If you're looking to take your ride to the next level, the KW (H.A.S) Height Adjustable Spring Kit is a solid choice. I’ve had my hands on these springs, and let me tell you, they’re a game changer. Unlike those old-school lowering springs that lock you into a fixed height, this kit gives you the freedom to adjust your vehicle's ride height even after installation. That means you can tweak it to your liking as you go, which is pretty cool.

Not only does your car get that aggressive stance that turns heads, but the handling also gets a serious upgrade. With the KW H.A.S. system, the steering feels sharper and more responsive, making every drive a bit more engaging. Plus, if your ride has factory adaptive or electronic suspension, you won’t lose any of those features. They work seamlessly with KW's setup, so you get the best of both worlds.

One of the standout features of these springs is the high-quality chrome-silicon steel they’re made from. Each spring is tuned to match your vehicle's original dampers and wheel load, so you know you're getting a custom fit. KW doesn’t just throw these together; they put in the research and development, testing them on the infamous Nürburgring Nordschleife and in their 7-post Driving Dynamic Test Center. It’s not just talk—these springs are engineered for performance.

Installation is straightforward, and once you’re set up, you can adjust the ride height with millimeter precision. This means you can dial in the perfect look and feel without sacrificing the driving dynamics. The kit even includes bump stops with dust protection to keep your factory suspension safe from the wear and tear of everyday driving. It’s all about longevity and performance here.

And let’s not forget about the warranty. KW backs their products with a limited lifetime warranty, so you can hit the road with confidence knowing they’ve got your back.
