Do I need any other parts to install these lowering springs?

These springs are designed as a direct replacement for your OEM springs. However, it's always recommended to consult the manufacturer's installation instructions for any specific hardware or alignment requirements after installation.

What does the lifetime warranty cover?

The lifetime warranty covers the springs against breaking. This provides peace of mind for the lifespan of the product under normal use.

About this part

Product Details

If you're looking to give your 2021 and newer BMW 4 Series xDrive a more aggressive stance and improved handling, these AST Lowering Springs are a solid option. They're designed to directly replace your factory springs, lowering the vehicle's center of gravity by about 30mm in both the front and rear. This change can make a noticeable difference in how the car feels during spirited driving.

AST builds these springs using well-made materials on Wafios coiling machines, which are known for their precision. The progressive spring design is key here; it helps maintain a comfortable ride quality similar to your original springs, even with the lower ride height. This means you get the visual appeal and performance benefits of a lowered car without sacrificing too much comfort for daily driving.

These springs are specifically developed for your BMW 4 Series xDrive model, ensuring they fit right. They come with a lifetime warranty against breaking, so you can install them with confidence. While these springs lower the car, they are designed to work with your existing suspension components.
