If you’re looking to give your ride a serious upgrade, the KW (H.A.S) Height Adjustable Spring Kit is definitely worth your attention. Unlike those conventional lowering springs that lock you into a fixed height, this kit lets you adjust your vehicle’s ride height even after installation. It's like having the best of both worlds—style and functionality wrapped up in one package.

Once you’ve got these springs installed, you’ll notice your car not only looks sharper but handles a whole lot better too. The steering response becomes more nimble, making every drive feel more engaging. And if you’ve got a factory adaptive or electronic suspension, don’t worry; all those driver assistance features and comfort perks still work like a charm with this setup. It’s designed to play nice with your existing systems.

KW really knows their stuff when it comes to engineering. The springs are crafted from high-quality chrome-silicon steel, with specific spring rates tailored for your OEM dampers and wheel load. This means you get a setup that feels just right, no matter how you drive. Plus, they include vehicle-specific bump stops with a dust protection system to keep your factory suspension safe from wear and tear caused by road grime. That’s a nice touch that shows they thought through the whole experience.

One of the best features is the seamless ride height adjustment. You can tweak each corner of your car with millimeter precision, unlike those old-school lowering springs that leave you stuck with whatever height you chose. And don’t think that sporty feel comes at the expense of comfort; KW has engineered this kit to maintain that harmonious driving experience, even on performance-oriented vehicles.

All of KW’s products are rigorously tested, including on the legendary Nürburgring Nordschleife, so you know you’re getting something that’s been put through its paces. If you’re serious about your driving experience, this kit is a solid investment.
