Product Details
The BC Racing HM Series Coilover System gets 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. Each HM Series Coilover System uses inverted mono-tube dampers front and rear on McPherson strut vehicles with steel braided lines leading from the top of the damper to the external reservoirs. The external reservoirs allow for a higher oil capacity with the added benefit of increased thermal dissipation, they also house the secondary damping piston. For Subarus and other McPherson suspension vehicles that are heavily tracked, the BC Racing HM Series Suspension System is definitely worth checking out!
Adjustment that stays usable
Ride height is set independently of spring compression, so lowering the car does not preload the spring or cost you travel. Damping is a single 30-click sweep moving compression and rebound together — one adjustment per corner, easy to repeat and easy to undo.
Built to be serviced, not replaced
Every kit is fully rebuildable and can be revalved, and custom spring rates — including Swift Springs — are available if your setup outgrows the off-the-shelf specification.
