Popular BC Racing Coilover Accessories
This collection highlights the most popular accessories and upgrades for BC Racing coilovers, the parts owners reach for most often once their kit is installed. The two standouts are different spring rates to change how the car rides and rear damper extenders that make adjusting damping quick and easy. Together with camber plates and other setup hardware, these are the upgrades that help you get more out of a coilover kit you already trust.
The Upgrades Owners Add Most
A coilover kit is a starting point, and these popular accessories are how owners fine-tune it. Changing spring rates is the most direct way to adjust ride characteristics, letting you firm things up for track duty or soften the setup for a more comfortable street feel, and BC Racing offers custom rates alongside Swift Spring upgrades for the most refined response. Rear damper extenders are the other favorite, relocating buried rear adjusters so you can change damping in seconds instead of pulling apart the interior. Camber plates and adjustable top mounts round out the list, helping you correct alignment after lowering to protect your tires and sharpen grip.
Choosing the Right Accessory for Your Setup
Because these parts are built around BC Racing coilover bodies and spring dimensions, the goal is matching the accessory to your specific kit and vehicle. Most BC Racing coilovers use a 62mm inner diameter spring, and extender and top-mount options vary by application, so confirm the fit on the product listing before ordering.
