The inverted shock absorber is what sets the RM Series apart. With the oil and gas reservoir anchored to the body instead of the hub, it reduces unsprung mass: the wheel responds faster to every imperfection and maintains better contact with the road. This same position protects the oil from the heat generated by the brakes, so the damping performance is the same on the last lap as it is on the first. It features a 42 mm shaft, which is more resistant to lateral loads.
Complete kit for all four wheels of the BMW 1 Series E82 1M Coupe (11-12) (wide body 3.0t). Weighs 23 kg. Manufacturer reference I-21-RM-MA.
The front is fitted with an inverted shock absorber with an adjustable camber pillowball top mount, and the rear features rubber top mounts or no top mounts, depending on the application. The front axle allows for camber and caster adjustment, which is not available in all applications. Ride height is adjusted independently of spring preload, and the tapered bottom locking collar prevents the setting from shifting with use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.
Supplied with a single spring rate, 7/12 kg/mm.
Before buying
The shock absorber is a cartridge housed inside a threaded body, and a grease is applied between both parts to prevent metal-to-metal contact. It must be cleaned and replenished periodically to avoid noise; this 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.
The front pillowball top mounts are a rigid anchor, without an elastic element, and in some body styles, 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 top mounts avoid this effect.
