BC Racing HM Series Coilover System (2002 - 2007 Subaru Impreza WRX - GDA / GDB) - F-02-HM
Hybrid Performance for Track-Focused Subaru WRX Builds
Unlock serious suspension performance for your 2002 - 2007 Subaru Impreza WRX (GDA / GDB) with the BC Racing HM Series Coilover System - a hybrid design that blends the best attributes of the RM and ER Series. The HM Series uses a fully inverted mono-tube damper for superior rigidity and reduced unsprung weight, while incorporating the independent compression and rebound adjustability found in the ER Series. With external reservoirs, steel-braided lines, and Swift Springs included as standard equipment, the HM Series is engineered specifically for high-performance Subaru applications and heavy track use.
