The AST Suspension Lowering Springs for the 1998-2005 BMW 3 Series (E46) are high-performance coil springs designed to improve handling and aesthetics. 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 rigorous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening for fatigue resistance. The springs are phosphate treated and powder coated to ensure durability and longevity, even beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs provide a balanced ride quality with improved cornering stability and lowered stance.

Designed specifically for the E46 chassis from 1998 to 2005, these springs are suitable for 4-cylinder sedans seeking a moderate drop of approximately 50mm front and 40mm rear. They serve as a direct replacement for stock springs, offering enhanced handling performance without sacrificing ride comfort. Installation is straightforward, compatible with factory suspension components, and ideal for street and spirited driving. The kit includes the set of lowering springs, ensuring a complete upgrade for enthusiasts looking to improve their BMW's stance and handling characteristics.
