The AST Lowering Springs for BMW G30 5 Series models 520i, 530i, 518D, and 520D (09/2016–07/2023) represent a high-quality solution designed to enhance vehicle dynamics by lowering the center of gravity while maintaining a comfortable ride. Manufactured with precision on advanced Wafios coiling machines, these cold-coiled springs ensure consistent performance and durability. Their progressive design allows for a refined balance between sportier handling and ride comfort, making them an ideal upgrade for drivers seeking improved road feel without compromising everyday usability.

Engineered specifically for these BMW models, the AST springs provide a front and rear lowering of 45 mm, effectively reducing body roll and improving stability during cornering. This targeted lowering enhances the vehicle’s stance and aerodynamic profile, contributing to a more confident driving experience. The springs are crafted from premium materials, assuring long-term reliability and resistance to fatigue. Furthermore, AST offers a lifetime warranty against breaking, underscoring their commitment to quality and customer satisfaction.

Installation of these lowering springs is straightforward since they serve as direct replacements for the OEM springs, preserving the original suspension geometry and ensuring compatibility with the vehicle’s existing components. The springs are suitable for standard suspension setups; however, it is important to note that they are not compatible with four-wheel-drive (4WD) vehicles. Additionally, vehicles equipped with M-sport suspension may experience approximately 10 mm less lowering than the specified values.
