AST Lowering Springs For BMW 3 318i/320i/330i/316D/318D/320D 07/2019-, Front 40 , Rear 35

The AST Lowering Springs are engineered to provide a refined balance between enhanced vehicle dynamics and everyday comfort. Manufactured using advanced Wafios coiling machines, these cold-coiled springs ensure precision and durability, meeting the highest standards expected in automotive performance parts. Designed specifically for BMW 3 Series models including 318i, 320i, 330i, 316D, 318D, and 320D from 07/2019 onward, these springs offer a tailored fit that maintains the integrity of your vehicle’s suspension system.

By lowering the vehicle’s center of gravity—40 mm at the front and 35 mm at the rear—these springs contribute to improved handling characteristics, reduced body roll, and a more confident driving experience without significantly compromising ride comfort. The progressive spring design optimizes suspension response, allowing for enhanced stability during cornering and braking while preserving the smoothness expected from OEM components.

AST’s commitment to quality is reflected in the use of premium materials and meticulous manufacturing processes, ensuring long-lasting performance and reliability. These springs are covered by a lifetime warranty against breaking, providing assurance and peace of mind for discerning drivers who demand both performance and durability from their suspension upgrades.

It is important to note that these lowering springs are not suitable for four-wheel-drive (4WD) vehicles. Additionally, vehicles equipped with M-Sport or Adaptive M-Sport suspension systems will experience approximately 10 mm less lowering compared to standard configurations.
