What is the ride height difference with these springs?

These AST lowering springs will lower your BMW 4 Series xDrive by approximately 30mm in the front and 25mm in the rear. This change helps reduce the vehicle's center of gravity.

Are these springs compatible with my standard BMW shocks?

These springs are designed as direct replacements for your OEM springs and are intended to work with your factory shock absorbers. However, for optimal performance and longevity, it's often recommended to pair lowering springs with performance-oriented dampers.

What does the lifetime warranty cover?

The lifetime warranty provided by AST covers the springs against breaking. This ensures you have peace of mind regarding the durability of the springs themselves.
