BC Racing ER Series Coilovers – BMW E92 M3 with EDC (2006–2013)

The BC Racing ER Series Coilovers for the BMW E92 M3 with Electronic Damper Control (EDC) are an advanced performance suspension upgrade designed for drivers looking for independent damping control, external reservoirs and greater consistency during demanding fast-road and track use.

The ER Series features 2-way adjustable damping, allowing compression and rebound to be tuned independently. Combined with external reservoirs, a monotube damper design and adjustable ride height, it provides significantly greater setup flexibility than the BR or DS Series.

Why choose BC Racing ER Series for your E92 M3 with EDC?

The E92 M3 is a highly capable performance platform, and the ER Series is aimed at owners who want more detailed suspension control than a conventional single-adjustable coilover can provide.

Independent compression and rebound adjustment allows the suspension to be developed around tyre choice, spring rates, alignment, vehicle weight and driving style.

The external reservoir design also makes the ER Series particularly suitable for cars that regularly see demanding road or circuit use where consistent damper performance is important.

Independent Compression & Rebound Adjustment

The defining feature of the ER Series is its independent 2-way damping adjustment.

Compression adjustment controls how the damper responds as the suspension compresses, while rebound controls how the suspension extends again afterwards.

Being able to adjust these separately gives experienced drivers and suspension specialists greater control over how the E92 M3 behaves under braking, acceleration, cornering and changing road or track conditions.

External Reservoirs

The ER Series uses external reservoirs as part of its advanced damper design.

These increase the available oil capacity within the suspension system, helping manage the heat generated by repeated damper movement during sustained hard driving.

For E92 M3s that regularly see longer track sessions, this can help maintain more consistent damping characteristics as temperatures rise.

Important EDC Information

This kit is intended for E92 M3 models originally equipped with factory Electronic Damper Control.

When the factory electronically controlled dampers are replaced with conventional BC Racing coilovers, the original EDC damping function will no longer operate as standard.

Depending on the vehicle and installation, an EDC cancellation solution may be required to prevent warning messages or system faults.

If you're unsure what is required for your car, contact us before ordering and we can help you identify the correct setup.

BMW E92 M3 Suspension Upgrade

The ER Series gives E92 M3 owners a highly adjustable platform for developing the car's handling.

Independent compression and rebound control allows the suspension to be configured around other chassis upgrades such as:

• Performance tyres
• Uprated anti-roll bars
• Adjustable suspension arms
• Polyurethane or solid bushes
• Chassis reinforcement
• Performance alignment settings

For track-focused builds, professional alignment and corner weighting can help maximise the benefits of the additional suspension adjustment.

Adjustable Ride Height

The BC Racing ER Series allows the ride height of your E92 M3 to be tailored around both appearance and performance requirements.

For road and fast-road cars, this allows the vehicle to sit lower with a more purposeful stance.

For track-focused setups, ride height should be considered alongside suspension geometry, available damper travel, 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, with alternative and custom spring-rate configurations available depending on your requirements.

The ideal setup will depend on:

• Vehicle weight
• Tyre type and grip level
• Road or track use
• Alignment
• Anti-roll bars
• Other suspension modifications
• Driver preference

For serious track builds, spring rates and damper settings should ideally be considered together as part of the complete chassis setup.

If you're unsure which ER Series specification is best suited to your E92 M3, contact us before ordering and we can help you choose the right setup.

BR, DS or ER Series?

The BR Series is the versatile all-round option for road, fast-road and occasional track use.

The DS Series adds digressive damping for drivers looking for stronger chassis control and a more performance-focused response.

The ER Series takes adjustability further with independently adjustable compression and rebound damping plus external reservoirs, making it better suited to serious fast-road and track-focused builds.

Maintenance & Servicing

The ER Series is a rebuildable high-performance suspension system and should be maintained accordingly.

The dampers, reservoirs, hoses, adjusters and mounting hardware should be kept clean and inspected regularly, particularly on cars used frequently on track.

Following BC Racing's recommended servicing procedures will help maintain consistent damping performance and maximise the service life of the suspension.

E92 M3 EDC Compatibility

This BC Racing ER Series kit is intended for the BMW E92 M3 produced between 2006 and 2013 with factory EDC.

Please confirm your exact vehicle specification before ordering, particularly if the car has had previous suspension or electronic modifications.

If you're unsure whether this is the correct kit for your M3, contact us and we'll help you identify the appropriate application.

What's Included?

The BC Racing ER Series is supplied as a complete coilover suspension kit for the applicable BMW E92 M3, including the vehicle-specific dampers, springs, external reservoirs and relevant adjustable components.

Exact top-mount, spring-rate, reservoir and EDC-related requirements can vary depending on the selected configuration.
