BC Racing ER Series coilovers

BC Racing ER Series Coilovers

External Reservoir for Ultimate Street Performance & Track Orientated Vehicles

BC Racing's ER Series coilover set has separate adjustment of the damping compression and rebound. As well as featuring large monotube dampers, The ER Series has large external reservoirs front and rear allowing much more oil to be contained compared to conventional coilovers. This allows the coilover to operate for much longer and be worked harder before overheating making them ideal for rougher surface roads and tracks. The external reservoirs house the secondary piston for adjusting the compression. Rebound adjustment is done on the main damper body. The ER Series coilover is the perfect system for the driver who wants to dial in their suspension by varying the compression and rebound settings to fit a specific driving style and performance demand.

  • Mono-tube damper with twin piston design
  • height adjustment via shock body - not spring
  • 30 clicks of independently adjustable compression and rebound
  • front and rear camber plates are standard on all applicable kits
  • front and rear pillowball top mounts standard where camber plates do not apply
  • custom valved to match the drivers requested spring rates
  • 1 year limited warranty against manufacturer defects
  • fully rebuildable with all parts available for purchase

BC Racing ER Series Features

46mm diameter pistons / 53mm diameter damper body

The BC Racing ER series coilovers use a larger 46mm diameter piston in a 53mm diameter damper body to maximise the oil capacity. The larger outer shafts give additional strength enabling them to cope with higher side loads.

External Reservoirs

These BC Racing ER series coilovers The external reservoirs hold much more oil than conventional coilovers, allowing the unit to operate for much longer before overheating.

2-way adjustable Damping - Separate Rebound and Compression Adjustment

the external reservoirs also house a secondary piston, which allows for separate adjustment of rebound and compression damping. Rebound damping is adjusted on the top of shock and compression damping is adjusted on the external reservoir

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 BC Racing Suspensiondamper design.

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.

Corrosion protection

The BC Racing Coilover damper units are black chromed steel to give superb durability against the weather and road salt in winter.
The aluminium components are anodised and the steel lower mounts go through an electrocoating process followed by powder coating.

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.

Optional BC Racing Damping Extenders

The BC Racing coilover kits are available to be purchased with rear damping extender cables. If chosen these allow you to adjust the 30 way damping from a more convenient position on the car. Three lengths are available and these can be cut down to size.
