Product Details

AST is a well-known name for suspension parts, and these lowering springs are a great example of their work. If you're looking to give your 2019 or newer Audi S4 a lower stance and a more planted feel, these springs are designed to do just that. They're built to replace your factory springs directly, making the installation straightforward.

These springs are cold-coiled on Wafios coiling machines, which are considered top-tier for spring manufacturing. This process helps ensure a consistent and durable product. The progressive design means they offer a good balance – they'll lower your car's center of gravity for improved handling, but they're also engineered to keep a comfortable ride, similar to what you'd expect from the original equipment. You get a noticeable drop of 30mm in the front and 25mm in the rear, which really changes the car's look and feel.

Because they're made with such care, AST backs these springs with a lifetime warranty against breaking. This gives you confidence that they're built to last.
