HM Series: Track-use ‐ 2-way adjustable – inverted dampers (Stage 4.1)
The BC Racing HM Series Coilover system offers the same great benefits of the RM Series with the addition of 2-way damping adjustment. Each HM Coilover system offers inverted mono-tube 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 extreme track use. The inverted damper also allows for decreased unsprung weight by moving the majority of the coilover mass up to the chassis where weight can be shaved more easily. With the BC Racing HM Series Coilover System, the external reservoir exits the damper at the top allowing for infinitely variable mounting locations under the hood or in the trunk for easy adjustment at the track. The combination of inverted mono-tube dampers and external reservoirs make the HR Series suited for the most demanding users on the track.
