The AST Lowering Springs for the BMW 3 Series E90 (2005-2012) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are carefully selected by AST engineers for their durability and metal consistency. Each spring undergoes a precise manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening. The springs are then phosphate treated and powder coated, ensuring long-lasting corrosion resistance and a clean appearance. Featuring progressive rates on most vehicles, these springs provide a balanced ride quality with improved cornering stability and lowered stance, making them ideal for enthusiasts seeking enhanced performance and visual appeal.

Designed specifically for 2005-2012 BMW 3 Series E90 models, these springs are a direct replacement upgrade for the factory suspension. They are compatible with vehicles equipped with Electronic Damping Control (EDC), offering a tailored lowering experience of approximately 45mm in the front and 30mm in the rear. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary springs for both front and rear positions. These springs are suitable for street driving and spirited daily use, providing improved handling without sacrificing ride comfort. They serve as a durable, performance-oriented upgrade for BMW owners looking to enhance their vehicle’s stance and driving dynamics.
