Flyin' Miata sway bar set (ND chassis)
Tame the body roll! Front and rear sway bars.

Made in the USA

Exclusive to Flyin' Miata

Availability: In stock



If you're only going to do one thing to your ND, this is what it should be. Tame that body roll! Speed up transitions! Fine-tune your handling balance to your preference!

Sway bars are used to make your car corner flatter and react faster by keeping the body (and all the weight) under control. Ours are set up for neutral handling and are adjustable so you can tailor the handling of your Miata to your own driving style.
Our swaybars are hot formed from 4140 CrMo spring steel. This means they're stronger than the cold-formed bars found elsewhere. We've designed them to keep the same handling balance as your stock sways, but they have three settings in the front and three in the rear for fine-tuning.

The front bar is a tubular design with 1.125" diameter and 0.188" wall thickness, while the rear is a solid 0.625". Both have three adjustment holes and include polyurethane bushings, brackets and grease. The front bar also includes stoppers to keep it from sliding side to side.

Also available as individual front and rear bars if necessary.


Hole 1 Hole 2 Hole 3
Front 383 lb/in 454 lb/in 546 lb/in
Rear 119 lb/in 154 lb/in 207 lb/in

There are some kits on the market that reinforce the rear sway bar mounting brackets. We haven't figured out why, as they're a decently strong part that has shown no weakness either in our testing or during the MX5 Global Cup development. Our sway bar manufacturer and design partner can't come up with a reason to reinforce them either. While it may be possible to show on a test bench that these parts deform under hard use, what really matters is how the bars perform in testing. And in our testing, they perform very nicely.

Great suspension mod for the ND
Uninstalling the stock front bar and reinstalling this Flyin' Miata bar takes lots of patience and maneuvering if using the Flyin' Miata instructional video on YouTube. There are many other methods for removing the front bar, but Flyin' Miata's method makes it so you don't have to lower the sub frame which would mean having to get a new alignment. In total, the front bar took about 10 hours. It's an all day process. However, the rear bar is extremely easy to install and was on in less than 30 minutes. The result is an extremely good handling car with little to no body roll. Before this install, I noticed the car takes a second to settle into a corner. However, this fixed that problem too. The car really hooks up in the corners and inspires driver confidence.. The ride quality remains the same. I have both the front and rear bars set at the middle holes. Overall, it's a pain to install, but I'm happy with the outcome.

Just what my ND needed.
My 2016 ND now corners like a champ with the new sway bars. I followed the instructions that came with the bars as well as the YouTube video by flyin Miata completely. Sure, the front bars are a chore but once done the rears are a treat. I would most definitely recommend the upgrade as a priority (after giving the car some attitude with a new axle back muffler)

Awesome product!
Finish and quality of all parts are great. Since I'm a mechanic and have access to lifts install wasn't too bad. Back was easy, front was a bit more challenging. The result is awesome! I put these in at the same time as the new FM carbon fiber door bushings and it completely changed the car's handling. Body roll gone, more stable through bumpy corners, more control and more confident handling in any situation! Recommend doing the reinforcements at the same time for ease of installation.

question on stiffness rating
just installed the front and rear. it was PIA to get it in for the front.
The car becomes such a laser precision guided cornering machine. The steering response is incredible. I set it up slightly understeer for safety.

Just one question. What is the stiffness rating on these bar in Lbs/in??
I wonder how this compare to the OE front of 132 and rear of 41
Review by Tien Li / (Posted on 4/11/2020)
Great product at a reasonable price
The bars seem to be made of high quality material and with great craftsmanship. Rear bar didn't take too long, my only thing is that I suggest taking the wheels off. It makes it much easier to loosen the sway bar links, especially if you live in salty Pennsylvania like me. The front was a whore, but the result is well worth it. The driving dynamics of the car are greatly improved. No more squishy reactions in corners, less wheel hop going over bumpy turns. I also recommend getting the mount reinforcements in when you do the the sway bars as the reinforcements are easier to install with the sway bar out.

good parts... for the price
I have had these installed for a bit over a year now, 14 months to be exact. I really like the improvement in handling and the adjustable settings. I have the front set on full stiff and the back set in the middle. In the summer I am using Toyo r1r 205/50r16 tires, a big step up from the stock 195/50r16 Yokohamas (that are more than an inch wider despite what the size suggests, and much stickier too). The sway bars really help take advantage of the extra grip. Before next autocross season I am planning on having a proper alignment done and would like to install sports shocks and springs too.

