BC Racing ER Series Coilovers – BMW M2 Competition F87 2018+
The BC Racing ER Series Coilovers for the BMW M2 Competition F87 (2018+) are an advanced, track-focused suspension upgrade designed for drivers looking for greater control over damping characteristics, improved heat management and a highly adjustable chassis setup.
The ER Series uses independent compression and rebound adjustment alongside external reservoirs, allowing the suspension to be tuned in greater detail than the BR, DS or RM Series. This makes it particularly well suited to M2 Competition owners looking to develop their car for demanding fast-road driving, regular track days or more serious circuit use.
Why choose BC Racing ER Series for your M2 Competition?
The BMW M2 Competition combines the compact F87 chassis with the twin-turbocharged S55 engine, creating a capable platform that responds well to a properly developed suspension setup.
The ER Series allows compression and rebound damping to be adjusted independently, giving you greater control over how the car behaves during braking, acceleration, cornering and changes in road or circuit surface.
External reservoirs increase damper oil capacity and help manage heat generated during sustained hard driving, making the ER Series particularly useful for cars that regularly see demanding track use.

BMW F87 M2 Competition Track Suspension
The ER Series provides a highly adjustable suspension platform for M2 Competition owners looking to develop their chassis beyond a conventional road-focused coilover setup.
Independent compression and rebound adjustment allows the suspension to be configured around performance tyres, alignment settings, spring rates and other chassis modifications.
For fast-road driving, the additional adjustment can be used to balance body control with suspension compliance. On track, it provides much greater scope to refine the car around individual circuit conditions, tyre characteristics and driver preference.
The ER Series can also complement upgrades such as adjustable suspension arms, uprated anti-roll bars, performance bushes and more aggressive geometry settings.
After installation, we recommend having the vehicle professionally aligned. Track-focused builds can also benefit from corner weighting and a geometry setup tailored to their intended use.
Independent Compression & Rebound Adjustment
The defining feature of the ER Series is its 2-way damping adjustment.
Compression and rebound damping can be altered separately rather than being controlled through a single combined adjuster.
Compression adjustment influences how the suspension behaves as the damper compresses, while rebound adjustment controls how the suspension returns after compression.
This allows experienced drivers and suspension specialists to make more precise changes to the M2 Competition's handling characteristics.
External Reservoirs
The BC Racing ER Series uses external reservoirs to increase damper oil capacity and help manage temperature during demanding driving.
Repeated suspension movement during track use generates heat within the dampers. Increased oil capacity can help reduce temperature fluctuations and maintain more consistent damping behaviour throughout longer sessions.
This makes external reservoir suspension particularly valuable on M2 Competition builds that regularly see circuit use.
Adjustable Ride Height
Ride height can be adjusted independently of spring preload, allowing the stance and suspension setup of the M2 Competition to be tailored without simply increasing spring compression.
For fast-road cars, this allows you to achieve a purposeful ride height while maintaining a properly configured suspension setup.
For track-focused builds, ride height should be considered alongside suspension geometry, alignment and corner weighting rather than simply lowering the car as far as possible.
Choosing Your Spring Rate
The ER Series is available with application-specific spring rates for the BMW M2 Competition, with alternative and custom spring-rate options available depending on the selected specification.
The ideal spring rate will depend on tyre choice, vehicle weight, suspension modifications, aerodynamic load and intended use.
A predominantly fast-road car may benefit from a more compliant configuration, while a dedicated track M2 Competition can make better use of increased spring rates and application-specific damper settings.
If you're unsure which specification is appropriate for your M2 Competition, contact us before ordering and we can help you select a suitable setup.
Maintenance & Servicing
The ER Series is a rebuildable, high-performance suspension system and should be inspected and maintained appropriately.
Cars seeing frequent track use should have the dampers, reservoir hoses, adjusters, mounting hardware and suspension components inspected regularly.
Keeping the dampers and reservoirs clean and following BC Racing's recommended servicing procedures will help maintain consistent performance and maximise the service life of the suspension.
M2 Competition Specific Fitment
This BC Racing ER Series kit is specifically designed for the BMW M2 Competition F87.
The M2 Competition uses a different BC Racing application from the earlier 2016-2018 original F87 M2, so it is important to select the correct kit for your vehicle.
If you're unsure whether this is the correct application, contact us before ordering and we'll help you identify the appropriate suspension setup.
What's Included?
The BC Racing ER Series is supplied as a complete coilover suspension kit for the BMW M2 Competition F87, including the application-specific dampers, springs, external reservoirs and relevant adjustable components required for installation.
Exact top-mount, reservoir and spring-rate specifications can vary depending on the selected configuration, so please check your chosen specification before ordering.
