The AST Suspension Lowering Springs for the 2005-2012 BMW 3 Series (E90) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are handpicked by AST engineers for their quality and metal consistency. 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 ensure durability and corrosion resistance, allowing these springs to outlast the vehicle itself. Featuring progressive rates on most applications, they provide a balanced ride quality with improved stability during cornering and aggressive driving.

Designed specifically for the E90 chassis, these springs fit 2005-2012 BMW 3 Series sedans including 316i, 318i, and 320i models. They are intended as a direct replacement for factory springs, offering a lowered stance of 30mm at the front and 20mm at the rear to enhance the vehicle's visual appeal and handling performance. Suitable for street and spirited driving, these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). Installation is straightforward as bolt-on replacements, and the kit includes the necessary springs for both front and rear. They are ideal for enthusiasts seeking a durable, high-quality upgrade to improve ride dynamics and vehicle stance.
