KW H.A.S. for BMW F83 M4

Starting with high-strength springs made from multi-coated chrome-silicon steel, KW's Height Adjustable Spring (H.A.S.) kit for your 2015-2020 BMW M4 offers a significant upgrade over standard lowering springs. Unlike fixed lowering springs, this system allows you to fine-tune the ride height of each corner with millimeter precision, even after installation. This means you can dial in the perfect stance for your M4, achieving a more dynamic look without sacrificing the car's inherent driving dynamics.

KW engineers these springs specifically to work with your M4's factory dampers, whether they're standard or electronic adaptive. The spring rates are carefully matched to the OE suspension's characteristics, ensuring improved steering response and a sportier feel without compromising the vehicle's performance-oriented handling. This kit also includes application-specific bump stops and dust protection systems, safeguarding your factory suspension components from road debris and wear. You get the benefits of a coilover-like adjustable ride height while keeping all your factory electronic suspension systems fully operational.

This H.A.S. kit is designed to provide a sporty and harmonious driving experience, rigorously tested on the Nurburgring Nordschleife and in KW's own 7-post driving dynamics test center. It's a well-built solution that lets you achieve a personalized look and feel for your M4 while maintaining the integrity and functionality of its advanced factory suspension.
