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 handpicked by AST engineers for their consistent quality and durability. Each spring undergoes a meticulous 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 longevity beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs provide a balanced ride quality with improved cornering stability and a lowered stance for a sportier look.

Designed specifically for 2005-2012 BMW 3 Series E90 models, these springs are suitable for vehicles equipped with Electronic Damping Control (EDC). They serve as an effective upgrade for enthusiasts seeking enhanced handling and a lowered ride height, typically reducing the front by 30mm and the rear by 20mm. Installation is a direct bolt-on replacement for the factory springs, making them suitable for street and performance driving. The kit includes the set of front and rear springs, offering a comprehensive solution for suspension enhancement. These springs are ideal for daily drivers, street enthusiasts, and track-day participants aiming for improved vehicle dynamics and a refined appearance.
