BC racing’s HM series for the BMW E90 3-Series RWD uses an inverted mono-tube damper front and rear on McPherson strut vehicles with steel braided lines leading from the top of the damper to the external reservoirs, just like the RM Series, but adds the independent compression and rebound adjustment of the ER Series.

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 worth checking out!

BC Racing has earned a reputation for its high-quality coil overs that provides superior performance. Whether you want a high or low set-up, it still offers a superior driving experience. The lower you go, the more gains in the center of gravity.
