Description
The AST Lowering Springs are engineered to provide a refined balance between enhanced vehicle dynamics and maintained ride comfort. Manufactured using advanced cold-coiling technology on state-of-the-art Wafios machines, these springs ensure consistent quality and durability. Designed specifically for BMW 5 Series models 520i, 523i, 525i, 528i, 530i, and 520D produced between 07/2003 and 03/2010, they offer a precise fit and optimal performance.
By lowering the vehicle’s center of gravity by 50 mm at both the front and rear, these springs contribute to improved handling characteristics, reduced body roll, and a sportier stance without compromising the comfort levels expected from OEM components. The progressive spring design adapts to driving conditions, ensuring a smooth yet responsive ride. Constructed from high-quality materials, the AST Lowering Springs are built to withstand rigorous use and come with a lifetime warranty against breaking, reflecting the brand’s commitment to reliability and customer satisfaction.
Installation is straightforward as these springs serve as direct replacements for the original equipment. Their compatibility with a wide range of vehicles—over 2500 models from 1966 onwards—demonstrates their versatility and engineering precision. However, it is important to note that these springs are not suitable for vehicles equipped with level adjustment systems or four-wheel drive (4WD). Additionally, vehicles fitted with factory sports or M-Sports suspensions will experience approximately 25 mm less lowering.
