About this part

Product Details

Cold-coiled on Wafios coiling machines, these AST lowering springs are built to reduce your BMW 4 Series' center of gravity. This set is specifically developed for the 07/2021 and newer models, offering a 35mm drop in the front and a 30mm drop in the rear. The goal here is to give you a sportier stance and potentially improved handling without sacrificing the comfortable ride you expect from the original equipment.

These springs are designed as a direct replacement for your factory springs, making installation straightforward. Their progressive design is key to balancing a lower ride height with enhanced performance. You get a more aggressive look and a lower center of gravity, which can make a notable difference in how the car feels during spirited driving, all while aiming to keep the ride quality close to stock.

AST backs these springs with a lifetime warranty against breaking, so you can install them with confidence. They are a well-built option for BMW 4 Series owners looking to subtly change their car's stance and driving dynamics.
