Product Description

The H&R 50490 Sport Lowering Springs are engineered specifically for **BMW 3-Series E90 sedan models** - including **325i, 328i, and 330i** with rear-wheel drive and the N52 3.0 L engine. These sport springs lower the vehicle by approximately **1.3 inches at the front** and **1.2 inches at the rear**, bringing the center of gravity closer to the pavement for improved handling dynamics, reduced body roll through corners, and a sharper steering response. The lowered stance also gives the car a more aggressive look with reduced wheel-to-fender gap.

Built from high-strength 54SiCr6 spring steel with a progressive rate design and protective coating, the 50490 springs balance enhanced performance with a comfortable ride suitable for daily use. Installation is a direct bolt-in replacement for the factory springs and does not require cutting or special modification. A professional alignment after installation is recommended to optimize suspension geometry and tire wear for the best overall driving experience. These springs are a popular upgrade for E90 owners seeking improved handling and visual stance without sacrificing everyday drivability.
