About this part

Product Details

If you're looking to give your BMW 4 Series (starting from 07/2021) a lower stance and improved handling, these AST Lowering Springs are a solid option. They're designed to replace your factory springs directly, lowering your car's center of gravity by about 40mm in both the front and rear. This change can make a noticeable difference in how your car feels during spirited driving.

AST builds these springs using well-made materials, cold-coiled on Wafios machines, which are known for their precision. The progressive design means they offer a good balance – you get the benefit of a lower ride height and potentially sharper handling without sacrificing too much of the comfortable ride you expect from the original equipment. They're developed specifically for each vehicle application to ensure a proper fit and function.

These springs come with a lifetime warranty against breaking, so you can install them with confidence. Keep in mind that lowering springs will change your vehicle's ride characteristics, and it's always a good idea to have them installed by a professional to ensure proper alignment afterwards.
