AST Lowering Springs For BMW 3/R 320i/323i/325/i 05/1986-05/1993, Front 40 , Rear 40

The AST Lowering Springs are precisely engineered to enhance the driving dynamics of your BMW 3/R 320i/323i/325/i (05/1986-05/1993) by effectively lowering the vehicle's center of gravity. Manufactured using state-of-the-art Wafios coiling machines, these springs offer a superior cold-coiled construction that ensures durability and consistent performance over time. Designed to be a direct replacement for the original equipment manufacturer (OEM) springs, they maintain much of the ride comfort expected from factory components while delivering improved handling and stability.

AST’s commitment to quality is evident in the use of premium materials and precise engineering tailored specifically for each vehicle model. The progressive spring design provides a balanced reduction in ride height—40 mm at the front and 40 mm at the rear—resulting in enhanced cornering response and a more aggressive stance without compromising everyday usability. These springs are suitable for a wide range of applications, reflecting AST’s extensive experience with over 2500 vehicle models since 1966.

In addition to performance benefits, the AST Lowering Springs come with a lifetime warranty against breaking, underscoring their reliability and the brand’s confidence in their product. This warranty ensures long-term peace of mind for professional and enthusiast drivers alike.

Please note that these springs are not compatible with M-models, S4 models, or vehicles equipped with Audi sport chassis.
