The AST Lowering Springs are engineered specifically for BMW 3 4CYL models from 1998 to 07/2006, providing a precise fit and optimal performance. Manufactured using advanced Wafios coiling machines, these cold-coiled springs ensure superior quality and durability. Designed to lower the vehicle’s center of gravity—front by 50 mm and rear by 40 mm—they enhance handling and stability without compromising the ride comfort typically expected from OEM springs.

These springs offer a progressive rate design that balances sportiness and comfort, making them suitable for daily driving as well as spirited road use. Their robust construction guarantees long-term reliability, supported by a lifetime warranty against breaking. This commitment to quality reflects AST’s dedication to meeting the highest industry standards and customer satisfaction.

Installation of the AST Lowering Springs is straightforward, as they serve as direct replacements for the original springs. This ensures compatibility and preserves the integrity of the vehicle’s suspension system. By lowering the center of gravity, these springs improve cornering response and reduce body roll, contributing to a more confident and controlled driving experience.
