Mazda MX-5 Miata Coilovers

A Miata on a good road turns in sharply, grips at the front and leans just enough to tell you what the tires are doing. The right kit keeps that feel and sharpens it. Here are all the Miata coilovers we carry, NA to ND, with BC Racing first.

Tell us if it is a street car, an autocross car or both. Call 1-800-460-9106 and we will help you pick a kit.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

BC Racing coilovers for the Mazda Miata

Four BC series on every Miata

BC Racing coilovers come in BR, DS, ER and ZX for every Miata generation, from the NA to the 2016 to 2023 ND Roadster. BC's NA and NB kit comes as its Extreme version by default, and BC sells a separate Extreme Low version for the NC. Not sure how low to go? Start with the standard kit.

BC Racing series for the Miata

BC Racing sells these four series for the Miata.

BR: NA to ND

BR is BC's single-tube (monotube) street coilover, with one 30-click knob that sets compression and rebound together. On a car this light, a modest drop and soft settings are often all a street Miata needs.

DS: NA to ND

DS has the same 30-click knob, plus a digressive piston. That gives more control as you turn into a corner, which is where a Miata driver feels it most.

ER: NA to ND

ER adds an external oil reservoir, and compression and rebound each set on their own over 30 clicks. Setting them separately helps when you tune the balance for autocross and track days.

ZX: NA to ND

BC calls ZX its "most track-tested" system. On the Miata it is sold for every platform, NA to ND.

Swift Springs

Swift Springs on a BC kit are ordered with our Custom Build for BC Coilovers option. Miata owners are among the BC buyers most likely to do it.

Torn between BR and ER? On a Miata it usually comes down to how often the car sees cones or a track. A street car rarely needs separate compression and rebound. A car that runs every autocross weekend usually ends up wanting it, so starting with ER can spare you a second kit later.

Eight other brands that make Miata kits

Each brand below makes kits for the Miata, and each design gives the car a slightly different feel. Call 1-800-460-9106 to talk it through.

Öhlins

Öhlins makes its Road & Track kit with DFV (Dual Flow Valve) for every Miata from the 1990 NA to the 2025 ND.

TEIN

TEIN makes four kit types for each Miata platform: Street Basis Z, Street Advance Z, Flex Z and Mono Sport. The ND kits include the RF.

KW is based in Fichtenberg, Germany, and makes separate kits for the NA and the NB. Its NC kit is listed as NC1, and its ND kit covers the RF.

Fortune Auto

Fortune Auto kits are hand-assembled in Powhatan, Virginia. It makes one kit each for the NA and NB, the NC and the ND, starting with the 1989 car.

Feal

Feal builds to order in California, with kits for the NA and NB, the NC and the 2016 to 2020 ND. Its engineers will talk spring rates with you directly.

Bilstein

Bilstein, the German maker of factory-fit (OE) shocks, lists two NC kits and three ND kits: B12 Pro-Kit, B12 Sportline and B14 PSS.

Ksport

Ksport makes kits for every Miata from 1990 to 2020, with separate NA and NB kits that change at 1998.

Swift Springs

Swift sells Sport Spec-R springs for the 2016 to 2024 Miata, for owners who want lowering springs on their own.

Kits for the street, autocross and track days

Weekend street driving

Lower it a little, keep the damping soft, and let the car move. A Miata on stiff settings and a bumpy road stops being fun fast.

Kits to look at: BC Racing BR, TEIN Street Basis Z, Bilstein B14 PSS (NC, ND)

Autocross: cones and a stopwatch

Autocross rewards a car that changes direction quickly. Adjustable damping helps you tune the balance for each course.

Kits to look at: BC Racing DS or ER, TEIN Flex Z, Ksport, Feal

Track days

Longer sessions mean heat and repeated loads. Kits with external reservoirs or racing-derived valving are built for that kind of use.

Kits to look at: BC Racing ER or ZX, Öhlins Road & Track, KW, Fortune Auto

Miata kits, generation by generation

Each kit links to its page, where you will find the current price, the exact years it fits and the specs.

Notes in BC kit names: "Extreme by Default" means the kit ships as BC's Extreme Low version as standard, built shorter for a lower drop.

