The AST Suspension Lowering Springs for the 2006-2013 BMW 3 Series E93 are high-performance coil springs designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are carefully selected by AST engineers for their strength and consistency. Each spring undergoes a precise manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The springs are phosphate treated and powder coated to ensure durability and resistance to corrosion, providing long-lasting performance. Featuring progressive rates on most vehicles, these springs offer a balanced ride quality with improved stance and reduced body roll, making them ideal for enthusiasts seeking enhanced driving dynamics.

Designed specifically for the E93 chassis from 2006 to 2013, these springs are compatible with BMW 320i and 320D Cabrio models. They serve as a direct replacement for stock springs, lowering the vehicle by approximately 30mm at the front and 15mm at the rear, which enhances handling and visual appeal without compromising ride comfort. The springs are suitable for street use and spirited driving, providing improved cornering and stability. Installation is straightforward as they are bolt-on components, and the set includes the necessary springs for both front and rear. These springs are an excellent upgrade for drivers looking to optimize their BMW’s performance and appearance.
