Product Description

The H&R 50404-88 Race Lowering Springs are engineered for **BMW E30** 3 Series - including 318i, 318is, 325e, 325es, 325i, 325is, and M3 - delivering a **more aggressive drop** and performance focus compared to standard or sport springs. These race-tuned springs drop the ride height by approximately **1.8 inches front and rear**, lowering the center of gravity to sharpen steering response, enhance cornering precision, and reduce body roll during spirited driving. The result is a more connected feel with improved balance between front and rear suspension control.

Built from high-strength spring steel with a progressive rate and fatigue-resistant processes, the 50404-88 springs are ideal for drivers who want **track performance and sharper handling** from their E30's suspension while still retaining usability for street driving. Installation is a direct bolt-in replacement for factory springs - no cutting or special modifications required. After installation, a professional alignment is recommended to optimize suspension geometry, tire wear, and overall vehicle dynamics. These race springs are an excellent upgrade for enthusiasts seeking **enhanced dynamics and a more aggressive stance** over traditional lowering options.
