The AST Lowering Springs are expertly engineered to enhance your BMW 5 Series driving experience by lowering the vehicle’s center of gravity without compromising the comfort and handling characteristics you expect from OEM springs. Manufactured using advanced cold-coiling technology on the renowned Wafios coiling machines, these springs ensure superior precision and durability for long-lasting performance.
