AST Suspension Lowering Springs (25mm/15mm TUV) - 1998-2001 Audi A4 2.7TT (S4/B5)

The AST Suspension Lowering Springs for the 1998-2001 Audi A4 2.7TT (S4/B5) are high-performance coil springs designed to improve handling and aesthetics by reducing ride height. Constructed from high tensile chromium-silicone wire, these springs are carefully handpicked for quality and consistency. Each spring undergoes a precise manufacturing process, including cold winding, heat treatment to enhance hardness, and shot peening to reduce internal stresses. The springs are then phosphate treated and powder coated for durability and corrosion resistance, ensuring long-lasting performance. Featuring progressive rates on most vehicles, these springs provide a smoother ride while enhancing cornering stability and overall vehicle stance.

Designed specifically for the B5 chassis Audi A4 from 1998 to 2001, these springs are compatible with models equipped with the 2.7TT engine and S4 trim. They serve as a direct replacement for factory springs, offering a lowered ride height of 25mm at the front and 15mm at the rear to improve handling dynamics and visual appeal. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the springs only. Ideal for street performance and daily driving, these springs help optimize vehicle balance and responsiveness without compromising ride comfort.
