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

This is the best suspension available for the ND Miata. It takes the fundamental nature of the Miata and improves on it. The roll is gone, replaced by quick reflexes - but not at the expense of travel or compliance. It's the same basic suspension used on our acclaimed V8 conversions, which has been praised for its organic, flowing feel.

This package combines our Fox suspension and sway bars.

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 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. We do offer them without springs if you'd prefer, just un-check the spring option - it'll still have everything else, just no springs. 

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 services are offered through Fox for $35/shock.

Reasonable - but be wary of road conditions!

My friend and I installed the Fox shocks in about 4 hours on my car (plus a couple of hours of prep and reading instructions). I also did the rear sway bar myself and paid Sake Bomb Garage in Fremont, CA to do the front sway bar and alignment.

The positives-
+ Instructions are very thorough and installation is not impossible for a first timer / novice mechanic like myself (just make sure you have all the right socket sizes and a good set of jack stands!).
+ The kit very complete - no additional hardware required.
+ The ride is more composed - it sits very steady on the highway (doesn't feel like the car is twitchy, like it used to be) and there's a nice amount of resistance when turning. I took it for an HDPE (caveat: as a novice) and body roll was effectively eliminated, as promised - although it still doesn't feel as smooth as the BMW M3 that inspired me to upgrade the suspension ;-).
+ The car sits very slightly lower - which evens out the height I gained when switching from 205 tyres to 215 tyres - and looks great.

The negatives-
- The default recommended settings (17 front / 22 back) were far too bouncy for me, which suggests that it was underdamped and I found myself getting thrown around over every imperfection. This is surprising because it was just me in the car and I'm a pretty average weight of around 165 lbs. Stiffening it up a bunch (recommended by the amazing FM support) helped a bunch: to 17 front / 16 back. Now it feels appropriately damped.
- I haven't yet found the best balance of handling / comfort - in fact, comfort seems lacking at all settings, so I ended up settling on the stiffer settings and dealing with the car's loss of comfort. This isn't an issue on well maintained roads and highways - unfortunately where we live, there are a lot of badly maintained roads (the East Bay / SF Bay Area in California). Ultimately, the trade off here makes me hesitate to recommend this to someone who commutes regularly in their Miata. I've heard the Ohlin's Long Stroke might be a better balance for the daily driver use case.
- This isn't specific to the FM kit and is relatively minor: access to the adjusters is a pain. You need to remove the trim from the rear and the front suspension strut bar makes it hard to adjust the front ones. (There is an aftermarket strut bar / brace that GWR sells that provides easier access to the front adjusters.)

It was a fun exercise, but were I to do it again, I might spend the extra money and try the Ohlins.

Great Kit and Great Customer Service

I've been waiting to write a review until i had some seat time in the car with the new suspension, to give my honest perspective. I had an issue with a faulty damper after 4-5,000 miles, but FM and FOX had it fixed for me free of charge. It also didn't take very long to receive it back from getting re-built at the FOX warranty center which was nice.

The suspension kit has been great otherwise. Its been installed for about 10 months and have loved it the whole time. The chassis roll has been greatly diminished compared to stock and inspires a lot more confidence when taking corners at speed. I have yet to make any adjustments to the sway bars or damper settings, but the out of the box setting FM recommend have been great! I might make some adjustments to the sway bar coming up soon, but we will see. The ride on the new suspension has been pretty comparable to the stock setup, although it might be a little more firm than stock. My dad has a stock 2019 club and he didn't really notice a difference to his car's ride as well, which was a relief considering i do a decent amount of driving and road trips with the car. Overall, couldn't be happier with this kit. Accomplished better cornering feel and "flatness" without ruining the ride quality for longer road trips. I'm excited to do a direct comparison next week when we have my car and my dad's car on a roadtrip through the blue ridge mountains. I'm sure he will be leaving there thinking about ordering a kit for himself.

Transformational

Changes the Miata from a "sporty" car to a true sports car. Annoying body roll? Reduced. Porpoising of the stock Bilsteins? Gone. Ride comfort? As good as, if not better than stock. And yes, the car looks cooler lowered, as well. All around fantastic upgrade.

Transform Your Miata

Purchased the sport springs version for my '16 Club. Customer service was excellent with delivery as promised. All the parts are top quality. The shocks are amazingly light! Installation was straightforward with the supplied instructions, although I did install the front sway using the "lower the subframe" method. After alignment to FM specs the car is transformed! Adjustments on the shocks allow me to add a bit of extra comfort for CA highway driving.
