AST Lowering Springs For BMW 5 520/523/528/530/518D/520D with airsuspension HA 06/2010-03/2017, Front 40 , Rear

The AST Lowering Springs are engineered to provide a precise and reliable solution for lowering the center of gravity of your BMW 5 Series models 520, 523, 528, 530, 518D, and 520D equipped with air suspension (HA) from 06/2010 to 03/2017. Manufactured with meticulous attention to detail, these springs are cold-coiled using the advanced Wafios coiling machines, ensuring consistent quality and durability that meets rigorous automotive standards.

Designed to replace the original equipment manufacturer (OEM) springs directly, the AST Lowering Springs maintain much of the comfort expected from OEM components while significantly improving handling dynamics by lowering the vehicle’s stance. This balance is achieved through a progressive spring design that enhances stability and driving precision without compromising ride quality.

These springs have been developed specifically for each vehicle application, ensuring optimal fitment and performance. The premium materials used in their construction contribute to their longevity and resistance to fatigue, making them a dependable upgrade for your suspension system. Additionally, the product is supported by a lifetime warranty against breaking, reflecting the manufacturer’s confidence in its structural integrity and providing assurance to the end user.

It is important to note that these lowering springs are not suitable for four-wheel drive (4WD) vehicles. For models equipped with a level regulation system, the rear ride height can be adjusted to lower by approximately 15mm through the system’s settings, allowing for further customization of the vehicle’s stance. In cases where the vehicle already features a standard lowering, the effective lowering achieved by these springs will be reduced accordingly.
