The AST Suspension Lowering Springs for the 2006-2013 BMW 3 Series E93 are high-performance coil springs designed to improve handling and aesthetics. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and consistency. Each spring undergoes a rigorous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The springs are then phosphate treated and powder coated to ensure durability and longevity, surpassing the typical lifespan of the vehicle. Featuring progressive rates on most applications, these springs provide a balanced ride with improved cornering and reduced body roll, making them ideal for enthusiasts seeking both performance and style.

Designed specifically for the 2006-2013 BMW 3 Series Cabrio models (E93), these lowering springs lower the vehicle by approximately 30mm at the front and 15mm at the rear, offering a more aggressive stance without compromising ride quality. They are a direct replacement for the factory springs, intended for street and performance driving. The kit includes four springs, tailored to fit the specified chassis and engine configurations, ensuring proper fitment and performance. Suitable for daily driving, spirited street use, or track days, these springs enhance handling characteristics while maintaining comfort and reliability. Installation is straightforward for those familiar with suspension work, providing a reliable upgrade for BMW enthusiasts.
