Description

BC Racing HM Series Coilovers for the 2001-2006 BMW M3 (E46) get 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. The external reservoirs house the secondary damping piston, and allow for a higher oil capacity with the added benefit of increased thermal dissipation.

For vehicles with front and rear McPherson struts, the HM Series comes standard with an inverted mono-tube damper. The damper has a steel braided line exiting the top of the damper leading to the external reservoirs that can be remotely mounted on the chassis for easy adjustment.

Vehicles with a Double A-Arm suspension come with upright dampers. These dampers have steel braided lines or solid stems that exit the damper at the bottom and lead to the external reservoir that can be mounted under the chassis or on the shock body itself.

Not all vehicles allow for inverted front and rear dampers. In such cases, an upright mono-tube damper will be supplied. The braided line/hard stem for the external reservoir exits the base of the damper when not inverted.

For Subaru's and other McPherson suspension vehicles that are heavily tracked, the BC Racing HM Series Coilover System is definitely worth checking out!
