AST Lowering Springs For BMW 4 420i/430i 11/2020-, Front 30 , Rear 25
Description
The AST Lowering Springs are engineered to enhance your BMW 4 Series 420i/430i (from 11/2020 onwards) by effectively lowering the vehicle’s center of gravity while maintaining a high level of comfort comparable to the original equipment manufacturer (OEM) springs. Manufactured using premium materials and precision cold-coiling technology on advanced Wafios coiling machines, these springs ensure durability and consistent performance. Their progressive design allows for a refined balance between improved handling dynamics and ride quality, making them an excellent choice for drivers seeking both aesthetics and functionality.
Designed specifically for each vehicle model, the AST Lowering Springs offer a direct replacement for OEM springs, guaranteeing a seamless fit and optimized performance. With over 2500 vehicle applications from 1966 to present day, AST’s extensive expertise is reflected in these springs’ adaptability and reliability. Additionally, the product comes with a lifetime warranty against breaking, underscoring the brand’s commitment to quality and customer satisfaction.
Installation of these springs results in a front lowering of 30 mm and a rear lowering of 25 mm, effectively reducing body roll and enhancing cornering stability without compromising everyday driving comfort. This makes the AST Lowering Springs an ideal upgrade for those who want to improve their vehicle’s stance and handling characteristics while preserving the smooth ride expected from BMW’s engineering standards.
