AST Suspension Lowering Springs (50mm/40mm TUV) - 1998-2005 BMW 3 Series 320D/6CYL 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. Crafted from premium high tensile chromium-silicone wire, these springs are handpicked for their quality and consistency. The manufacturing process involves cold winding, heat treatment to enhance hardness and reduce internal stresses, followed by shot peening, phosphate treatment, and powder coating to ensure durability and longevity beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs improve handling, stability, and aesthetics by reducing body roll and lowering the center of gravity, resulting in a more aggressive stance and enhanced driving dynamics.

Designed specifically for the E46 chassis BMW 3 Series sedans with 6-cylinder engines, these springs are suitable for street and performance driving. They serve as direct replacements for stock springs, providing a lower ride height without compromising ride quality or comfort. The kit includes the set of springs necessary for both front and rear suspension, ensuring a straightforward bolt-on installation. Compatible with vehicles equipped with Electronic Damping Control (EDC), these springs are ideal for enthusiasts seeking improved handling and a sportier appearance while maintaining everyday drivability.
