Product Description

The H&R 50404-55 OE Sport Lowering Springs are precision-engineered springs designed for **1985-1991 BMW E30** models including the 325e, 325i, 325is, and the classic E30 M3. These OE Sport springs deliver a subtle lowering of around **1.0 inch front and rear**, reducing the center of gravity to improve cornering, reduce body roll, and enhance overall handling dynamics while maintaining comfortable daily ride quality. Their progressive spring design strikes a balance between performance and comfort, offering a more controlled driving feel and a slightly more aggressive stance without the harsher ride of more aggressive lowering springs.

Constructed in Germany from high-strength 54SiCr6 spring steel and shot-peened for durability, the 50404-55 springs are a direct bolt-in replacement for the factory springs - no cutting or special modifications are required. After installation, a professional alignment is recommended to optimize suspension geometry and tire wear. These springs are an excellent choice for E30 enthusiasts who want a refined balance of improved handling, a modest drop, and everyday ride comfort.
