The AST Lowering Springs for BMW 4 418i (03/2014-07/2021) represent a meticulously engineered solution designed to enhance vehicle dynamics by lowering the center of gravity while maintaining the ride comfort expected from OEM springs. Manufactured using advanced Wafios coiling machines, these springs are cold-coiled to ensure superior structural integrity and consistent performance over time.
Specifically developed for this BMW model, the AST springs provide a precise fit that guarantees ease of installation as a direct replacement for the original equipment. Their progressive design optimizes suspension behavior, improving handling responsiveness and stability without compromising daily driving comfort. The use of premium materials and cutting-edge manufacturing techniques underscores the brand’s commitment to quality and reliability.
These lowering springs reduce the ride height by 40 mm at both the front and rear, effectively lowering the vehicle’s center of gravity. This adjustment enhances cornering performance and reduces body roll, contributing to a more engaging and controlled driving experience. Despite the reduction in height, the springs are engineered to preserve the smoothness and comfort characteristic of the OEM suspension setup.
AST supports its product with a lifetime warranty against breaking, reflecting confidence in the durability and longevity of their springs. This assurance provides added value and peace of mind for customers seeking a dependable upgrade for their BMW 4 Series.
