BC Racing coilovers design to fit Honda Civic EK/EM/EJ9/MB6 (96-00) - Rear fork

Available in BR (Street and Circuit), DS (Digressive Valving) , ER (External Reservoir) and ZR (3-way Adjustable) series versions.

BR Series Features

• Pillowball upper mount
• Camber adjustable top mounts
• Aluminium top plates
• 30 way adjustable damping
• Adjustable spring platform
• Height adjustment via bottom mount to retain full damper travel
• Bearing mounted upper front spring platform
• Dust boot to protect damper seals

The BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity. As the damper unit operates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.

BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their BR range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.

The lower spring platform 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.

BR coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.

By tweaking front and rear damping you can adjust the way the car handles. Increasing damping force on the rear relative to the front, for example, will start moving the vehicle into a more oversteer orientated stance.

ER Series Features

• External Reservoir
• Individually adjust and set compression and rebound damping rates
• Inverted monotube damper bodies
• Pillowball upper mount
• Camber adjustable top mounts
• Aluminium top plates
• 30 way adjustable damping
• Adjustable spring platform
• Height adjustment via bottom mount to retain full damper travel
• Bearing mounted upper front spring platform
• Dust boot to protect damper seals
• * some features are dependent on model

The BC Racing ER Series comes with separate compression and rebound damping adjustment. The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.

The external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit. The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes. The reduction in damping rate variations improves handling and ultimate on road and track performance.

By separating the adjustment for damping compression and rebound the ER Series allows you to dial the vehicle in to your exact needs. When braking hard whilst approaching a corner you want the car to transfer weight to the front tyres to maximise grip for the braking effort and also to allow you to trail brake into the corner without the car understeering.

The lower spring platform 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.

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment.

ZR Series Features

• 3-way adjustable damping controls
• Engineered for 100% track use
• Inverted damper design. (depending on models)
• Dual Piston design. (1 in res., 1 in shock)
• Teflon coated steel braided lines for external reservoir on inverted dampers and solid stem for double A-arm cars
• Custom spring rates available
• Completely rebuildable
• Monotube damper design
• Patented concave lower locking collar
• 1 year manufacturer warranty

BC Racing's new ZR Series Coilovers bring a 3-way adjustable track ready coilover system to racers from novice to pro for a price not seen before in the performance suspension market. Each ZR Series Coilover system offers independent low speed and high speed compression adjustment and separate rebound adjustment. They also offer full height adjustability independent of piston travel and spring preload.

On cars with McPherson struts the ZR Series comes standard with an inverted monotube damper with the steel braided Teflon coated line exiting the top of the damper to the external reservoirs that can be remotely mounted in the engine bay or boot. The ZR Series kits offer 30 clicks of rebound adjustment, 15 clicks of low speed compression adjustment, and 12 clicks of high speed compression.

The lower spring platform 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.

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment.

Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run.

DS Series Features

• Digressive Valving
• Pillowball upper mount
• Camber adjustable top mounts
• Aluminium top plates
• 30 way adjustable damping
• Adjustable spring platform
• Height adjustment via bottom mount to retain full damper travel
• Bearing mounted upper front spring platform
• Dust boot to protect damper seals
• * some features are dependent on model

BC Racing's DS Coilover system is built with digressive valving offering the same great benefits of the BR Type model and is considered a perfect choice for those who are looking for track biased coilovers. The digressive valving offers more stability and enhances cornering ability at low shaft speed which gives you a different ride from the conventional linear valving.

Unsprung weight is reduced by moving the oil and gas reservoir way from the hub and attaching it to the shell. Unsprung weight is vital to a cars performance as a lighter wheel and hub assembly which readily moves in response to road bumps will have more grip when tracking over an imperfect road. A high unsprung weight can lead to wheel hop over bumpy ground and will reduce the quality of the ride and also untlimate handling as anything that impairs the suspension ability to maintain contact between road and tyre will be of detriment to the cars performance.

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 consistant resulting in better performing suspension.

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 consistant steering geometry resulting in more predicatable and responsive handling.

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment.

The RM Series coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.
