The AST 40mm/40mm Lowering Springs for the BMW 3 Series F30 (2012-2019) are high-performance suspension components 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 cold winding process followed by heat treatment to enhance hardness and minimize internal stresses. The springs are then individually shot peened, phosphate treated, and powder coated to ensure durability and longevity beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs provide a balanced ride quality, reducing body roll and lowering the vehicle's center of gravity for improved cornering performance.
Designed specifically for 2012-2019 BMW 3 Series F30 models, these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). They serve as a direct replacement for stock springs, offering a lowered stance of 40mm at the front and rear for a sportier look and enhanced handling. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary springs for both the front and rear. Ideal for street enthusiasts seeking improved handling and visual appeal, these springs are suited for daily driving, spirited street use, and track days, providing a reliable upgrade that maintains ride quality while delivering noticeable performance benefits.
