Product Description

 

 

Upgrade your G8X-platform BMW M2, M3, or M4 with the KW Height Adjustable System (H.A.S.) — a premium suspension lowering solution that combines the benefits of conventional lowering springs with the tunability of adjustable ride height. Unlike traditional fixed springs, this kit lets you fine-tune your vehicle’s ride height even after installation, giving you total control over stance, ground clearance, and suspension balance. Engineered with vehicle-specific spring rates and threaded height perches, the system enhances handling dynamics while maintaining compatibility with your factory electronic suspension — preserving adaptive damping and driver assistance features. The result is a more responsive, planted driving feel with a sharper look and optimized performance.

Fitment Notes

  • OE fitment for BMW G87 M2 (2023+), G80 M3 (2021+), and G82/G83 M4 (2021+) chassis.

  • Compatible with both RWD and AWD (xDrive) variants. 

  • Designed to work with standard and adaptive electronic dampers — no need to deactivate or remove factory suspension electronics.

  • Returns not accepted due to the bespoke nature of suspension components; professional installation is recommended.

Included

  • Four (4) height-adjustable lowering springs with threaded perches (front & rear). 

  • Vehicle-specific progressive spring rates balanced to your damper and chassis load.

  • Threaded ride-height adjusters for continuous height tuning.

  • Strengthened bump stops and dust covers for long-term durability.

  • Mounting hardware and installation instructions.

Product Specs

  • Installation: Uses factory shock absorbers (no coilover shocks required).

  • Ride Height Adjustment: Continuous adjustment via threaded perches (adjust after installation). 

  • Material: High-quality chrome-silicon steel springs with protective coatings.

  • Lowering Range (approximate, varies by model):

    • Front: ~0.4″ to 1.2″ (vehicle-dependent)

    • Rear: ~0.2″ to 0.8″ (vehicle-dependent)

  • Compatibility: Preserves full function of adaptive/smart suspension electronics with proper fitment.

Product Features

  • Progressive spring rates tailored to your specific BMW chassis for balanced handling and comfort.

  • Retains factory adaptive damping and electronics — keeping comfort and performance modes fully functional.
