What is the drop height for these springs?

These AST lowering springs are designed to provide a 30mm drop for both the front and rear of your vehicle.

Are these springs compatible with my M4 Competition model?

Yes, these springs are listed as compatible with the 3.0L and 3.0 Competition variants of the BMW M4 from 2014-2020.

What does a progressive spring design mean?

A progressive spring design means the spring rate changes as it compresses. This allows for a softer initial ride, but gets stiffer under load, helping to balance comfort and performance.

Product Details

AST makes these lowering springs for the BMW M4. They lower your car's center of gravity, which can help with handling, while keeping a comfortable ride similar to the original springs.

These springs are a direct replacement for your factory springs. They are cold-coiled on Wafios machines, which are well-known for making quality springs. The progressive design means they balance lowering the car with improving performance.
