The term "coilover" is short for "coil spring over shock". A coilover is part of the car's suspension made up of a shock absorber inside of a coil spring. This provides damping without torsional loads. Most coilovers allow adjustment of ride height and preload, using a simple threaded spring perch similar to a nut. More advanced adjustable coilover systems use a threaded shock body, along with an adjustable lower mount for ride height adjustment, while an adjustment knob is used to adjust damping. Switching the spring for one with a different spring rate will change the stiffness of the car's suspension. A higher spring rate is stiffer than a lower rate.

A coilover kit is considered custom when you choose custom spring rates, Extreme Low, upgrade to Swift Springs, or any alteration other than how they come standard from BC Racing.

The amount of drop varies based on the vehicle. On average, standard kits drop a vehicle 1-3in, whereas Extreme Low kits drop your car 2-4in. Unfortuately BC Racing doesn't provide exact drop rates per vehicle.

The cost to upgrade to Swift Springs for a full kit (all four corners) is $320. The cost to upgrade only the front or rear is $180.

No. When you upgrade to Swift Springs, we only charge you for the cost of the Swift Springs. This is discounted as well since we do not include the BC Racing springs. We also do not charge for build labor. 

Rear damping extenders attach to the adjustment knob for damping on top of the coilover. They allow for easy adjustment in many cars in which the trunk liner covers the top of the coilover. You simply cut a small hole in your liner and feed the extenders through. The extenders consist of a flexible steel cable with a coating on top to prevent corrosion or scuffing of your interior. 

Due to the factory design of some vehicles' suspension, camber plates are not always available. Camber plates will generally only work on a McPherson strut design. Some car manufacturers like Lexus and Honda use A-Arm style suspension on their cars, both front and rear.  This style of suspension will not support the use of a camber plate, so you would need to use either an adjustable arm/link, or other camber adjustment setup to dial in your alignment.

We don't show inventory levels on our website to ensure our custom-built products are still displayed in search engines. For this reason, please contact us if you would like to check inventory on any product. We usually respond within a few minutes. BC Racing stocks most BR Series kits and some DS Series. Almost all others are made to order.

BC Racing only includes end links if the coilover kit requires them. Most cars do not require new end links.

Yes. We always recommend an alignment any time a set of coilovers are installed or when your ride height is adjusted. Changes to your suspension can make the vehicle dangerous to drive. We also recommend a professional alignment to avoid excessive tire wear.

Yes. All coilovers come preloaded. Be sure to adjust your ride height properly so that you don't accidentally adjust the preload.

No. You will need to choose your desired ride height and damping settings. A good rule of thumb is to start in the middle and work your way either stiffer or softer depending on your needs. 

BC Racing offers a one year limited warranty against manufacturer's defect. We recommend you register your purchase through BC Racing's Warranty Registration.

Yes. When you increase the spring rates, they can decrease the amount you can lower the vehicle. Very stiff spring rates will not compress as much from the vehicle's weight, thus resulting in less of a drop. Please consider this when selecting custom spring rates!


We accept all major credit cards, Apple Pay, Amazon Pay, and PayPal. We also offer Affirm for financing options and payment plans.
