FOX has been a suspension specialist for 40 years, and have won a huge range of motorsport events from the Paris-Dakar to the Indy 500. As a supplier to Ridetech, they've dominated Pro Touring recently. It's fair to say they know their way around shocks. They also understand the importance of proper suspension travel. Since they've also supplied shocks for the Ford Raptor, they also know how to build to an OE level of quality and durability. So, as you can imagine, we were pretty excited to work with them.

To develop these coilovers, we took measurements of the suspension's full range. FOX then designed a shock setup that would work throughout the whole range. After an initial fitting and test, they brought their race trailer out to our local track and we spent two full days with a two FOX engineers, three Miatas and two drivers to fine-tune the valving. We baselined against our current offerings, and used cars ranging from a typical FM II Miata to the 500 hp Targa Miata. This is the end result - a Miata suspension built from the ground up for us.

Our goal was for a high performance suspension that wouldn't punish on the street. We placed an emphasis on stability in corners, turn-in and body control combined with a very high level of grip. The adjustment was designed to primarily adjust the low speed rebound damping, which is mostly affected by body movements. You can adjust from a street setup to a hyper-aware track setup quickly and easily.

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 Torrington 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. The lower bearings have a Teflon liner so there's no need to grease them. Even the shocks are light - 40% lighter than a typical aftermarket unit. They are a monotube design.

The shocks have 5" of shaft travel. That's pretty spectacular, and it's part of the reason they can deliver searing track performance without punishing you day-to-day. When we put an experienced Miata driver and track instructor behind the wheel, he couldn't believe how comfortable they were on the street and how hard he could hit the berms. They just work.

Due to the long travel and maximum compression available, you can run just about any ride height with this setup. If you want to run low, the shocks will allow the suspension to compress as far as possible. If you want to run high, that long shaft travel will mean you still have droop available. You may have to use a longer spring for particularly high heights, such as a Baja application.

The standard spring set is 550 lb/in front and 375 lb/in rear. This is suitable for street use and track use, and it's what we use on the V8 cars we build for customers. On the V8 track car, we used 750/500, and the standard valving can deal with up to 900 lb front springs.

The springs will go loose at full droop. To avoid this, we do offer a helper spring kit for an extra $250. They won't make a difference to how the car drives, but they will keep the springs seated when the suspension is fully extended. It's mostly for ease of maintenance.

There may be some interference between the bottom of the shock and V8Roadster lower control arms. Some grinding will be required in this case. 2001-05 upper front control arms can also make contact with shock bodies depending on alignment, although this is less likely with the slim shock body of the Fox than some other setups. Please make sure there is no interference when you install your shocks.

The kit includes four shocks, bumpstops, front and rear springs (unless you choose "none") and some bushings. You will reuse your factory upper mounts and your existing lower bushing. If you'd like all new replacement parts, order the NA version. These shocks are built in the USA and can be rebuilt. 1-Year Limited Warranty for the original customer against defects in materials and/or workmanship. Custom revalving is available from Fox for $35/shock.

Wow, huge upgrade over stock

This is from the perspective of someone who is not a track driver. I just enjoy the local twisties here in Northern CA. I have a mostly stock 2000 NB (Racing Beat exhaust and cold air intake are the only mods). My NB had a stock suspension with 55k miles on it. It was bouncy. The stops disintegrated when I removed them. Installing these Fox coilovers was the first car project I'd done. It was not too hard after watching various YouTube videos. After doing the first one the rest were a breeze. Took 2 days overall (not including the exhaustive YouTube and research). Anyway, after install and test drive all I can say is WOW. The car feels so planted in the corners. Very little body roll. Eventually I stiffened it a couple of clicks from the FM suggested defaults. Still soaks up the bumps, but it's not exactly plush. But I wasn't expecting that. I was expecting it to feel like the most fun go-cart in world and I got that. So cool. My 16yo son loves it too. I only wish you could see the coilovers from the road. Alas the wheels/tires hide them. They are so pretty. :) Are they expensive? Yes. But worth it for me. I have ride height set at 5" rear, 4.5" front (from pinch welds to ground).

Better than the other guys

I have purchased 2 different sets of coil overs for my NB Miata. The first set was from a brand that comes on everyone�s favorite European supercars/Hypercars. I was underwhelmed I thought the dampening was very aggressive throughout the rebound adjustment range.These Fox coilovers are a different story. I purchased these shocks 1yr ago and these are the ones to buy. From the travel the shock has to the ease of adjustment for ride height. I have 225 200tw tires and I feel the off the shelf spring rates are great for these tires on a street car. These are definitely road car coilovers but, you can feel that off-road Fox DNA when going over bad bumps there�s a terrible expansion joint near me and these soak it up. I�m very pleased with theses coilovers over the 3 different brands I�ve used. Buy from people who deal with Miata�s all day!!

Great overall package

I put this suspension package in a 2000 SE in late January. The car previously had a stock suspension with about 93K miles on it. The difference was night and day. It is a great suspension. It rides very firm but not jarring. I did my first HPDE track event in March and it performed great. I'm still working on exploring the settings to improve it even further.

Amazing difference

I am not a suspension expert by any means. But I bought these shocks because I felt my 2003 V8 LS3 was missing something with respect to handling. The shocks I had were fine and did a nice job but somehow I wanted more. Installation was easy except for having to grind off a little material to fit the Fox rear lower mount into my V8 roadster lower control arms. First drive was amazing. I was not even sure what to expect but the car just felt "different". Around a very tight decreasing radius off camber turn I travel every day the car was flat and fast, much quicker than with the old shocks. As I continued to drive over various roads and turns I was searching for a word that fit the difference I was feeling when suddenly it occurred to me...the word is COMPOSED. The car is now composed in every situation. Rough road to freeway and all kinds of turns an amazing difference. Turn in is spectacular and I still have 16 adjustment clicks of firmness to go. Setting ride height which had been somewhat difficult with my old shocks was simple and precise. Finally have the exact ride height I want consistent from corner to corner. Overall perhaps the best purchase I have made for my car so far and worth every penny. PS: Get the helper springs.

fox shocks are winners.

The Shocks are awesome! just ran our first race with them In WRL at TWS. The drivers raved about them and the cars performance was amazing 4 laps in we had a 10 second lead on car 2 a Shelby Mustang and 20 second lead on car 3 a Porsche Boxter. Wow. Car is a 2000 miata with a na 2jz ge swap and arrow package, fox shocks with 750 # springs in front and 500# in the rear.
