The BC Racing HM Series Coilover System gets its great qualities from a combination of two previous BC Racing Coilover Systems - the RM Series and ER Series. The HM Series uses an inverted mono-tube damper, just like the RM Series, but adds the independent compression and rebound adjustment of the ER Series. Each HM Series Coilover System uses inverted mono-tube dampers front and rear on McPherson strut vehicles with steel braided lines leading from the top of the damper to the external reservoirs.
External Reservoir
The external reservoirs allow for a higher oil capacity with the added benefit of increased thermal dissipation, they also house the secondary damping piston. For vehicles that are heavily tracked, the BC Racing HM Series Suspension System is definitely worth checking out!
