Choose options
The AST Lowering Springs are engineered to provide a precise lowering solution for BMW 5 Series models 520i, 530i, 518D, and 520D equipped with air suspension at the rear, manufactured between 03/2017 and 02/2024. These springs are cold-coiled using the most advanced Wafios coiling machines, ensuring exceptional quality and durability. Designed specifically for the front axle, they achieve a lowering of 30 mm, effectively reducing the vehicle’s center of gravity without compromising the comfort traditionally offered by OEM springs.
Crafted with precision and high-grade materials, the AST Lowering Springs enhance the vehicle’s handling characteristics by improving stability and cornering performance. Their progressive spring rate design allows for a smooth transition in ride height reduction, maintaining a balance between sportiness and everyday drivability. This makes them ideal for drivers seeking improved dynamics while retaining the refined comfort expected from a premium vehicle.
These springs are a direct replacement for the OEM front springs and are tailored to fit the specified BMW models with air suspension at the rear. The installation does not interfere with the existing air suspension system, ensuring compatibility and preserving the vehicle’s original ride quality. The AST Lowering Springs come with a lifetime warranty against breaking, reflecting the manufacturer’s confidence in their product’s longevity and reliability.
It is important to note that these springs are not suitable for four-wheel-drive (4WD) vehicles and are intended exclusively for Touring models with rear air suspension. Additionally, vehicles equipped with standard lowering or M-sport suspension may experience a reduced lowering effect, approximately 10 mm less for M-sport variants. This ensures that the lowering specifications align with the vehicle’s existing suspension setup, maintaining optimal performance and safety standards.
