Description

"Slidey, neutral, sublime. You take the car by the scruff of its neck and just chuck it toward the horizon. It makes a stock car look lethargic, roll-heavy, almost stupid. And at no time does it even hint at biting you. Woof. So good." - Road & Track

"Ride quality, body and wheel control are all superb; without question, these are some of the finest conventional dampers available." - Motor Magazine

Meet the first excellent suspension for the ND Miata! We installed the first prototypes less than a week after we took delivery of our car, and we've been modifying and testing them ever since. We've had an SCCA hall-of-fame driver track test them and give us feedback. We've driven them on twisty back roads, on cross-country interstate runs and across all of our pet bumps on our various test loops. Then we revalved them and tested again.

The shocks are designed to keep the full range of suspension travel, including matching the massive 7" rear stroke. As with all our FOX shocks, they're aluminum bodied monotubes with adjustable rebound so you can fine-tune the shocks to your needs. Thanks to some careful fine-tuning of the valving, the car rides extremely well.

The Sport spring set is intended for performance street cars. It's comfortable enough for cross-country drives, but makes the car into a great back-road tool and very eager toy. It uses 400 lb/in front springs and 225 lb/in rear springs. On the RF, we use 250 rear springs to balance out the heavier rear end.

For track use, you can run higher spring rates. We've found 600 lb/in front and 350 lb/in rear works pretty well - those are the same rates used on the Global Cup Cars. We do not currently offer this spring set, but any good coil spring manufacturer can provide them.

If you choose one of the spring options they'll come with helper springs front and rear, as well as custom front upper mounts. This is a complete coilover setup with everything you need to install. 

There are a lot of little details on these parts that aren't immediately obvious. The springs sit on a high density plastic ring that acts as a bearing, allowing the spring to rotate on the perch without the expense of a bearing. The internal washers are disc ground for high accuracy, giving more consistent behavior of the shock. Even the body of the shock is given Kashima coat, which is a superior form of hard anodizing to protect the shock under the worst conditions. Even the shocks are light - 40% lighter than a Koni. Total weight per corner (springs, shocks, bushings, helpers) is 7.25 lbs for the front and 7.05 lbs for the rear. Made in the USA.

1-Year Limited Warranty for the original customer against defects in materials and/or workmanship. Custom revalving is available through Fox and it isn't expensive.

The single most impactful upgrade I have done to my Fiata

These are absolutely amazing. Dramatically improved my autocross/track performance. The ride feel is significantly changed for the better. As the title states, the most impactful change (of many) that I have made to my car.

Amazing upgrade!

First of all, fantastic service through Flyin Miata. They have always been my go to for parts. Been a customer and fan for 20 years or so. As for the Fox suspension, it is a must have. I was hesitant to spend that much for shocks and springs, but after installing, it was worth every penny. The recommended setup from Flyin Miata is spot on, no adjustments needed in my case. If you are on the fence about buying this, just do it, you won't regret it. I did have one minor issue though, when tightening the lower perch for the rear shock, the threads striped out with very little torque. The bolt was only in about 4 or 5 fine threads. Went to my local ace hardware and got new bolt that were 10 MM longer and was able to get the perch tight. Maybe it would be better if Fox included a longer bolt to ensure this does not happen to someone else.

Exceeds Expectations

These coilovers are amazing! The car feels incredibly agile and eager, and makes the car more enjoyable to drive. I was expecting the improved handling would come at a severe expense of ride comfort, however after driving with them for approximately 100 miles, it seems that the shocks have settled in and the ride comfort is better than expected. The ride is firm, but not harsh at all.

The instructions provided were good, however being that it was the first time I ever installed coilovers, I wish that there were more details to the instructions. Aside from that, I'm incredibly happy with my purchase and I hope ND owners take these coilovers in their consideration.

Fantastic

These things are fantastic!

Ok, I was finally able to install the Fox coilovers. The install was really easy, as far as car work goes. Maybe all that training on the 20-30 year old german cars paid off, because wow... So much more simple.

I really took my time, which added up to about 5-6 hours of actual work. The instructions were extremely clear, and made a lot of sense. I had the Eibach springs on there, and I didn't even need a spring compressor for the rears. The springs are so soft that all I needed to do was put some weight on the coils and that would release all pressure on the retaining nut and upper mount. So, anyone who is going to do this and has the eibachs, you should be just fine.

