BC Racing Coilovers RM Series Coilovers for BMW 5 Series Sedan '95-'03 E39

The BC Racing RM series feature high quality damping adjustable mono-tube inverted dampers at the front or front and rear, depending on vehicle. The RM coilovers offer the majority of the features of the BR series but with the additional benefit of the inverted damper unit. Inverting the damper unit brings with it a number of advantages.
REDUCED HEAT TRANSFER TO THE GAS AND OIL RESERVOIR
Any hard driven car with generate a lot of heat within its braking system. This heat is conducted through the hub to the damper unit. By inverting the oil and gas reservoir the oil and gas is moved away from the hub assembly . This reduces the amount of conducted heat being transferred from the braking system to the hub then to the damper and then on to the gas and oil. As the oil and gas is heated its properties change which has a knock on effect on the damping characteristics of the suspension. By keeping the gas and oil temperatures down BC Racing RM coilovers keep damping rates more consistent resulting in better performing suspension and ultimately allowing you to corner faster, which is the bottom line. REDUCED FLEX
The large 42mm damper rod and inverted design gives the inverted damper units much greater strength and resistance to side loadings. By reducing flex the RM inverted units lead to more consistent steering geometry resulting in more predictable and responsive handling. RM SERIES INVERTED COILOVER
