The AST 30mm/25mm Lowering Springs for the BMW 6 Series E63/E64 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 strength and metal consistency by AST engineers. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The phosphate coating and powder coating finish ensure durability and resistance to corrosion, allowing these springs to outlast the vehicle itself. Featuring progressive rates on most applications, they provide a balanced ride quality while lowering the vehicle's stance for a sportier appearance and improved cornering performance.

Designed specifically for 2004-2011 BMW 6 Series models (E63/E64), these springs are a direct replacement upgrade for factory components. They are suitable for street and performance driving, offering enhanced handling and a lowered profile that reduces body roll and improves aerodynamics. Installation is straightforward as they are bolt-on components compatible with the original suspension setup. The kit includes the set of springs necessary for the front and rear suspension, ensuring a comprehensive upgrade. These springs are ideal for enthusiasts seeking a lowered, aggressive look combined with improved driving dynamics on both daily and spirited driving scenarios.
