The RM Series features an inverted monotube shock absorber, with the oil and gas reservoir at the top and attached to the vehicle body. This configuration reduces unsprung weight, allowing the tire to track the asphalt better and preventing bouncing on broken surfaces. It also keeps the oil away from the heat of the brakes, which, during intense use, travels up through the hub and ends up softening the damping. The 42 mm piston rod adds resistance to lateral loads and maintains stable steering geometry.
Complete kit for all four wheels of the BMW 4 Series F32 RWD (14-19) (3-bolt front top mount). Weighs 24 kg. Manufacturer part number I-61-RM-MA.
The front features an inverted shock absorber with adjustable camber pillowball top mounts, while the rear features rubber top mounts or no top mount, depending on the application. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the conical lower 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, 5.5/9 kg/mm.
Before you buy
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 prevent noise; this is a simple maintenance task that does not require opening or repressurizing the shock absorber. For this reason, BC Racing targets this series at the track and recommends the BR, DS, ER, or ZX series for a daily-driven car.
The front pillowball top mounts are a rigid anchor point without elastic elements, and on some vehicle bodies, they transmit a slight tapping 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 top mounts avoid this effect.
