Product Details

BC Racing ER Series Coilovers for the 2016-2024 Chevrolet Camaro (GM Alpha) put race-grade adjustability in reach of the serious track-day driver, with independent compression and rebound tuning at every corner. Every kit is extensively tested on the Camaro (With Magnetic Ride Control) chassis and refined until it balances ride quality with performance — the reason Camaro (With Magnetic Ride Control) coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

ER Series kits run a linear twin-piston design in a mono-tube body, with compression and rebound on separate external adjusters. That lets you fine-tune chassis balance corner by corner — stiffer front for turn-in, softer rear for exit grip, whatever the session calls for. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance — you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, custom spring rates, and custom valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of customization most brands reserve for their top-tier race kits.

Since 2004, BC Racing has grown into one of the most trusted names in aftermarket coilovers — not by racing to the bottom on price, but by pairing that price with real build quality, deep customization options, and a damper design any suspension shop can rebuild instead of replacing. These Camaro (With Magnetic Ride Control) coilovers arrive tuned for the Camaro (With Magnetic Ride Control) chassis and ready to bolt in — no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts — no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.

Reviews / Q&A

FAQs

Please read our FAQs page to find out more.

How much will BC Coilovers lower my car?

On average, Standard Drop allows about 1-2 inches of drop range below factory ride height. Extreme Low allows about 2-3 inches of drop.

Can BC Coilovers achieve factory ride height?

No. In most cases, factory ride height cannot be achieved.

What is a custom build vs off-the-shelf kit?

The stock level displayed on our website reflects the availability of standard “off-the-shelf” kits, unless noted otherwise in the product description. Selecting any custom options—such as Extreme Low, custom spring rates, Swift Spring upgrades, or top mount changes—will result in a custom-built kit. Please note: all series except the BR Series are built to order, with the exception of select popular DS Series kits that may be in stock. Also, some popular Extreme Low kits are in stock as well. To identify these, look for "Extreme Low" in the product title.

Will the struts be valved correctly?

Yes! The shocks and/or struts are always valved to match the spring rates you choose during a custom build. There is no additional cost.

Can they be rebuilt?

Yes, all BC Racing Coilovers can be rebuilt by purchasing individual replacement parts. For example, if a strut leaks, you can simply replace the shock cartridge.

Is there rush shipping available?

Rush shipping is not offered, but all in-stock kits ship very fast— most by the next day.

Customizing the coilovers in any way will delay the shipment by a few weeks on average.
