The RM Series features an inverted monotube shock absorber, with the oil and gas reservoir at the top and fixed to the body. This arrangement lightens the unsprung mass, allowing the tire to better track the asphalt and stop bouncing on rough surfaces. It also keeps the oil away from brake heat, which under intense use travels up through the hub and ends up softening the damping. The 42 mm piston rod adds resistance to lateral loads and keeps steering geometry stable.
Complete kit for all four wheels of the BMW 6 Series E63 RWD (03-10). Weighs 23 kg. Manufacturer part number I-52-RM-MA.
The front features an inverted shock absorber with a camber-adjustable pillowball mount, and the rear uses rubber mounts or no mount, depending on the application. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the tapered bottom locking collar prevents the setting from shifting during use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.
There are 2 stiffness combinations available. The one BC Racing defines as default for this car is 9/6 kg/mm.
Before buying
The shock absorber is a cartridge housed inside a threaded body, with grease between the two parts to prevent metal-on-metal contact. It must be cleaned and replenished periodically to prevent noise; this is simple maintenance that does not require opening or re-pressurizing the shock. For this reason, BC Racing targets this series for track use and recommends BR, DS, ER, or ZX for a daily-driven car.
The front pillowball mounts are a rigid anchor without an elastic element, and in some vehicles, they transmit a slight knocking sound into the cabin. This does not indicate a defect, and BC Racing does not cover it under warranty or accept returns for this reason. Configurations with rubber mounts avoid this effect.
