The AST Lowering Springs for the BMW 5 Series G31 (2017 and newer) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are selected for their strength and consistency. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The phosphate coating and powder coating finish ensure durability and corrosion resistance, allowing these springs to outlast the vehicle itself. Featuring progressive rates on most applications, they provide a balanced ride quality with improved stability and cornering performance, making them an ideal upgrade for enthusiasts seeking a lowered stance and enhanced driving dynamics.

Designed specifically for 2016-2024 BMW 5 Series Touring models (G31), these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). They serve as a direct replacement for factory springs, offering a lowered ride height that enhances the vehicle's stance and handling characteristics. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary springs for both the front and rear. Suitable for street and spirited driving, these springs are perfect for owners looking to improve their vehicle’s appearance and performance without sacrificing ride comfort. They are an excellent choice for daily drivers and enthusiasts alike seeking a reliable, durable suspension upgrade.