2016 to 2025 Mazda MX-5 Miata coilovers (ND, 4th generation)

Codes: ND, RF

Check first: For ND Miata coilovers, BC Racing lists its kit for the 2016 to 2023 Roadster. KW and TEIN include the RF (the folding hardtop) in their ND kits, so RF owners should check the kit details first.

Before you buy: what Miata owners run into

These are the problems Miata owners report most often on forums and in recalls and service bulletins, and what each one means for your coilovers.

Tired or poor stock bump stops

NA, 1990 to 1997, and NB, 1999 to 2005

A Miata parts specialist that sells replacement stops calls stock NA bump stops terrible and says NB stops degrade and can crumble. On the Grassroots Motorsports forum, one NB owner is buying new stops after hearing they are a must-have. A lowered Miata reaches its bump stops sooner.

Before you install: Check whether your coilover kit includes bump stops, and if it reuses the stock ones, inspect them and replace any that are cracked or crumbling.

Bent or crushed frame rails

NA and NB, 1990 to 2005

A Miata parts specialist says the factory frame rails are easily damaged by bumps and jacking mistakes. One NA owner on a forum blames crushed rails on a tire shop jack, and members say it is mostly cosmetic unless the rail has split or rusted. A lower car scrapes more and is harder to jack.

Before you install: Inspect the rails before lowering, use proper jack points or a low profile jack, and tell tire shops not to lift on the rails.

Body roll from the factory setup

ND, 2016 on

Grassroots Motorsports describes the stock ND as having designed-in excess body roll, and an ND RF owner on its forum agrees. Common fixes are stiffer anti-roll bars and uprated dampers, though one well known Miata tuner rates the stock suspension highly. Owners often pair coilovers with sway bars, and both change front to rear balance.

Before you install: Decide on sway bars at the same time as the coilovers, and plan an alignment with the camber you want once ride height is set.

The Miata story

Miata history: built for balance

The MX-5 Miata debuted at the Chicago Auto Show in February 1989, and mass production began that April at Ujina Plant No. 1 in Hiroshima. Mazda built its one millionth MX-5 in April 2016. The idea behind it has a name, Jinba-ittai, which Mazda translates roughly as a oneness between horse and rider.

Mazda built that feel into the suspension, which is why Miata coilovers are more about balance than stiffness.

1989

Wishbones at both endsMazda designed the first Miata's suspension from a clean sheet of paper. In a first for Mazda, it used double wishbones front and rear, and engineers made them as light as a strut setup.
2006

NC: wishbones up front, multilink at the backThe third-generation car kept double wishbones at the front and moved to a new multilink rear with long links. That is why NC kits stand apart from NA and NB kits.
2016

ND: lighter againThe ND kept the front double wishbone and rear multi-link layout. Mazda made it the lightest MX-5 since the first generation, with a suspension 12 kg lighter than the NC's.

Pick a kit that keeps the Miata balanced, and the car will still feel the way Mazda meant it to.

Before you order: Miata questions

Which coilovers fit my Miata?

Find your generation first: NA and NB (1989 to 2005), NC (2006 to 2015) or ND (2016 on). Most brands cover the NA and NB with one kit, and the NC and ND each have their own. Not sure? Call 1-800-460-9106.

Do the NA and NB Miata take the same coilovers?

Usually. BC Racing, Fortune Auto, Öhlins and TEIN list one kit for both, and Feal's NA and NB kit is listed up to 2004. KW and Ksport sell separate NA and NB kits.

Do I need a different kit for the MX-5 RF?

Check the kit details. KW and TEIN include the RF in their ND kits. BC Racing lists its ND kit for the Roadster.

Which BC Racing series fit my Miata?

BR, DS, ER and ZX are sold for every generation, NA to ND. BC's ND kit is listed for the 2016 to 2023 Roadster. BC does not sell its other series for the Miata.

Can I add Swift Springs to my Miata?

Yes, two ways. Swift Springs on a BC Racing kit are ordered with our Custom Build for BC Coilovers option. Swift also sells Sport Spec-R springs on their own for the 2016 to 2024 Miata.

Which brands cover every Miata generation?

Öhlins, Fortune Auto, Feal, TEIN, Ksport, KW and BC Racing all list kits for the NA and NB, the NC and the ND. Bilstein starts with the NC.

What warranty comes with a BC Racing Miata kit?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. Each of the other brands sets its own warranty terms.