Periodic lubrication of the bushings is required or they will start to squeak, especially over speed bumps. Also a good time to check the fasteners. I just did that today again (last did it in July) after not being able to stand the squeaking anymore.

However, I must say, the quality of these parts are not great. One of the rear brackets came with the holes cut in the wrong spot, too close together. I had to first bend the bracket to make it fit the bolts and later slotted out the holes with a dremel (and paint to cover the bare metal). The bushing was moving within the bracket when it was bent causing a clunk. Flying Miata was worthless to replace or exchange this small part- no response from my inquiry. The paint is flaking off the bars, especially around the sharp edges near the ends, and especially on the front sway bar. I also purchased the adjustable end links which are now completely rusted along with all of the included hardware. I will probably spray some fluid-film soon and hopefully that will prevent any further oxidation. I live well outside of the rust belt in Kentucky and there is no rust anywhere else on my car despite being nearly 4 years old now. I also only have to drive about 5 or 6 miles every day to work, maybe 5000 per year in total. So it's not like it is seeing a ton of use.

Installation IIRC was quite easy, the back was very simple (you could probably do it even without a hoist). The front required removal of the fan shroud and was a bit of a puzzle to get out... the factory workshop book requires dropping the subframe but that is absolutely NOT true if you use the technique FM gives in the manual.

Note from FM: Please reach out to us again, this is not normal. If you don't get an answer from email, please call.

All day install but 100% worth it
After 12 hours of install just for the front, I can say this is the single best upgrade you can do for the ND. I have not even put the rears on yet, but wow what a difference. The car not only handles much better and stays flat, but the car feels overall much safer on the freeway. This is how the car should've came! Remarkable what a single bar can do.

I tried to avoid removing the fan shroud, but wish I had just done it as this would have saved me hours. I had a problem where the bar was getting stuck between the chasis (flat body color flat part): once trying to get it over the subframe, and second trying to move it back over the steering rack and mount it even on both sides. I credit this to there not being enough rotational room because I didn't remove the fan shroud. I was missing by milimeters and ended up tapping the bar softly with a hammer getting it in both times. Also, don't think you can remove the stock bar at all without removing the fan shroud, airbox + bracket, battery + bracket, and a couple hidden coolant line bolts. I ended up cutting the stock bar with a small tubing cutter.

In summary, if I had to do it again I would cut the stock bar and remove the fan shroud. Just follow FM directions and remove the fan shroud. I don't even think I am going to get springs as I like the ride comfort, although it could use a drop. If you're debating this or springs first, get the sways 1,000,000%.

Note from FM: the good news for Haggler is that the rear bar is a complete walk in the park!

Game changer for handling
I’m going to join the throng of other reviewers by stating that this sway bar set (I also purchased FM’s end links) transforms the ND Miata’s handling from go kart —> 911. I have a 2016 Club Miata and really noticed how squirrelly the handling can. Body roll turning in, and while making quick transitions left me feeling almost a little unsafe as though I couldn’t quite trust where the limit of the Miata is. After having my local auto shop charge me an arm and a leg to install these (evidently the front sway bar install is a real pain in the ***), I immediately noticed how much more PLANTED the car becomes. “Point and shoot” weapon vs. Soviet RPG is now an accurate description of the Miata’s handling. Whether I’m going 10 mph or 80 mph, the car doesn’t roll or sway and I feel very confident turning in, throwing it around. My Mazda didn’t design the car this way in the first place is a mystery to me, but these are very much worth it and will put a capital Z in Zoom Zoom. Just get em!

