AST Suspension Lowering Springs (40mm/40mm TUV) - 1988-1995 BMW 5 Series 518i/520i (E34)

The AST Suspension Lowering Springs for the 1988-1995 BMW 5 Series (E34) are high-performance coil springs designed to improve handling and aesthetics by lowering the vehicle's ride height by 40mm. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and metal 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. These springs feature progressive rates on most vehicles, providing a balance of comfort and performance, and are engineered to withstand the rigors of daily driving and spirited handling.

Designed specifically for the E34 chassis from 1988 to 1995, these springs are compatible with BMW 518i and 520i models. They serve as a direct replacement for stock springs, offering improved cornering, reduced body roll, and a more aggressive stance. Installation is straightforward for those familiar with suspension upgrades, and the springs are suitable for street use, track days, or performance-oriented driving. The kit includes the set of lowering springs, ensuring a complete upgrade for enthusiasts seeking enhanced handling and a lowered profile without compromising ride quality.
