AST Suspension Lowering Springs (50mm/40mm TUV) - 2000-2007 BMW 3 Series 4CYL Cabrio (E46)

The AST Suspension Lowering Springs for the 2000-2007 BMW 3 Series E46 Cabrio 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 metal 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. These springs feature progressive rates on most vehicles, providing improved handling, stability, and a sportier stance while maintaining ride comfort and durability.

Designed specifically for the E46 chassis from 2000 to 2007, these springs are compatible with models equipped with 4-cylinder engines and are suitable for street and spirited driving. They serve as direct replacements for the factory springs, offering a performance upgrade that enhances cornering and overall vehicle responsiveness. Installation is straightforward as they are bolt-on components, and the kit includes the necessary springs for both the front and rear. Ideal for enthusiasts seeking a lowered stance and improved handling, these springs are engineered to withstand daily driving conditions and track use alike.
