Here we have answered some of the most common questions about BC racing coilovers.

BC Racing Coilovers - BR Type      


  • 1. Can I request a custom spring rate or custom damping for my BC Racing coilover kit?

    Yes! We have the ability to set up your coilover kit with custom spring rates and damping based on your needs.  If you have already researched what spring rate you want, then simply enter your desired spring rates on the order page in the  comment box during checkout. Damping will automatically be matched to a spring rate other than the standard rate out of the box (no need to request damping too).  If you have custom specs for spring rate and damping then please email us directly.  Be advised, the standard kit that BC Racing puts together is a very good match for most cars, and uses so not everyone needs a "custom" kit!      

Note: Custom Spring rates will require 1-3 weeks build time since they are built to order.  


  • 2. Can I get an "Extreme Drop" kit or a lower than normal BC Racing coilover kit?

    Yes! We have started offering the Extreme Drop kit for most vehicles upon request.  This includes a shorter spring and shock combo to allow for a lower overall drop.  This will also affect how high the kit can go, so there is a trade off and you should consider this before ordering. We only recommend the Extreme Drop option for those who are looking to go very, very low, slammed, stanced, etc. We do not recommend this setup for serious track vehicles unless you really know how to setup the suspension around them.

  • Most of our popular coilover kits now have extreme low options built right into the product pages. You can select the option before adding them to your cart.  Please remember most extreme low builds are custom built to order and can take 1-3 weeks. 


  • 3. Do you offer the Swift spring upgrades?

    Yes! We offer custom Swift spring upgrade kits.  The standard coilover springs are swapped out for Japanese built Swift Springs and arrive ready to go. The Swift springs are a high quality spring and will provide better ride quality as well as overall handling.  Swift only makes springs, so they are some of the best springs available on the market, which is why they perform better than the standard BC Racing springs (although there is nothing wrong with our standard springs).

    Swift springs have a more consistent spring rate over the entire compression range. This means they do not get much stiffer as they compress, keeping the ride smoother and more predictable. You won't get as much of a jolt as you  hit bumps. They also have less coils per spring, which allows them to compress much farther, this provides more compression range and will soak up bumps and dips better  The response times are also superior to standard springs to provide sharper turn in, and better handling on curvy or bumpy tracks.

  • 4. What are Extenders, and do I need them?

    Extenders are an add-on accessory that is attached to the damping adjustment knob on top of the coilover.  The extenders consist of a flexible steel cable with a coating on top to prevent corrosion or scuffing of your interior. They are a HUGE help for adjusting your rear damping settings on most sedans and coupes. Without extenders every time you want to adjust the damping you have to remove your rear trunk liner or seats.  With the extenders you just poke a small hole in the liner and they slip right through, allowing quick and easy adjustment!

  • 5. Why aren't camber plates available for some vehicles?

    Camber plates are not available on some kits due to the factory design of some vehicles.  Camber plates will generally only work on a "McPherson strut" design.  Reason is because some car makers 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.  If you ever see a listing that says a Lexus/Honda kit includes camber plates, many times it is not correct. These listings are usually generic listings that cover many makes of cars.  The kits will generally ship with rubber insert upper mounts, which are ideal for street use,  Pillowball plates are optional.  However the pillowball plate is just a solid steel bearing, it has no adjustments. We can provide you a number of camber adjustment parts if you'd like, just email us and we can work up a quote for those parts. We carry popular brands such as SPC, Cusco, Whiteline etc, and they offer camber solutions for many A-Arm vehicles.

  • 6. Do the BC Racing Coilovers come with new endlinks?

    If the coilover kit requires a new set of end links BC Racing includes them (some BMW, Acura kits, etc.).  Most cars however do not require new end links, so the kit can be used with stock links.  

  • 7. How do custom orders work and how long does it take to ship?

    All custom kits are built at the BC Racing facility and ship ready to install. There is nothing you need to do on your end once they arrive except install them onto the car and adjust them to your specs!  We do need to explain that there is a short lead time on any custom orders. Custom orders are orders such as (custom spring rates, dampening, swift spring kit, extreme low, etc.) These orders can take 2-3 weeks to ship, as they are custom built to order. This time starts about 24-48 hours after placing your order through our site.  We will contact you if there's any additional lead times.

  • 8. Can you install the BC coilovers on my vehicle?

    Yes! has a full-service facility in Dayton Ohio.  We are fully capable of installing your coilovers at our shop location. Our staff is very familiar with BC Racing coilovers and suspension setups,  we can make sure your install goes smoothly and is done correctly the first time.  We also offer alignments with installs.

  • 9. Do I need an alignment after my BC coilovers are installed?

    We highly recommend getting an alignment anytime a set of coilovers are installed.  The camber and toe settings will be changed some times drastically due to the change in height. These changes can make the vehicle dangerous to drive. We also recommend a professional alignment to avoid excessive tire wear.

  • 10. Will these BC Racing coilovers be good enough for track or competition use?

    Yes! If you need help choosing a kit that will hold up to whatever type of racing you are doing, be it track-days, rally, road-racing, autocross, etc. Contact us through live chat or email and we will be happy to help!

  • 11. How long does it take for a BC coilover kit to ship to my door?

    We process your order within 24-48  hours of receiving it on our site.  If the kit is in stock it will ship to you within 72 hours. Shipping within the lower 48 is normally 3-5 business days and shipping to Canada is usually 5-7 business days.

    If you are Shipping outside of North America, delivery times can vary. So please contact us for more info if you need an ETA for an international order.

  • 12. Do the BC coilovers come pre-set out of the box?

    No, BC Racing does not pre-set ride-height or damping from the factory. You, or the install shop, will need to set the height on the vehicle. The damping settings can be set to your preference, don't be afraid to experiment! A good rule of thumb is to start in the middle and work your way either stiffer or softer depending on your needs. You will also need to set preload on the springs, again all the settings need to be to your driving style and preference to keep at it until you get it exactly how you want it.
