The BC HM Series Coilover Suspension Kit features 30 levels of separate rebound and compression damping force adjustment, full-length height adjustment allowing extremely low ride height, and external reservoirs. The BC HM Series Coilover has been especially designed and developed to meet the demands of the serious driver for professional competition use. Its external reservoirs allow more oil to be contained than a conventional coilover, to slow down oil temperature increase.

About the HM Coilover

BC Racing's HM 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 the weight can be more easily shaved. With the combination of inverted mono-tube dampers and external reservoirs the HM Series is suited for the most demanding users on the track.
