The AST Suspension Lowering Springs for the 2006-2013 BMW 3 Series E93 are high-performance coil springs designed to lower the vehicle's ride height by 45mm front and 30mm rear. 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, followed by shot peening, phosphate treatment, and powder coating to ensure durability and longevity. The progressive rate design on most applications provides improved handling, stability, and a lowered stance, enhancing both aesthetics and performance.

These springs are specifically engineered for the E93 chassis, covering model years from 2006 to 2013, including variants like 335i, 325D, and 330D Cabrio. They are suitable for street and performance driving, offering a direct bolt-on upgrade that maintains ride quality while reducing body roll and improving cornering response. Installation is straightforward, replacing factory springs without modifications. The kit includes the set of lowering springs, providing a comprehensive upgrade for enthusiasts seeking improved handling and a sportier appearance on their BMW 3 Series Cabrio.
