BC Racing ZR Series Coilover System (2002 - 2007 Subaru Impreza WRX - GDA / GDB) - F-02-ZR
Ultimate Multi-Adjustable Coilovers for the 2002 - 2007 WRX
For WRX owners who demand the highest level of suspension control, the BC Racing ZR Series Coilover System delivers unmatched adjustability and track-focused performance. Purpose-built for the 2002 - 2007 Subaru Impreza WRX (GDA / GDB), the ZR Series is engineered for racers who need more tuning capability than the ER or HM Series can provide. Featuring high- and low-speed compression adjustments, 30-way rebound control, and fully independent ride height adjustment, the ZR Series offers professional-grade tuning for competitive environments. For McPherson-strut Subarus like the WRX, BC equips the kit with inverted mono-tube dampers and externally mounted reservoirs to ensure heat stability and precise damping consistency under extreme use.
