Product Details

BC Racing BR Coilovers for the 1990-2005 Mazda Miata/MX-5 (NA8C/NB8C) 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 Coilovers are the most popular coilover option from BC Racing, and one of the most popular coilovers in the automotive tuning industry.

    Lots of drop!

    Solid stiff ride and you can go really low until your fenders rub 👌🏽 very easy to adjust how stiff or how soft you want your ride i highly recommend this if you're looking for good solid coilovers. I drive on the high way a lot so I was looking for a stiffer ride, but with the setting on the stiffest its way too stiff probably perfect for track use very noticeable difference from stiffest to softestDon't cheap out on coilovers these are solid for street high way or even the trackIf you're looking for stiffer ride, smoother ride, abd good quality coilovers this is for you you'll immediately feel the difference in ride once you install them

    Every car needs this!

    Changed my stock 95 Miata suspension for these coil overs and the car handles amazing. Makes your ride very adjustable and will make your ride turn like a go cart! I was hesitant in spending the money but it's like everyone said to me, "worth every penny"

    So adjustable.

    Just when I thought my Miata couldn’t handle any better I was proven wrong. I had mild understeer when I was really pushing it and that completely went away. Car stays so flat in corners. Being able to adjust ride hight independent of spring rate is really nice. There is a ton of range in dampening adjustment. They look to be built really well and install was pretty straight forward, no spring compressor needed.

FAQs

Please read our FAQs page to find out more.

How much will BC Coilovers lower my car?

On average, Standard Drop allows about 1-2 inches of drop range below factory ride height. Extreme Low allows about 2-3 inches of drop.

Can BC Coilovers achieve factory ride height?

No. In most cases, factory ride height cannot be achieved.

Will the struts be valved correctly?

Yes! The shocks and/or struts are always valved to match the spring rates you choose during a custom build. There is no additional cost.

Can they be rebuilt?

Yes, all BC Racing Coilovers can be rebuilt by purchasing individual replacement parts. For example, if a strut leaks, you can simply replace the shock cartridge.

Is there rush shipping available?

Rush shipping is not offered, but all in-stock kits ship very fast— most by the next day.

Customizing the coilovers in any way will delay the shipment by a few weeks on average.
