BC Racing ER Series - Honda Civic FK/FN (2006-2011) (EU Models)

BC Racing ER Series Coilovers – Honda Civic FK / FN (2006–2011) EU Models

Upgrade the suspension of your Honda Civic FK / FN with the BC Racing ER Series coilover kit, designed for drivers wanting a more advanced setup for fast-road, track day and motorsport use.

Developed for European-market Honda Civic FK and FN models, the ER Series uses external reservoirs to increase oil capacity and improve temperature control during sustained hard driving. This makes it particularly well suited to repeated track use where consistency and heat management are important.

With 30-way adjustable damping, independent ride-height adjustment and multiple spring-rate options, the ER Series provides a highly configurable setup for serious performance applications.

External Reservoir Damper Design

The defining feature of the BC Racing ER Series is its external reservoir configuration.

By increasing damper oil capacity and improving heat management, the ER Series is designed to maintain more consistent damping performance during repeated high-load use.

This makes it particularly suitable for track days, time attack and motorsport applications where damper temperatures can rise significantly over longer sessions.

Key features:

• ER Series monotube damper design

• External reservoirs for increased oil capacity

• Improved temperature control during sustained hard use

• 30-way adjustable damping

• Independent ride-height adjustment

• Adjustable spring preload

• Improved body control and chassis response

• Rebuildable design

• Replacement components available

• Multiple spring-rate configurations available

• Custom specification options available

• Designed for European Honda Civic FK / FN models

Spring Rate Options

Available spring-rate configurations include:

8/8kg.mm – recommended spring rate for a balance of comfort and performance

12/8kg.mm – firmer, more track-focused setup for increased front-end support and chassis response

The recommended 8/8kg.mm configuration provides the most balanced option for fast-road and track use, offering strong chassis control while retaining more compliance than the firmer alternative.

The 12/8kg.mm setup increases front spring rate, making it better suited to more focused circuit use where reduced front-end movement, sharper response and greater support under braking and cornering are priorities.

If you are unsure which spring rate is most suitable for your Civic, please contact us before ordering.

Adjustable Ride Height & Damping

Ride height can be adjusted independently of spring preload, helping retain usable damper travel when lowering the vehicle.

The 30-way damping adjustment allows the suspension response to be fine-tuned according to road conditions, driver preference and intended use, from fast-road driving through to more demanding circuit work.

Vehicle Fitment

Designed for selected:

• Honda Civic FK

• Honda Civic FN

• European-market models

• 2006–2011

Exact compatibility can vary depending on model, engine and suspension specification.

Product Image & Specification Note

Product images are for illustration purposes only and may not show the exact specification supplied for every vehicle application.

BC Racing kits can vary depending on vehicle, spring rate, top mount configuration and other specification options. If you have any specific requirements, such as upgraded or alternative top mounts, spring rates, reservoir configuration or ride-height preferences, please contact us before ordering so we can confirm the most suitable configuration for your setup.

Fast Road, Track & Motorsport Performance

The BC Racing ER Series is particularly well suited to drivers wanting greater consistency and heat control than a conventional non-reservoir coilover setup.

The recommended 8/8kg.mm spring rate provides a strong balance for fast-road and track use, while the 12/8kg.mm configuration offers increased front-end support for more demanding circuit and motorsport applications.

Professional Installation Recommended

Professional installation is recommended.

A full four-wheel alignment should also be carried out after installation and once the final ride height has been set to ensure correct geometry, tyre wear and handling characteristics.
