BC Racing RM Series Coilovers

Inverted Suspension for Track Day Use

BC Racing RM Series Features

Mono-tube inverted dampers:

Reduced Damper Flex

The BC Racing RM Coilovers use large 42mm inverted monotube dampers. This inverted style allows both the inner and outer tubes to take all of the side loads encountered when cornering. This reduced flex of the BC Racing RM series gives a more predictable steering feel and improved responsive handling. It also improves the life of the BC Racing damper seals.

The mono-tube inverted damper design on the BC Racing RM series coilovers has a number of advantages, including reducing unsprung weight by moving the oil and gas reservoir way from the hub and attaching it to the shell.

Reduced heat transfer

Also by inverting the coilover damper the oil and gas is moved away from the hub assembly. This means that less heat is transferred to the oil under braking which makes for more consistent damping.

Combined Rebound and Compression Adjustment

These BC Racing RM series coilovers feature 30 clicks of damping adjustment combining both rebound and compression in one adjuster for simplicity and ease of use.

Standard Features of all BC Racing Coilovers

Ride Height Adjustment

BC Racing Coilovers alter ride height using an adjustable bottom mount. As ride height is set by this bottom mount rather than the spring platform your BC Racing Coilover retains full damper travel no matter what your ride height. This also allows the BC Racing Coilover spring pre-load to be set independently.

Nitrogen pressurised Monotube Coilovers

The BC Racing coilover kits use Nitrogen pressurised Monotube dampers with a large diameter pistons and bodies. Mono-tube pistons are much larger than twin-tube coilover dampers. This allows it to be more sensitive to small suspension movements . The larger outer shafts are stronger so they cope with higher side loads. Nitrogen pressurised Monotube coilover dampers give a more consistent damping performance and do not suffer from aeration or performance fade in comparison to a twin tube 

Corner weight adjustment

The lower spring platforms of the BC Racing coilovers are adjustable. This allows the car to be set up for corner weighting to achieve perfect balance and ensures that maximum tyre efficiency is achieved.

The car needs to be placing equal weight on each tyre on an axle so both front tyres need to be taking equal loading as do both rears. This makes sure that both tyres are doing their equal share of work when cornering which increases overall grip, maximises corner speed and reduces lap times.

Top mounts included on most kits

Many of the BC Racing coilover kits come with complete with replacement top mounts. These BC Racing top mounts are either rose jointed (pillowball) top mounts or rubber top mounts. The anodised alloy top mounts eliminate any flex or play associated with the standard rubber top mounts, improving response and handling. In addition some of the BC Racing coilover kits also allow for camber / castor adjustment through the solid top mounts to give additional tuning flexibility.
