Product Description

The H&R 50490-88 Race Lowering Spring Kit is engineered for BMW 3-Series E90 sedan (2007-2011) and E92/E93 coupe & convertible (2007-2013) models equipped with the 3.0 L inline-6 (N52, N54, or N55 engines). Delivering approximately 2.0" of front and 1.5" of rear lowering (with sport suspension variations noted), this kit enhances handling by reducing center-of-gravity while maintaining ride comfort for aggressive street and track use.

Constructed from high-strength 54SiCr6 spring steel and certified via ISO-9001 quality processes, these springs are shot-peened and block-set for longevity and drift stability. The four-spring set is durable, powder-coated for weather resistance, and designed to improve responsiveness, reduce body roll, and support performance driving. Use of camber adjustment hardware is recommended to correct negative camber after installation.
