The AST Lowering Springs are meticulously engineered to provide a significant reduction in your BMW’s center of gravity, enhancing handling and stability without compromising the ride comfort associated with original equipment manufacturer (OEM) springs. Manufactured using advanced Wafios coiling machines, these springs are cold-coiled to ensure exceptional durability and precision. The design philosophy behind these springs focuses on delivering a progressive lowering effect that improves vehicle dynamics while maintaining a smooth and controlled ride.
Specifically developed for BMW models produced between 06/1981 and 12/1987, including 518, 520, i, SE, 524, D, TD, 525i, 528i, and 535i variants, these springs offer a front lowering of 45 mm and a rear lowering of 35 mm. This targeted drop in ride height not only improves the aesthetic stance of your vehicle but also contributes to enhanced cornering performance and reduced body roll, essential for both everyday driving and spirited performance conditions.
Crafted from premium materials and subjected to rigorous quality control, the AST Lowering Springs come with a lifetime warranty against breaking, underscoring the brand’s commitment to reliability and long-term performance. Their compatibility with a wide range of vehicles—over 2500 models spanning from 1966 to present—demonstrates the versatility and adaptability of these springs. Please note, however, that these springs are not suitable for vehicles equipped with level adjustment systems, automatic or electronic shock absorption regulation, M-models, S4 models, or Audi sport chassis.
