The AST Lowering Springs are engineered to provide a precise and reliable solution for lowering your BMW 3 Series (316i/318i/320i/328i/316D/318D/320D) models from 01/2012 to 01/2019. Manufactured using advanced cold-coiling technology on premium Wafios machines, these springs ensure consistent quality and durability. Designed to reduce the vehicle’s center of gravity by 40 mm at both the front and rear, they enhance handling and stability without significantly compromising ride comfort.

Crafted with meticulous attention to detail, the AST Lowering Springs offer a progressive spring rate that balances performance improvements with daily driving comfort. These springs act as a direct replacement for the original equipment manufacturer (OEM) springs, maintaining compatibility with your vehicle’s suspension system. The result is improved cornering response, reduced body roll, and a sportier stance that elevates both aesthetics and driving dynamics.

AST’s commitment to quality is reflected in the lifetime warranty against breaking, providing assurance and reliability for long-term use. The springs are suitable for a wide range of driving conditions, making them an excellent choice for enthusiasts seeking enhanced performance without sacrificing everyday usability.
