BC Racing ER Series Coilovers – Honda S2000 AP1 / AP2 (2000–2009)
Upgrade the suspension of your Honda S2000 AP1 or AP2 with the BC Racing ER Series coilover kit, designed for drivers wanting a more advanced setup for fast-road, track day and motorsport use.
The ER Series uses external reservoirs to increase oil capacity and improve temperature control during sustained hard driving, helping maintain more consistent damping performance during repeated track sessions and demanding circuit use.
For this application, the kit is supplied exclusively with a 10/10kg.mm spring-rate configuration.
External Reservoir Damper Design
The defining feature of the BC Racing ER Series is its external reservoir configuration.
By increasing damper oil capacity and helping manage heat more effectively, the ER Series is particularly well suited to repeated high-load driving where consistency and thermal control are important.
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
-
Custom specification options available
-
Designed for Honda S2000 AP1 / AP2 models
Spring Rate
This kit is supplied with:
10/10kg.mm – recommended spring rate for a balance of comfort and performance
This is the only spring-rate configuration available for this application.
The equal 10kg.mm front and rear spring rates provide a balanced chassis setup with strong support under braking, cornering and rapid direction changes, while remaining suitable for fast-road and track-day use.
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, tyre choice, driver preference and intended use, from fast-road driving through to more demanding circuit work.
Vehicle Fitment
Designed for:
-
Honda S2000 AP1
-
Honda S2000 AP2
-
2000–2009
Exact compatibility can vary depending on market, model year 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.
Lowering Data Note: Any lowering figures shown in secondary product imagery apply only to the recommended kit specification.
Fast Road, Track & Motorsport Performance
The BC Racing ER Series is particularly well suited to S2000 owners wanting greater consistency and heat control than a conventional non-reservoir coilover setup.
With its 10/10kg.mm spring-rate configuration, external reservoirs and adjustable damping, it provides a strong all-round performance setup for fast-road cars, regular track use and more demanding circuit 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.
For more focused track use, corner weighting and a vehicle-specific geometry setup can also help make the most of the suspension package.
