BC Racing BR Series Coilovers for the 2009-2020 Nissan 370Z (Z34) offer the most affordable entry into coilover suspension without sacrificing performance, comfort, build quality, vehicle height, or handling. This is done by extensively testing each vehicle, then refining the coilover characteristics as many times as needed to ensure the most well-balanced and affordable aftermarket suspension conceivable.

BC Racing takes great pride in choosing spring rates for our off-the-shelf kits that strike the perfect balance between comfort and performance so you're never stuck with an oversprung suspension like many other brands sell. BC Racing offers one of the widest ranges of damping adjustment with 30-clicks of compression/rebound adjusted simultaneously on the BR Series.

With meticulously chosen spring rates, damper valving, and one of the widest adjustment ranges in the industry, you can't go wrong with the BC Racing BR Series Coilover System. BC Racing BR Series is the most popular coilover option from BC Racing.

    Good coilover

    They’re good budget-friendly coilovers. I was able to lower my 370Z a lot and it rides good too.

    Definitely get them

    At 110,000 miles, it was time to replace the OEM shocks and struts on my 2009 370z Touring (w/Sport package). The price point of the BC Racing coilovers caught my attention and after checking out the positive reviews on YouTube I went ahead and ordered the "true coilover" version. Installation was not bad, it only took 2 hours with help from my brother who is a certified mechanic (see my note below).Once it was done my Z looked slammed even at the highest height setting! Not only did my car look 10x better, but the handling and response was noticeable almost immediately (but then again I had worn struts). Definitely get these coilovers - I highly recommend them!!! NOTE: The regular version of these coilovers are the same price but are less adjustable than the "true coilovers" since they do not replace the OEM lower control arms which houses the rear springs. Just know going forward that if you go with the "true coilovers" that you also budget-in a set of aftermarket lower control arms and tension rods as well since you're going to loose those.

    I recommend these if you have a 370Z that’s primarily street-driven. I occasionally take mine to the track and these BCs still perform amazing. Great all-around coil over!
