Overview & features
The ER Series is where tuning your car gets serious. Thirty clicks of independent compression and rebound adjustment let you dial each in on its own, so you can fine-tune balance corner by corner. Remote reservoirs add oil capacity and shed heat faster, keeping damping consistent through repeated hard laps, with an optional check valve to sharpen response further. Built for drivers who've outgrown single-adjustable coilovers.

About the ER series
Outgrown single-adjustable coilovers on your car? The ER adds 30 clicks of independent compression and rebound plus remote reservoirs, so damping stays consistent lap after lap while you fine-tune balance.
This kit is configured as ER-OFF — external reservoirs at both ends, plumbed away from the damper body so fluid volume and cooling capacity go up and damping stays consistent under sustained load. Top mount type isn't fixed by the series here; it's specified per vehicle, so check the fitment for your car. It ships assembled and ready to bolt on out of the box — allow time at fitting to choose a mounting position for the reservoirs.
Common questions
Will this kit fit my vehicle?
Yes — this kit fits all body styles.
If you have a non-standard chassis or factory suspension upgrade, contact us before ordering and we’ll confirm fitment.
Can I adjust ride height after installation?
Yes. All BC Racing coilovers use full-thread body construction for continuous height adjustment without affecting damper travel.
We recommend a wheel alignment after any significant ride-height change.
How do I adjust the damping?
Damping is adjusted via the top-mounted dial — turn clockwise for firmer, counter-clockwise for softer. Always start with all four corners at the same setting and adjust in equal increments.
