The BC Racing HR Series Coilover system offers the same great benefits of the RM Series with the addition of double damping adjustment. Each HR Coilover system offers inverted monotube dampers with independently adjustable compression and rebound. The inverted damper design moves vital damper fluid away from detrimental heat sources to avoid overheating which can cause damper fade under exteme track use.

The inverted damper also allows for decreased unspring weight by moving the majority of the coilover mass up to the chassis where weight can be more easily shaved. With the BC Racing HR Series Coilover system the external reservoir exits the damper at the top allowing for variable mounting locations under the hood or in the trunk for easy adjustment at the track. The combination of inverted monotube dampers and external reservoirs make the HR Series suitable for the most demanding users on the track. The BC Racing HR Series Coilover comes standard with Swift Springs.
