BC Racing BR Series Coilovers are perfect for driving your car on the street and occasional road course duty. Easily accessible adjustment knobs allow for fine tuning your suspension's compression and rebound. Want to go lower? Simply adjust your vehicle's ride height through the shock body. Choose how low or high you want your vehicle's no preset ride height here, and BC Racing's patented concave lower locking ring keeps it locked in place. All BC Coilovers come with pillowball mounts to provide the most feedback possible from your suspension and to sharpen your steering response. Available front and rear camber plates also allow you to get the perfect alignment setup without compromise. All this while providing a strong, reliable, and attractive coilover system at an affordable price.

Ask a Question
  • what are the swift springs for ? i have a '16 370z and not sure if these are necessary or not.

    They are not necessary. They're just a better quality spring. http://www.swiftsprings.com

  • Would a 11k front , 9k rear spring rate on standard springs, be considered custome and the lead time would be 2-4 weeks before shipping?

    Yes, any rates other than the ones that come standard (10k front/8k rear) will have to be custom built and take about 3-4 weeks to ship right now.

  • Hello, I was wondering how close to stock ride height could i adjust these coilovers? Are other suspension components necessary for this install like camber arms, control arms, etc.? thanks!

    It varies per vehicle but these coilovers aren't made to keep the car at stock height. BC Racing states the average range of lowering is from 1 to 3 inches. The additional suspension arms depend on your drop and desired alignment. 

  • For a 09 370Z, do they come with camber plate for the front?

    Camber plates aren’t available for this vehicle due to the suspension design. 

  • what is the maximum low br series coilovers go in the rear for z34

    The standard drop is 1-3 inches on average, and extreme is 2-4 inches. This does vary per vehicle though and is an estimate.
