AST Suspension Lowering Springs (50mm/40mm TUV) - 2000-2007 BMW 3 Series 320D/6CYL Cabrio (E46)

The AST Suspension Lowering Springs for the 2000-2007 BMW 3 Series (E46) are high-performance coil springs designed to lower the vehicle's ride height by 50mm at the front and 40mm at the rear. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The phosphate treatment and powder coating provide superior corrosion resistance and longevity, ensuring the springs maintain their performance over the vehicle's lifespan. Featuring progressive rates on most applications, these springs improve handling, stability, and cornering response while maintaining ride comfort.

Designed specifically for the E46 chassis BMW 3 Series models with 6-cylinder engines, including the 320D Cabrio, these springs are a direct replacement for stock components. They are suitable for street and spirited driving, offering a lowered stance that enhances the vehicle's aesthetic and aerodynamic profile. Installation is straightforward as they are bolt-on components compatible with existing suspension setups. The kit includes the springs themselves, with no additional components required. These springs are ideal for enthusiasts seeking improved handling and a sportier look without sacrificing daily drivability or durability.