I ended up not disconnecting the sway bars at all. In the front it was actually super easy with the upper A arm bolts loose. Just lean on the hub a little with everything undone, push against the lower mount for the old strut, and it will fall right now. Then weave it up and out of the assembly. Put the coilover assembly in there, and attach the top hat to the car. That way, when you put downward pressure on the hub assy, it will not drop down along with it, and adds stability.

In the rear, I think the trunk lining and that fuel pump shield took more time than either one of the corners. Again, I didn't pull the sway bar links. What i did was release the upper nuts first, used my impact wrench on the lower bolt, and let it run itself out. Then I put a bunch of sudden weight on the hub, and shoved the lower part of the rear strut out of the way. It took a couple tries, but wasn't that hard. Use the force! Reassembly is the reverse of this procedure. Again, get the top nuts in place, and then you'll have to use a bunch of strength to get that lower mount of the shock into place. Really, you just need to get it on top of the link. Don't worry about lining up the bolt hole, yet. Once you have it in place, use a flathead screwdriver, inserted from behind the shock, between the lower control arm and the shock body. Then just rotate the screwdriver, and it will lift the shock up, allowing you to find the proper alignment to get the bolt into place. There ya go! Now you just need to tighten things up and you're all set.

I then drove around the block and thought i got the suspension to settle a bit. Then i went around and set the ride heights. I ended up just below 13" for the front, and then just above 13" for the rear, with .5" difference, per flyin' miata's recommended heights.

I set the shocks to the recommended stiffness, front at 17 from stiff, and rear at 22 from stiff. My first drive was astounding. I could even tell a difference when i was backing out of my driveway. My fiancee excitedly jumped into the passenger seat (she had been bugging me for hours about wanting to be there for the test drive), and we drove around SF for about 20m. Anyone who has been here is aware that we have what are likely to be the worst roads in the country. Rough, full of potholes, undulating, etc.. But this new suspension handles all of it with aplomb. I was overwhelmingly excited about how the car felt.

On Monday, I did my standard commute down 101 to San Mateo, which is about 20 miles. I can't begin to articulate just how much nicer the car is to drive. It is so much more comfortable, with a beautifully supple ride. Before, with the eibachs, the ride was busy, jiggly, and a bit bouncy. Any quick steering inputs would be met with significant roll and delayed steering response. Fast lane changes would feel wallowy and irritating. Now, all of that has changed. There is still body roll, but it is quick and extremely well controlled. The car responds beautifully to sudden steering inputs and inspires a lot of confidence.

Then yesterday, I decided that there wasn't enough rebound dampening at that stiffness setting, and upped it by 4 clicks. I figure that a good system for targeting proper shock stiffness is to go in 4 click initial changes to truly notice a difference and tell if I need to be stiffer, softer, or stay the same. If I need to change it, I will decide which direction to go, and move it 2 clicks. And then, if I'm still not satisfied, 1 more to truly hone in on the proper stiffness.

So, after driving it for another day, i think those 4 clicks were too much. It's just a little too jiggly and stiff now. So, I'm gonna back it off 2 clicks, and see how it goes. What i'm not completely sure about is how to determine if I need to change the front to rear balance. I know that the rear shocks help determine ride quality, so I think I need to work from that assumption.

So, verdict as of today? COMPLETELY worth every single penny. I was SO close to getting the Xidas, but the difference in price was nearly 700 after factoring in sales tax. I could almost justify a 500 dollar difference, but couldn't figure out 700 considering I'm not really ever planning on competing with the car, and this is really just an overly built street c...

WOW!!! These are that good!

Wow, simply wow. Yes folks, Flyin' Miata hit the nail on the head with these. Basically every Miata should come with these...something which even Dave Coleman, head of MNAO's R&D, who attended the 2016 FM Summer Camp event commented on.

The ride is sublime; never harsh or soft. They reside in the perfect Goldilock's zone heretofore never attainable in a Miata.

Further, and this is something that FM still really doesn't push, is the loss of unsprung weight (roughly half of the weight savings between the Fox kit and your heavy oem parts) is very noticeable; on the road or track. Don't believe me, read Sam Smith's take from the 2016 Miatas at Mazda Raceway Laguna Seca event here: http://www.roadandtrack.com/car-culture/a32131/miatas-at-mazda-raceway-miatagasm-mega-test/

My car is commented on as Car #3, as well as in the review of Car #8 and again at the conclusion of the article.
