Inverting the shock absorber is what sets the RM Series apart. With the oil and gas reservoir anchored to the body instead of the hub, unsprung mass is reduced: the wheel responds faster to every irregularity and maintains better contact with the ground. That same position protects the oil from the heat generated by the brakes, ensuring the damping performance is the same on the last lap as it is on the first. It features a 42 mm piston rod, which is more resistant to lateral loads.
Complete kit for all four wheels of the BMW 5 Series E60 xDrive (03-10). Weighs 24 kg. Manufacturer part number I-86-RM-MA.
The front features an inverted shock absorber with a camber-adjustable pillowball mount, and the rear includes rubber mounts or no mounts, depending on the application. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the tapered lower locking collar prevents the setting from shifting during use. Includes dust boots to protect the seals and a 1-year warranty against manufacturing defects.
Supplied with a single spring rate: 6.5/4.5 kg/mm.
Before you buy
The shock absorber is a cartridge housed inside a threaded body, with grease applied between the two parts to prevent metal-to-metal contact. This must be cleaned and reapplied periodically to avoid noise; it is simple maintenance that does not require opening or repressurizing the shock absorber. For this reason, BC Racing targets this series for track use and recommends BR, DS, ER, or ZX for a daily-driven car.
Front pillowball mounts are a rigid attachment, without elastic elements, and on some chassis, they may transmit a slight knocking sound into the cabin. This does not indicate a defect, and BC Racing does not cover it under warranty nor accept returns for this reason. Configurations with rubber mounts avoid this effect.
For vehicles with a 50 mm front shock absorber. Please check the measurement before ordering.
