The AST Lowering Springs are engineered to enhance the driving dynamics of your BMW 5 series (models 518i, 520i, 525i, 525TD, 525TDS) manufactured between 01/1988 and 03/1997. Designed as a direct replacement for the OEM springs, these springs provide a precise lowering of 35 mm at both the front and rear, effectively reducing the vehicle’s center of gravity. This reduction contributes to improved handling stability and cornering performance without significantly compromising ride comfort.
Manufactured using advanced cold-coiling technology on state-of-the-art Wafios machines, the AST springs guarantee superior material consistency and durability. The progressive spring design ensures a balanced distribution of stiffness, allowing for enhanced road contact and vehicle control while maintaining a comfortable driving experience comparable to the original equipment. These springs are rigorously tested and come with a lifetime warranty against breaking, underscoring AST’s commitment to quality and reliability.
Installation of these lowering springs is straightforward, as they are tailored specifically for the listed BMW 5 series models, ensuring compatibility and optimal fitment. It is important to note that these springs are not suitable for vehicles equipped with automatic or electronic shock absorbing regulation systems, nor for M-models, S4 models, or cars fitted with Audi sport chassis. Additionally, due to the inherent differences in standard ride height between front and rear suspensions, the actual lowering effect post-installation may vary slightly from the catalog specifications.
