AST Suspension Lowering Springs (50mm/40mm TUV) - 1998-2005 BMW 3 Series 330D Sedan (E46)

The AST Suspension Lowering Springs for the 1998-2005 BMW 3 Series (E46) are high-performance coil springs designed to lower the vehicle's ride height by 50mm front and 40mm rear. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and consistency. The springs undergo a rigorous 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 durability and corrosion resistance. Featuring progressive spring rates on most vehicles, these springs improve handling, stability, and aesthetics while maintaining ride comfort and ride quality.

Designed specifically for the E46 chassis from 1998 to 2005, these springs are suitable for BMW 3 Series sedans equipped with the 330D engine. They serve as a direct replacement for stock springs, providing a lowered stance and improved performance for street and spirited driving. Installation is straightforward, compatible with the vehicle's existing suspension components, and ideal for enthusiasts seeking a balance of lowered aesthetics and enhanced handling. The kit includes the set of lowering springs, ensuring a complete upgrade for your vehicle’s suspension system.
