The AST 20mm D&S Springs are high-performance lowering springs designed for the Audi A4 Avant models from 2008 to 2015. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and metal consistency. Each spring undergoes a 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 that surpasses the vehicle’s lifespan. Featuring progressive rates on most applications, these springs improve handling, stability, and stance while maintaining ride comfort. Their robust construction and treatment processes deliver long-lasting performance and resistance to wear.

Designed specifically for 2008-2015 Audi A4 B8 models equipped with various engines including 3.2 FSi, 2.7 TDi, and 3.0 TDi, these springs serve as an effective lowering upgrade. They are compatible with vehicles featuring Electronic Damping Control (EDC), providing a tailored fit for enhanced driving dynamics. The springs are a direct replacement for factory units, offering improved handling and a sportier appearance without compromising ride quality. Installation is straightforward for those familiar with suspension work, and the kit includes the necessary springs for the front and rear. Ideal for street and spirited driving, these springs deliver a performance-oriented stance and improved cornering capabilities.
