The AST Lowering Springs for the 2015 and newer Audi A4 B9 models 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 metal consistency by AST engineers. Each spring undergoes a precise cold winding process followed by heat treatment to enhance hardness and minimize internal stresses. The springs are then individually shot peened, phosphate treated, and powder coated to ensure durability and longevity beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs provide a balanced ride quality with improved cornering stability and a lowered stance for a sportier look.

Designed specifically for the B9 Audi A4 from 2015 onward, these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). They serve as a direct replacement for factory springs, offering a performance upgrade suitable for street driving and spirited handling. Installation is straightforward, fitting seamlessly into the existing suspension setup without modifications. The kit includes the necessary springs, ensuring a complete upgrade. Ideal for enthusiasts seeking improved handling, reduced ride height, and enhanced vehicle stance, these springs deliver consistent performance and durability for daily driving or spirited road use.
