The AST Lowering Springs are engineered to provide a precise and reliable solution for lowering the center of gravity of your BMW 5 Series (models 520i, 523i, 525i, 528i, 530i, 520D) manufactured between 06/2004 and 05/2010. These springs are cold-coiled using the highest quality Wafios coiling machines, ensuring superior manufacturing standards and consistent performance. Designed specifically for front suspension lowering by 50 mm, with rear springs included, they maintain a commendable balance between enhanced driving dynamics and ride comfort.
Crafted from premium materials, the AST Lowering Springs serve as a direct replacement for the original equipment manufacturer (OEM) springs. Their progressive coil design optimizes vehicle handling by reducing body roll and improving cornering stability without compromising the comfort levels typically expected from OEM components. This makes them an ideal choice for drivers seeking improved performance while retaining everyday usability.
The extensive application range of AST springs, covering over 2500 vehicle models since 1966, attests to their adaptability and engineering excellence. Additionally, these springs come with a lifetime warranty against breaking, underscoring the brand’s commitment to quality and reliability. This warranty provides assurance for long-term use under normal driving conditions, reflecting the product’s durability and robust construction.