Excellent inexpensive improvement.
Instructions were mostly straightforward and it was a pain in the a$$ to change the front. Take your time and swill a beer or two, you'll need it.
Fortunately my friend has a HF lift, I'd hate to try replacing the front on jack stands.

Tough Installation
Remove the airbox during installation! That's not optional! Battery tray *might* be optional, but just remove it. You'll save hours in total. Also I couldn't get the new bar over the steering rack, so I unbolted the rack to nudge it just a bit. Otherwise everything else in the instructions worked for me. Angled pliers helped me a bunch with removing the clips. Note: you might break a few.

Rear bar install is easy. I didn't even take the wheels off.

Settings: Front full stiff, driver rear neutral, passenger rear full soft. Anything stiffer in the rear and turn-in is darty with significant lift-off oversteer midcorner. Be warned.

Overall this is the best single upgrade possible to the suspension. My car flattened out in the twisties and I took 3s off my lap! This gets much more tire to the ground for more grip. Ultimately I would have preferred to pay more for a front bar with easier install. Now that it's in though, I'm very happy.

Note from FM: We'd love to make the install easier, but unfortunately it's all down to Mazda's design of the ND.

You won't be disappointed
If you want to switch up from the cute tossable little Miata, to the point and shoot weapon of choice, this is THE must have upgrade.
Follow the instructions, which are well put together. The front will be tedious for most, and I reccomend acquiring a long reach trim tool for the electrical connector mounts to the radiator support. But, it's not as intimidating as it may seem initially.
The end result is a car that stays flat, even with acceleration and braking. It truly does transform the vehicle.
The only concern I have, which time will reveal, is the quality of the bushings, and the finish of the bar. I anticipate a need for future service in that regard. As well, you will lose some of that feel as per the geometry of the rear suspension under extreme load.
Others mentioned better ride quality, however, it is the same, which is a GOOD thing.

All in all, if you want a truly serious improvement to handling, this is the one.

Highly recommend. Get a set.. you will not regret it.
Great price, quick shipping and the result is impressive. Take your time and follow the instructions carefully. That front bar install is a pita but so worth it. Tech tip, cut out a 21.5"x17" section of the shipping box and used it to protect the radiator. Worked perfectly and my radiator is still looking fresh. I had fm springs on the car already with fm alignment spec and these compliment them perfectly. No more miata common nervous twitchy turn in .. its direct and precise now without any strange secondary movement after steering input. Point n shoot.. it just does what you ask it. I set the bars up full stiff in front and full soft out back. No understeer noticed on the street and spirited windy back roads.

Could Not Believe The Difference, Before and After
FM has it right when they say "If you're only going to do one thing to your ND, this is what it should be." I could not believe the difference in both ride quality and cornering after I put these bars on my 2019 RF GTS.

I also took Eric's advice and added some new rubber and a performance-oriented alignment, and now I just grin ear-to-ear in every corner.

Great Kit At An Unmatched Price
I recently upgraded my daily driver from a lightly modified NA to a stock ND. Even though I knew body roll and pitching under acceleration/braking were an issue beforehand, I was still shocked at the amount of movement there was.
This kit solves that almost completely. The car is so much smoother and more neutral than before. Even on the factory tires, it can out-grip the NA on wider BFGs.

As far as I can tell, there's no better sways out there that even come close to this price. FM really did a great job with this kit.

As stated before, the front bar is a lot of trouble to change, but FM's instructions are spot-on. Take your time and try not to get too frustrated.

Rough install but amazing modification
Neither the front nor the rear brackets fit in the bolt holes. They had to be filed down like crazy to get them on which was super annoying. Other than that, the rear install was extremely easy. The front, however, was a nightmare! I removed the air box and battery box as many others did (not in the instructions). I don't see how any person could get their hands in there to disconnect the pesky connectors everywhere without this step! I would say about half of my total install time was trying not to break something on the radiator/fan shroud.

Note from FM: We can thank Mazda for the accessibility of the front bar, unfortunately! Thanks for the feedback on the bolt holes, we'll look into that.

