AST Lowering Springs For BMW 3 6CYL.+ 320D 1998-07/2006, Front 40 , Rear 30

The AST Lowering Springs are engineered to enhance your BMW 3 6CYL.+ 320D (1998-07/2006) driving experience by lowering the vehicle’s center of gravity while maintaining a high level of ride comfort. Manufactured with precision on advanced Wafios coiling machines, these springs provide a reliable and durable solution for improving handling and stability without compromising the quality you expect from OEM components.

Designed specifically for the front and rear suspension—offering a 40 mm drop at the front and 30 mm at the rear—these springs optimize your vehicle’s stance and performance characteristics. The progressive coil design ensures smooth transition and consistent response during dynamic driving conditions, resulting in improved cornering and reduced body roll. Their robust construction guarantees longevity and resistance to fatigue under normal operating conditions.

AST’s commitment to quality is reflected in the lifetime warranty against breaking, providing assurance and confidence in your investment. These lowering springs are a direct replacement for the OEM springs, ensuring straightforward installation and compatibility with your vehicle’s suspension system. Whether for daily driving or spirited performance, these springs offer an ideal balance between sportiness and comfort.
