Description
The AST Lowering Springs for BMW 4 Series models 435i, 440i, and 430D (manufactured between 03/2014 and 07/2021) represent a meticulously engineered solution designed to enhance your vehicle’s driving dynamics by lowering its center of gravity. Manufactured with precision on advanced Wafios coiling machines, these springs are cold-coiled to ensure optimal strength and durability. The set includes front and rear springs, each providing a 40 mm lowering effect, striking a balance between improved handling and retained ride comfort.
These lowering springs are developed as a direct replacement for the original equipment manufacturer (OEM) springs, tailored specifically for the BMW 4 Series to maintain the vehicle’s intended suspension geometry and performance characteristics. Their progressive spring rate design allows for enhanced cornering stability and reduced body roll while preserving the smoothness and comfort expected from OEM components. This makes them an ideal choice for drivers seeking a sportier stance and improved road feel without compromising everyday usability.
Crafted from high-quality 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 customer satisfaction. Suitable for a wide range of vehicles, these springs have been successfully applied to over 2500 models since 1966, demonstrating their versatility and proven performance in the automotive aftermarket.
Please note that these springs are not compatible with four-wheel drive (4WD) vehicles. Additionally, vehicles equipped with M-sport or Adaptive M-sport suspension systems will experience approximately 10 mm less lowering effect compared to standard models.
