The AST Suspension Lowering Springs for the 2015+ Audi A4 B9 are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, followed by shot peening, phosphate treatment, and powder coating to ensure longevity. Featuring progressive rates on most vehicles, these springs provide a smoother ride while lowering the vehicle's stance by 30mm, enhancing cornering stability and visual appeal. The construction and treatment processes ensure they withstand harsh conditions and maintain performance over time.

Designed specifically for the 2015 and newer Audi A4 Sedan models with automatic gear and 2.0 TFSI or TDI engines, these springs are compatible with Electronic Damping Control (EDC) systems. They serve as a direct replacement for factory springs, offering a lowered ride height that improves handling and reduces body roll during aggressive driving. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary springs for both front and rear. Ideal for street enthusiasts seeking a balance of performance and comfort, these springs are suitable for daily driving, spirited street use, and light track days, providing a reliable upgrade to enhance vehicle dynamics.
