If you’re looking to take your ride to the next level, the KW (H.A.S) Height Adjustable Spring kits are a solid choice. Gone are the days of being stuck with a fixed lowering height. With these kits, you can actually tweak your vehicle's ride height even after installation, which is a game-changer for those of us who like to fine-tune our setups. It’s like having your cake and eating it too—you get that aggressive stance while still maintaining the comfort and handling of your factory suspension.

What I really appreciate about the KW H.A.S. system is how it enhances the steering response. You can feel the difference right away; it’s like your car becomes more alive and agile. And if you’ve got those driver assistance features or an electronic suspension, don’t worry. Everything works together seamlessly. No need to sacrifice comfort or tech for style.

These springs are crafted from high-quality chrome-silicon steel, which means they’re built to last. KW has put a lot of thought into the spring rates, tuning them specifically for each original equipment (OE) suspension damper and wheel load. This isn’t just some one-size-fits-all setup; it’s tailored to fit your ride perfectly. Plus, they include bump stops with a dust protection system, which is a nice touch. It helps keep your factory suspension safe from the grime and debris that can cause wear and tear over time.

One of the standout features of the KW H.A.S kit is the continuous ride height adjustment. You can dial in the height to your liking, something you just can’t do with traditional lowering springs. The included dust protection elements and spring perches are designed to let you lower your vehicle as much as technically possible, usually limited by those factory dampers. So, you’re not just getting a drop; you’re getting a setup that feels sporty without sacrificing the driving dynamics that make your car enjoyable.

Every KW product is tested rigorously, including on the Nurburgring Nordschleife, so you know you’re getting something that’s been proven in the real world. The attention to detail in the engineering is evident, and that’s what sets KW apart.
