What is the main benefit of installing these lowering springs?

These springs lower your vehicle's center of gravity by about 30mm in the front and 25mm in the rear. This can lead to improved handling and a more aggressive stance for your BMW 4 Series.

Will these springs make my car ride too stiff?

AST uses a progressive spring design that aims to balance ride comfort with performance. While they will be firmer than stock for better handling, they are developed to retain a comfortable ride for daily driving.

What does the lifetime warranty cover?

The lifetime warranty covers the springs against breaking. This provides peace of mind for the duration of your ownership, ensuring the springs will hold up under normal driving conditions.

Product Details

If you're looking to give your BMW 4 Series (starting November 2020) 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 the front and 25mm in the rear. This change can make a noticeable difference in how the car feels during spirited driving.

AST builds these springs using premium materials on Wafios coiling machines, which are known for their precision. The progressive spring design is key here; it means they offer a firmer ride for better performance when you're cornering hard, but they still maintain a good level of comfort for everyday driving, similar to what you'd expect from the original parts. This balance is what makes them a popular choice for drivers who want a sportier look and feel without sacrificing too much ride comfort.

These springs are backed by a lifetime warranty against breaking, so you can install them with confidence. They're a direct replacement, meaning no major modifications are usually needed for installation, but as always, refer to the manufacturer's instructions for the best results.
