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.
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
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.
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.
They work as advertised. They eliminated body roll and turned this car into a precision weapon.
Warning to all: do not use a ratcheting wrench on the top bolts of the sway bar bushing mount. You can get the wrench stuck.
