BC Racing RM Series — Inverted Strength for Serious Track Use
The BC Racing RM Series takes everything that makes the BR Series a great all-rounder and moves it up a notch with an inverted design. By flipping the damper, the RM Series relocates the vital damper fluid away from the heat sources that cause fade and fatigue, so it holds up under the extended stress of a race weekend. The inverted layout also handles high-G loading more effectively and shifts the heaviest parts of the coilover up to the chassis mounting points, reducing unsprung weight. It is a durable, purpose-built setup for drivers tackling a road course, hill climb, or tarmac rally.
Why an Inverted Design Is Stronger
In a conventional coilover, the damper body sits low and close to the brakes and road, where heat builds and fluid thins. The RM Series inverts the damper so the fluid moves away from those heat sources, guarding against overheating and the damper fatigue that follows under sustained hard use. The inverted structure is also more rigid, so it manages the high-G loads of hard cornering and heavy braking with greater durability. For drivers who push their car through long, demanding sessions, that resilience is the point.
Less Unsprung Weight, More Control
An inverted layout moves the heavier portions of the coilover up toward the chassis mounting points, which lowers the unsprung weight at each corner. Less unsprung mass lets the suspension respond faster to changes in the surface, helping the tire stay planted through bumps and transitions. On a road course, hill climb, or tarmac rally stage, that sharper response translates into more grip and more confidence. It is the kind of gain that rewards a driver working near the limit.
