The AST Lowering Springs are engineered to provide a precise lowering solution for BMW 5 Series models 520i, 523i, 525i, 528i, 530i, and 520D manufactured between 06/2004 and 05/2010. Designed with advanced cold-coiling technology on premium Wafios coiling machines, these springs ensure exceptional quality and durability, meeting rigorous automotive standards.
These springs effectively lower the vehicle’s center of gravity by 30mm at the front, enhancing handling dynamics and stability without significantly compromising ride comfort. The progressive coil design balances performance and comfort, maintaining the familiar driving experience associated with original equipment manufacturer (OEM) springs. This makes them an ideal choice for drivers seeking improved road contact and reduced body roll during cornering.
Manufactured specifically for each vehicle model, AST Lowering Springs are a direct replacement for OEM springs, ensuring seamless installation and compatibility. Their construction from high-quality materials guarantees long-lasting performance, supported by a lifetime warranty against breaking. This warranty underscores the brand’s commitment to reliability and customer satisfaction.
The set is designed exclusively for front suspension lowering, with the rear springs remaining at standard height. It is important to note that these springs are suitable only for Touring models equipped with air suspension at the rear. They are not compatible with four-wheel drive (4WD) vehicles. Additionally, vehicles fitted with factory sports or M-Sports suspension will experience approximately 25mm less lowering.
