Description
The KW H.A.S. (Height Adjustment System) spring kit for the 2021+ BMW M4 Convertible offers a versatile solution for drivers seeking to customize their vehicle’s ride height without sacrificing comfort or safety. Designed specifically for the G82 and G83 models, this system allows for seamless height adjustments even after installation, providing a tailored driving experience that combines sporty aesthetics with practical functionality.
Constructed from high-strength chrome-silicon steel, the springs are coated for durability and long-term performance. The kit features vehicle-specific spring rates that are carefully tuned to work harmoniously with the factory dampers, ensuring that the vehicle maintains precise handling, responsiveness, and stability. The included high-quality elastomer bump stops and dust protection system safeguard your suspension components from road grime, debris, and wear, extending the lifespan of your suspension setup.
Unlike traditional lowering springs, the KW H.A.S. system offers continuous ride height adjustment through a user-friendly mechanism, allowing you to fine-tune your vehicle’s stance with millimeter precision. This adjustability enables a more aggressive or comfortable ride profile depending on your preferences, without compromising factory electronic suspension functions. All adjustments are made within tested ranges to maintain optimal performance and safety.
As with all KW suspension products, each kit undergoes rigorous testing, including real-world validation on the Nürburgring Nordschleife and the KW 7-post Driving Dynamic Test Center. The system maintains full operational compatibility with advanced driver assistance systems and factory electronic suspension features, ensuring a harmonious integration with your vehicle’s existing systems.
Manufactured in Germany, KW has been a pioneer in suspension innovation for over two decades, trusted by automotive manufacturers, tuners, and motorsport professionals worldwide. The KW H.A.S. kit is backed by a limited lifetime warranty, offering peace of mind along with superior ride quality, sporty handling, and customizable height adjustment for your BMW M4 Convertible.
