BC Racing HM Series Coilovers deliver precision suspension tuning for the Subaru WRX/STI VAB/VAF/VAG (14+), engineered with a 7/6kg.mm spring rate to enhance handling dynamics and cornering performance. These premium coilovers combine advanced damping technology with adjustable ride height, offering drivers the control needed for both road and track applications. Built to demanding quality standards, BC Racing HM Series coilovers are the choice for Subaru enthusiasts seeking reliable, high-performance suspension upgrades.
BC Racing HM Series Coilovers
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 system features inverted monotube dampers with independently adjustable compression and rebound. The inverted damper design moves vital damper fluid away from detrimental heat sources to avoid overheating and damper fade under extreme track use, while also decreasing unsprung weight by moving the majority of the coilover mass up to the chassis — improving ride quality, wheel control and steering feel. With the combination of inverted monotube dampers and external reservoirs, the HM Series is suited to the most demanding users on track.

Inverted Monotube with External Reservoir
The inverted design positions the damper body at the top of the assembly, reducing unsprung weight and moving damper fluid away from brake-generated heat at the wheel end. The external reservoir adds further oil capacity via Teflon-coated steel braided lines — combining both advantages for effective thermal management in demanding track conditions.
