About this part

Product Details

If you're looking to give your 07/2019- BMW 3 Series (G21) 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 car's center of gravity by about 40mm in the front and 35mm in the rear. This change can make a noticeable difference in how the car feels during cornering.

AST builds these springs using premium materials on Wafios coiling machines, which are well-known for their precision. The progressive spring design is key here; it helps balance the desire for a lower ride height with the need to keep things comfortable for daily driving, so you don't sacrifice too much of the OEM feel. They've developed these specifically for each vehicle application, aiming for a direct fit without major modifications.

These springs come with a lifetime warranty against breaking, which is a good sign of their build quality. While they're designed to work with your existing suspension components, it's always a good idea to have your alignment checked after installing lowering springs to ensure everything is set correctly.
