The HM Series coilover system offers the same great benefits as the RM Series, with the addition of the 2-way damping adjustment of the ER Series. Inverted mono-tube dampers* with independently adjustable compression and rebound move vital damper fluid away from detrimental heat sources. This is 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 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 HM Series suited for the most demanding users on the track. |
*The inverted mono-tube dampers are used in the front and rear of vehicles that use McPherson style OEM strut suspension. On vehicles that use McPherson front struts only, inverted front struts are provided and upright BR Series shocks are provided for the rear.
**Please note that not all vehicles use camber plates in the front and/or rear.
