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.

RM Series Coilover
The BC Racing RM series feature high quality damping adjustable monotube inverted dampers at the front or front and rear, depending on vehicle. The RM coilovers offer the majority of the features of the BR series but with the additional benefit of the inverted damper unit. Inverting the damper unit brings with it a number of advantages.
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.

ASP ADJUSTABLE SPRING PERCH BMW M3/M4 RWD/AWD G80/G82 (21+)
BC Racing's new adjustable spring perch (ASP) is an excellent solution for customers seeking a lowered stance but still require the OEM electronic damping system to remain functional. Compared with conventional lowering springs, the BC Racing ASP offers ride height adjustability that seamlessly allows users more flexibility to tailor their chassis to the needs of modern suspension, performance and style.

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.

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.
