About this part

Product Details

If you're looking to give your 2004-2010 BMW 5 Series with air suspension a more aggressive stance and improved handling, these AST Lowering Springs are a solid option. They're designed to reduce your vehicle's center of gravity, which can make a noticeable difference in how the car feels during cornering. The goal here is to lower the car without sacrificing too much of the comfortable ride you expect from the factory setup.

These springs are built using premium materials and are cold-coiled on Wafios coiling machines, which are known for their precision. This means you're getting a well-built part that's made to last. The progressive design helps strike that balance between lowering the car and enhancing its performance characteristics. They're a direct replacement for your stock springs, making the installation process more straightforward.

AST backs these springs with a lifetime warranty against breaking, so you can install them with confidence. They're a popular choice for BMW owners looking for that subtle drop and a more connected feel to the road.
