Description
The AST Lowering Springs are engineered to provide a precise lowering solution for BMW 4 Series models 420i, 428i, 430i, 418D, 420D, and 425D manufactured between 07/2013 and 10/2020. Designed with meticulous attention to detail, these springs lower the vehicle by 30 mm at both the front and rear, effectively reducing the center of gravity to enhance handling and driving dynamics without compromising ride comfort.
Manufactured using advanced cold-coiling technology on state-of-the-art Wafios coiling machines, the AST springs demonstrate exceptional precision and durability. The progressive spring design ensures a balanced reduction in ride height while maintaining the suspension’s ability to absorb road irregularities, preserving the driving comfort expected from original equipment manufacturer (OEM) components.
Each set is tailored specifically for the vehicle model, guaranteeing compatibility and optimal performance. The use of premium materials and rigorous manufacturing standards underpin the reliability of these springs, which are supported by a lifetime warranty against breaking, reflecting the brand’s confidence in product quality and longevity.
The installation of AST Lowering Springs not only improves the aesthetic appeal by achieving a sportier stance but also contributes to enhanced vehicle stability during cornering and braking. This makes them an ideal upgrade for drivers seeking to improve their BMW’s performance characteristics while retaining everyday usability.
