabrio the stance and precision it deserves with KW HAS adjustable sleeves. This premium height control solution works with your original shock absorbers, so you keep factory comfort and full functionality of Electronic Damper Control and adaptive suspension while gaining on-car ride height tuning for the perfect arch gap and road presence.

If you want coilover-style adjustability without changing your OE dampers, this is the upgrade. Threaded perches allow you to fine tune the drop after installation, improving turn in, body control and stability while maintaining everyday refinement. We have installed this setup many times and both our team and our customers love the transformation in both look and driving feel.
