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.

Be aware that in specific situations - stock (i.e., soft) springs, very sticky tires, and very aggressive driving - the front sway bar mounts can rip off. This isn't likely with stiffer springs (like our FM springs) or more gentle driving, but our reinforcement brackets (available above) are an easy install and a cheap insurance.  

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.

BEST upgrade ever!

If you are reading this, then you too have decided that you'll no longer tolerate the excessive body roll of stock sway bars! LOL.

I do all my own maintenance so I'm somewhat mechanically incline but I was still little intimidated based on all the reviews I've read. So I gave myself 8 hours to complete the install but I got it done in less than 4 hours on jack stands by myself. A friend offered to help but this is one man job. I think having an extra person working on it would made it more cumbersome.

I've watched several install videos on YouTube but by far, Flyin' Miata has the best instructions. After watching it several times, I felt comfortable.

For the most part, the install went without any issues. There are 2 things I would STRONGLY suggest that'll make the overall process much easier: 1) When removing the radiator hose nut (the one in front of sway bar), loosen the end links and brackets first so that you can move the sway bar around to give yourself more room to access the nut. I don't know why they didn't do it this way but it's much easier than removing the belly pan. 2) When removing the top nut on the sway bar bracket, don't use a box wrench! There's very little clearance between the top bolt and subframe so your wrench will get stuck. I almost couldn't get it out and this took me over half an hour of sweating and swearing! LOL

Other than that, follow everything else as is and you'll be just fine. Easy-peasy.

The final result... now it feels like a proper sports car! This is how it should have been came from the factory. I didn't like the suggested middle setting so I went with full stiff front and full soft rear. It feels very dialed in.

My advise, don't hesitate on this and just do it! You'll be so very happy you did.

Flattens cornering beautifully

It took a while to slide thess on, but the rear bar is easy enough a legless dog could do it. Contrary to the advise I saw online, I'd really recommend sliding the front on alone. It helps to be directly under the car. I wish the instructions placed more emphasis on the orientation of the bar, though, as I accidentally installed the front upside down and had to redo it.

The corners are flat, very limited body roll. Doesn't "transform" handling, but is the best upgrade for the ND to start with, alongside a short throw shifter.


Night and day difference in how the car handles after the sway bars, and the grille gets a lot of compliments

As the Brits say, "These do exactly what they say on the tin."

My 2023 MX-5 GT 6-speed was basically the perfect sports car for the street. Sure, it would want some upgrades for track use or autocross, but for the street it was nigh on flawless, except that it had a bit too much body roll, even with the KPC doing its thing. Was the body roll awful? Was it a dealbreraker? Did it rob the car of its "sports car" title?

Not at all. It was still a crap-ton of fun.

Nonetheless, I felt that flatter cornering would be even more fun. I always thought that that was all the thing needed to be perfect as a real-world sports car.

So, suspension mods, including lowering the car?

I don't know. Now we're talking big bucks, a possible decrease in streetable comfort, and, most of all, I'd have to worry about steep driveways, speed bumps, and all the other things we encounter every day that can easily tear up the bottom of a car that sits too low to the ground.

Nope. I simply wanted less body roll.

The Flyin' Miata sway bars absolutely did the trick. Now the car corenrs flatly, with zero loss of ride quality. It's the same car, until I hit a high-speed sweeper, or a series of fast S-bends. Now it just rips through them, like a go-kart. No body roll, but still wonderful compliance, and when I pull into that treacherous driveway in front of Popeye's I don't tear up the front lip spoiler. Other than flatter cornering, everything is the same.

To me, this is how the car should have been spec-d at the factory. Why not? There is no downside here.

this should be your first upgrade

A bit of a pain to install the front but not FM's faught but Mazda's design. I did alot of mods to my 23' RF all at the same time but this should be the first thing any new ND owner does. Follow the FM install video to a T. Took me about 2.5 hrs for both sways by myself in my garage on jackstands but truely transforms the car and makes it so much more enjoyable to drive.
