AST Suspension Lowering Springs (40mm/40mm) - 1990-1994 BMW 5 Series 525iX Allroad 4WD (E34)

The AST Suspension Lowering Springs for the 1990-1994 BMW 5 Series E34 are high-performance coil springs designed to lower the vehicle's ride height by 40mm. Constructed from high tensile chromium-silicone wire, these springs are carefully handpicked for quality and metal consistency. Each spring undergoes a rigorous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening. The springs are then phosphate treated and powder coated to ensure durability and longevity, surpassing the lifespan of the vehicle. Featuring progressive rates on most applications, these springs improve handling, stability, and aesthetics by reducing body roll and lowering the center of gravity.

Designed specifically for the E34 chassis from 1990 to 1994, these springs are compatible with all-wheel-drive 5 Series models, including the 525iX Allroad 4WD. They serve as a direct replacement for stock springs, offering a performance upgrade suitable for street and spirited driving. Installation is straightforward as bolt-on components, and the kit includes the set of lowering springs. These springs are ideal for enthusiasts seeking improved cornering, a more aggressive stance, and enhanced handling characteristics without compromising ride quality. They are suitable for daily driving, street use, and track days, providing a reliable upgrade for the BMW E34 platform.
