AST Lowering Springs For BMW 5 520/523/528/530/518D/520D 03/2010-01/2017, Front 40 , Rear 35

The AST Lowering Springs are precision-engineered components designed specifically for BMW 5 Series models 520, 523, 528, 530, 518D, and 520D produced between 03/2010 and 01/2017. Manufactured using advanced cold-coiling technology on state-of-the-art Wafios coiling machines, these springs provide a reliable and high-quality solution to enhance vehicle dynamics by lowering the center of gravity while maintaining a high level of ride comfort comparable to OEM springs.

These springs feature a progressive design that optimally balances performance and comfort, ensuring improved handling and stability without compromising the everyday driving experience. The front springs lower the vehicle by 40 mm, while the rear springs provide a 35 mm reduction, achieving a sportier stance and enhanced road grip. Crafted from premium materials, AST Lowering Springs are built to last and come with a lifetime warranty against breakage, reflecting the brand’s commitment to durability and customer satisfaction.

Ideal for drivers seeking to improve their BMW’s aesthetics and driving dynamics, these springs serve as a direct replacement for the OEM springs and are tailored to the specific requirements of the designated vehicle models. Their compatibility and precise engineering ensure seamless installation without the need for additional modifications. It is important to note that these springs are not suitable for four-wheel-drive (4WD) vehicles and that the effective lowering height may be reduced if the vehicle already has standard lowering modifications.
