Description
The AST Lowering Springs are engineered to provide a refined balance between enhanced vehicle dynamics and ride comfort. Manufactured through a precision cold-coiling process on state-of-the-art Wafios machines, these springs are designed specifically for BMW 5 Series models 520/523/528/530/518D/520D equipped with air suspension on the rear axle, covering production years from 06/2010 to 03/2017. The set includes front springs with a fixed lowering of 40 mm and adjustable rear springs ranging from 0 to 40 mm, complemented by lowering links for the rear suspension to facilitate precise ride height adjustment.
AST’s lowering springs offer a direct replacement for the original equipment manufacturer (OEM) springs, crafted to reduce the vehicle’s center of gravity without compromising the comfort levels expected from OEM components. This is achieved through a progressive spring design that ensures a smoother transition in suspension travel, thereby maintaining driving comfort while improving handling characteristics and vehicle stability.
The springs are constructed from premium-grade materials, ensuring durability and long-term reliability. The cold-coiling technique employed guarantees consistent spring rates and structural integrity, which is further supported by a lifetime warranty against spring breakage. This warranty underscores the manufacturer’s commitment to quality and customer confidence.
Installation of these lowering springs results in a sportier stance and improved road feedback, which enhances the overall driving experience. The adjustable rear lowering links allow fine-tuning of the vehicle’s rear height, with 1 mm of adjustment on the link corresponding to approximately 5 mm change in ride height. This flexibility enables customization according to driver preference and load conditions.
Notes
- Not suitable for 4WD (four-wheel drive) vehicles.
- For vehicles with standard factory lowering, the effective lowering will be reduced by the amount of the existing lowering.
- The rear suspension setup includes adjustable lowering links to facilitate height customization.
- Minimum achievable ride height at the rear is approximately 355 mm, measured from the center of the wheel to the wheel arch; exceeding this lowering may adversely affect ride quality.
- Excessive lowering reduces air volume in the suspension system, which may trigger error codes within the vehicle’s onboard computer.
