The AST 30/30mm Lowering Springs for the BMW 4 Series F32 (2013-2017) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are selected 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 for fatigue resistance. 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 style.
Designed specifically for 2013 and newer BMW 4 Series F32 models, these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). They serve as a direct replacement for factory springs, offering a lowered ride height of approximately 30mm front and rear for a more aggressive look and improved handling dynamics. Installation is straightforward for those familiar with suspension upgrades, and the springs are suitable for street use, track days, or spirited driving. The kit includes the set of springs, with no additional components required, ensuring a hassle-free upgrade. These springs are perfect for drivers seeking a combination of performance, durability, and aesthetic enhancement on their BMW F32.
