Description
The AST Lowering Springs are precision-engineered to enhance your BMW 4 Series driving experience by lowering the vehicle’s center of gravity while maintaining a high level of comfort comparable to the original equipment manufacturer (OEM) springs. Manufactured using state-of-the-art Wafios coiling machines, these springs are cold-coiled to ensure optimal durability and performance. Their progressive design allows for a balanced reduction in ride height, improving handling and stability without compromising ride quality.
Specifically developed for BMW 4 Series models 420i, 428i, 430i, 420D, and 425D produced between 03/2014 and 07/2021, this set includes front and rear springs that lower the vehicle by approximately 30 mm each. This targeted lowering contributes to a more dynamic stance and enhanced road grip, which is especially beneficial during cornering and high-speed maneuvers. The springs are made from premium materials and undergo rigorous quality control to meet stringent automotive standards.
AST’s commitment to quality is further demonstrated by the lifetime warranty against breaking, providing assurance of long-term reliability and performance. These springs are a direct replacement for the OEM components, ensuring straightforward installation and compatibility with your vehicle’s existing suspension system. With over 2500 vehicle applications from 1966 to the present day, AST Lowering Springs represent a trusted solution for drivers seeking to enhance their vehicle’s dynamics without sacrificing comfort.
