Description
The AST Lowering Springs are engineered to provide a refined balance between enhanced vehicle dynamics and ride comfort, specifically designed for BMW 5 Series models 520/523/528/530/518D/520D equipped with air suspension on the rear axle, covering production years 06/2010 to 03/2017. Manufactured using advanced Wafios coiling technology, these cold-coiled springs ensure superior durability and consistent performance, meeting the highest industry standards.
These springs offer a direct replacement for the original equipment manufacturer (OEM) springs, allowing for a significant lowering of the vehicle’s center of gravity without compromising the comfort levels expected from OEM components. The progressive spring design optimizes handling and stability, contributing to improved cornering and overall driving dynamics, while maintaining a smooth and controlled ride quality.
Included in the set are lowering links for the rear suspension, which provide adjustable lowering options ranging from 0 to 30 mm. The front lowering is fixed at 30 mm, ensuring a balanced stance and precise suspension geometry. This adjustability allows for fine-tuning the ride height to suit individual preferences or specific driving conditions, enhancing both aesthetics and performance.
AST’s commitment to quality is underscored by a lifetime warranty against spring breakage, reflecting confidence in the materials and manufacturing processes. The springs are suitable for a wide range of applications, with compatibility across numerous BMW 5 Series variants, ensuring a tailored fit and reliable function.
Notes:
- Not suitable for 4WD (four-wheel drive) vehicles.
- For vehicles with standard lowering, the effective lowering will be reduced by the amount of the standard lowering already present.
- The rear suspension includes adjustable lowering links.
- Adjusting the lowering link by 1 mm changes the vehicle height by approximately 5 mm.
- Minimum rear ride height is approximately 355 mm, measured from the center of the wheel to the wheel arch; exceeding this lowering may adversely affect ride quality.
- Lowering the ride height reduces the air volume in the suspension system; excessive lowering may cause errors in the vehicle’s computer system.
