When it comes to the Mazda Miata, one phrase defines its legacy—“handling is everything.” But if you’re still running tired factory suspension, you’re not experiencing what the Miata was built to do. Enter the TUKIMA BC Racing BR Series Coilovers, engineered to transform your 1989–2005 Miata (NA8C/NB8C) into a precision-handling machine.
Front Spring Rates: 62-150-10 Kgf/mm // Rear Spring Rates: 62-150-8 Kgf/mmThe BR Series Model is the perfect choice for street driving and the occasional road course or autocross duty.
Why Upgrade to TUKIMA BC Racing Coilovers
The BR Series offers the perfect balance between street comfort and track-ready stiffness. With 30 levels of damping adjustment, you can fine-tune your Miata’s suspension to suit your driving style—whether you’re carving mountain roads or attacking apexes on the weekend.
With easily accessible adjustment knobs for fine-tuning compression and rebound, ride height adjustment independent of shock stroke and spring preload, having a performance coilover system has never been easier.
Built for the Miata Purist
Each BC Racing coilover is custom-valved and height-adjustable, maintaining OEM geometry while drastically improving response and cornering grip. The monotube shock design ensures consistent damping under aggressive use, while the black anodized finish adds corrosion resistance and sleek style to your suspension setup.
The driver chooses how low or high the vehicle sits (no preset ride height here!) and a BC Racing patented concave lower locking ring keeps it locked securely in place. Most systems can be upgraded to pillowball mounts to proved the most feedback possible from the suspension and to sharpen steering response. BC Racing front camber plates also allow a driver to get the perfect alignment setup without compromise. Each of these features is offered, while providing a strong, attractive coilover system at a reasonable price.
Precision Meets Durability
The TUKIMA BC Racing BR Series Coilovers feature high-quality pillowball mounts, swift rebound control, and independent ride height adjustment—allowing you to drop your Miata without sacrificing suspension travel. Engineered for the NA8C and NB8C chassis, these coilovers are bolt-on and require no modification.

Solid stiff ride and you can go really low til 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 coiloversI 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

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.

Easy to install. I left the factory setting as the instructions indicated it was preloaded. I only drove on it apps town. But the feel like stock. Isn’t the firm to 10 on the front and 21 on the rear. I will get an alignment and corner balance the car like flying miata on youtube. So far so good.

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”
