What is the ride height reduction for these springs?

These AST lowering springs will reduce the ride height by approximately 20mm in both the front and rear of your vehicle. This provides a lower center of gravity and a sportier stance.

Are these springs compatible with my original shocks?

These springs are designed as a direct replacement for your OEM springs and are intended to work with your vehicle's original shocks. However, for optimal performance and longevity, it is often recommended to pair lowering springs with performance or upgraded shocks.

What does the lifetime warranty cover?

AST offers a lifetime warranty against breaking for these lowering springs. This ensures that the springs are protected against manufacturing defects that could cause them to fail structurally.

About this part

Product Details

These AST lowering springs are cold-coiled on Wafios coiling machines, a detail that matters for achieving a consistent spring rate and ride quality. They are designed to replace your BMW 4 Series' original springs directly, aiming to lower your vehicle's center of gravity. This adjustment can lead to improved handling characteristics, especially during cornering, without sacrificing too much of the comfortable ride you expect from the factory setup. The progressive design helps balance a lower stance with enhanced performance.

Developed specifically for each vehicle application, these springs are built from well-selected materials to ensure durability. The 20mm drop front and rear offers a noticeable change in appearance and handling. They are a solid option if you're looking to give your BMW 4 Series a sportier look and feel. These springs come with a lifetime warranty against breaking, giving you confidence in their longevity.
