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.
This is the kit we recommend for the best balance of performance and comfort, designed by the factory to have the best overall compromise of spring rate, ride height range, top mount design and damping rate to suit the majority of car owners.
It is more than capable of dealing with fast road and track work but also retains a high degree ride civility so the car can still be used for mundane duties and long journeys without the ride becoming tiring.
Within each series, there are different types/configurations that you can select to best suit your application. Contact us for expert advice if required.

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.
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.
