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
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!
DO THIS FIRST!!!
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.
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.
