The AST Suspension Lowering Springs for the 2014+ BMW 4 Series (F36) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness, and shot peening to reduce internal stresses. The powder coating and phosphate treatment ensure long-lasting corrosion resistance, making them a reliable upgrade for enthusiasts seeking improved stance and cornering capabilities. Featuring progressive rates on most vehicles, these springs provide a balanced ride quality while lowering the vehicle by approximately 30mm, enhancing both appearance and handling.

Designed specifically for the 2014 and newer BMW 4 Series Gran Coupe models, including 435i, 440i, and 430D variants, these springs are a direct replacement for the factory components. They are suitable for street driving and spirited performance applications, offering improved stability and reduced body roll. Installation is straightforward as bolt-on replacements, compatible with the factory suspension setup. The kit includes the pair of lowering springs, ensuring a complete upgrade. These springs are ideal for drivers seeking a lowered stance with enhanced handling characteristics, whether for daily driving or weekend spirited runs.
