▶ Vehicle Fitments
The AST Lowering Springs for the BMW 5 Series E39 (1995-2003) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are carefully selected by AST engineers for their quality and consistency. The manufacturing process involves cold winding, heat treatment to enhance hardness and reduce internal stresses, followed by shot peening, phosphate treatment, and powder coating to ensure durability and longevity. Featuring progressive rates on most vehicles, these springs provide a balanced ride with improved cornering stability and a lowered stance, enhancing both performance and appearance.
Designed specifically for 1995-2003 BMW 5 Series sedans, these springs are a direct upgrade for the factory suspension. They are suitable for street and performance driving, offering improved handling without sacrificing ride comfort. The installation is a bolt-on process, replacing the original springs to lower the vehicle by approximately 35mm at the front and rear. These springs are compatible with models equipped with Electronic Damping Control (EDC), ensuring proper fitment and function. The kit includes the lowering springs, providing a straightforward upgrade for enthusiasts seeking enhanced driving dynamics and a more aggressive look.