Excellent set of sway bars!
Fantastic set of sway bars, very solid materials compared to the rear stock swaybar which I can flex with my hands. Took myself and a friend a few hours to install both, including with new bar end links. The rear took about 30 minutes total and the front took quite a while longer. As other's have said, the fan shroud is a bit of a pain as each connector unclips differently, just take your time and be patient and it'll come undone. Also removed the intake, coolant reservoir, battery, and wheels to make things easier. Definitely would recommend doing on a shop lift if you have access to one.

As for handling, I chose the neutral setting for front and back, the car immediately feels a lot more stable in corners and feels a bit smoother on the freeway in terms of not feeling as many of the small bumps. Definitely would recommend this kit!

Don't wait
This is the car I thought I had bought from the Factory. The sway bars have really made the car perform like I was expecting from Mazda. My only regret is that I waited so long to make the change.

Transformed My ND RF
I just finished installing your sway bar set (front & rear) on my 2017 ND RF. It's amazing. It transformed my ND into the vehicle I wish/thought I'd bought, And, as an added and unexpected bonus, the car rides much better. My wife used to wish she had some kind of grab handle to hold on to while riding in the passenger seat. With this sway bar setup she rides quite comfortably through all the twisties. Let me echo your statement, "If you're only going to do one thing to your ND, this is what it should be."

big difference in driving dynamics, relatively inexpensive,
I am new to a car improvement situation. Got a miata last year and developed 'miatitis'. I was sceptical but 2 unassuming metal rods made a lot of difference. I am impressed.

Worth it
HUGE performance upgrade for the ND. Replacing the pencil thin rear and the pinkie sized front sway bars is the most noticeable difference I've ever felt from a single mod.

Installation in the rear was quite simple. Off and on, no big deal.

Front installation took several hours. It's simple enough to take the air box, battery, and coolant overflow out.
Disconnecting the fan shroud and getting it out was an absolutely not-fun experience.
I was able to remove the OEM front bar without a problem. Disconnecting the fan shroud and removing it was tight and annoying.

Installing the new front bar was a different story. Even with the fan shroud removed and the radiator assembly hanging on by just the A/C lines, it was quite difficult to maneuver the new bar in place due to the longer geometry (adjustable-ness). I am not entirely sure how it got through, but I can verify the back of my radiator has a few more scuffs now.

Reinstalling all the parts taken out was a snap, probably 30 minutes of work...

Again, totally worth the trouble. Even with the club package, the ND is VERY roly poly when thrown through a turn. Currently, with the middle (recommended) setting, the car is more neutral, easier to drive, and predictable than before.

If you're thinking about getting coilovers for your ND, I would highly recommend this setup first for a perfect hold-me-over. (I am).

This sway bar set is a requirement not an option!
Had this sway bar set installed yesterday. Unbelievable improvement. It's a requirement not an option. My 2016 ND now feels connected and stable and no longer unpredictable. A modest investment you will not regret. If you're in the northeast, have Bob and Chris of Main Street Auto in Clinton, MA do the work. They know Miatas (MX-5s) and are great guys.

Best bang for your ND buck
The picture of the white ND exiting the corner says it all. ND's come from the factory with very soft suspensions. This upgrade is inexpensive, and makes a huge difference in the mountain roads (without negatively impacting normal driving). Installed both bars in under 4hrs, and took it for a drive on my favorite twisty back road. It was so much flatter through the turns; NOTICEABLY less body roll. This gave me greater contact patch on the road (which is much appreciated, not having a LSD). I was able to put down more power, and even felt the tail slide a few times - before the upgrade, I had so much body roll that I wasn't able to push it to this point. Just as I was thinking that it reminded me more of the characteristics of my e46 M3, I got stuck behind a guy who was going much slower through the turns... In an e46 330...
I can't recommend this upgrade enough.
Make sure your kit comes with the latest instructions - mine were 2 revs behind and left out an important step compared to the instructions online. Also, read through them fully before getting started - I wish I had broken the front lug nuts loose before I lifted the front end off the ground (I don't have an air impact wrench). Other than that, very easy to follow.
