How much will these springs lower my BMW 6 Series?

These AST lowering springs are designed to provide a 45mm drop on the front and a 40mm drop on the rear for your BMW 6 Series.

Do I need any other parts to install these springs?

While these springs are a direct replacement for your OEM springs, it's often recommended to have your wheel alignment checked and adjusted after installing lowering springs to ensure proper tire wear and handling.

What does a progressive spring rate mean?

A progressive spring rate means the spring becomes stiffer as it compresses. This design helps provide a comfortable ride during normal driving but offers more support when you encounter harder cornering or bumps.

Product Details

AST makes these lowering springs for the 2004-2010 BMW 6 Series. They reduce your vehicle's center of gravity, which can help with handling, without sacrificing too much of the comfort you expect from stock springs. These are a direct replacement for your factory springs.

These springs are cold-coiled on Wafios machines, known for quality spring manufacturing. They have a progressive design, meaning they get stiffer as they compress, which helps balance lowering the car with maintaining a decent ride quality.
