Please note that although we expect orders to be unaffected, there may be the potential for a small delay with any 'out of stock' orders placed between 16.01.23 and 08.02.23 due to National Holidays.
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 characteristics 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.

ER Series Coilover
BC Racings premium flagship coilovers are the external reservoir ER Series 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.

We have had a small number of instances where the pillowball top mounts cause noise transmission on this specific application. If the potential noise could be an issue for you, we advise purchasing the ‘recommended kit’ at the top of this page instead.
The recommended BR-RN kit will not come with any top mounts as it is designed specifically to re-use the OEM top mount components.
We have had a small number of instances where the pillowball top mounts cause noise transmission on this specific application. If the potential noise could be an issue for you, we advise purchasing the ‘recommended kit’ at the top of this page instead.
The recommended BR-RS kit will come with non camber adjustable rubber top mounts which will eradicate the issue.
In a very small number of applications the RA front solid pillowball suspension top mounts can transmit noise into the cabin. It is very rare and is application specific. Customer can expect noise transmission on this application. The noise is not indicative of a fault with the product, its the nature of a solid pillowball top mount and the nuances of a very small number of car shells that combine to generate noise transmission. The noise is in the form of light knocking.
As noise transmission is a function of the pillowball and shell combination and you accept that noise might be present we will not accept returns of any of these kits as faulty due noise transmission. This does not effect the kits general warranty, only that pillowball noise transmission is not a warranty issue. We will not accept kit returns due to noise transmission.
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal to metal contact. In order to keep the two components from touching each other and so generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurised after carrying out this procedure. Please contact us on [email protected] for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.
