Improved! The rear shocks now have offset bushings for extra clearance between the spring and the halfshafts. This gives you a wider range of height adjustment.

Our V-Maxx Classic suspension is very popular, but there's one thing missing from it: adjustable damping. So we worked with V-Maxx to bring an adjustable set to market. They call it the XXtreme.

The XXtreme Track Pack comes with stiff 504 lb/in front and 336 lb/in rear spring rates. They're aimed at cars that spend most of their time on the track. It can still be driven on the street, but it is stiff. Early Miatas should have some sort of chassis reinforcement in order to take full advantage of these spring rates. If you'd like a softer option more suited to street use, these are also available with the Sport spring rates for the same price. The springs are also available separately if you'd like to have multiple sets on hand.

So what makes them work? One of the problems with a lot of coilover setups is that the spring can go loose under full droop. When that happens, there's nothing to extend your shock any further so you've essentially reached the end of your suspension travel. The secondary spring in the V-Maxx coilovers helps to extend the wheel further and give more useful suspension travel.

The secondary springs are 112 lb/in, which gives them enough strength to overcome the damping of the shock. On most cars, they are just barely fully compressed at rest. Other systems will use helper springs as soft as 5 lb/in, which simply isn't enough to do anything useful when you're moving down the road.

Since the spring perch is adjustable, you have full control over ride height and cornerweighting. A 1/2" shorter rear shock body gives extra compression travel for improved ride and handling, even at lower ride heights. The stock upper mounts are retained. They have a two-year warranty and are available in a TUV approved version with different spring rates.

They're not quite in the same league as the Fox in terms of outright speed, but they do offer excellent value and are a good choice for someone who wants an inexpensive coilover setup. Includes both sets of springs, four shocks, adjusting tools and bumpstops.  Not compatible with FM's rear upper mounts, as this combination provides more compression travel than the suspension can physically deliver.

Please note that these were designed as a performance setup, and thus work best at a lower-than-stock ride height. We recommend setting them at approximately 11.5"-12" in the front and 12"-12.5" in the rear, although they can run higher.

Customer warning: Flyin' Miata is the exclusive US distributor for Miata V-Maxx suspension. Kits from elsewhere will not have a warranty nor will they have the correct spring rates. Buyer beware!

Pleasantly surprised
I had heard these would be uncomfortable to daily but after getting them on the car I am amazed how how awesome these feel. The increased cornering performace has me slightly afraid to push further considering Im much faster in the corners with absolutley no complaints from the car. I couldnt be happier with the level of customer service and the performance of this product especially considering the price range. People talk about bang for your buck but these are more like high explosives for pennies!

A value-oriented performance coilover.
The TL;DR: A good entry level performance coilover that requires a little help.

Firstly, I'm a huge suspension nerd. On my other vehicle, I measured motions ratios, calculated natural frequency, and ordered a very custom setup. Thankfully Miatas have been around a while and folks like Flyin' Miata have already figured out what rates work well. The 9K/6K rates (in metric) are a nice balance between predictable handling and a playful rear end. I also don't really know why'd you go softer than 9/6, as I find it to be pretty comfortable when valved correctly.

When I first installed these coilovers, the rebound felt good, but the compression felt like crap in the rear. I later found out that the issue was I was hitting bump stops. Even with recommended ride height per FM, the rear just had too much sag. At this point I opted to install 2" tophats in the rear, which avoid the bumpstop issue. The coils are worlds better now, but unfortunately sit incredibly low even with the helper spring almost fully compressed! Note that this issue is specific to the rears, and the fronts are totally fine.

The other thing I'd like to share is that I don't find the adjustability to really do much. There's minor difference in the clicks, but overall they are not very sensitive compared to other coilovers I've used. For instance, 3 of 30 clicks on my BC racing shocks means the difference between crazy oversteer and a balanced car.

Despite these minor complaints, the value is definitely here. The perfect spring rates, overall good dampening that's more track-oriented means a solid package for your NA/NB miata! Oh, and the folks at FM are awesome :)

Excellent product and support!
Love it!
I live in the Tampa area, so the roads are generally smooth, but any bumps that I do find are felt but by no means jarring. No bouncyness, and I haven't felt any bottoming out so far. The way the car performs during hard turns puts a big ol' grin on my face every time! I love how they handle any imperfections smoothly but then nearly eliminate any body roll when I'm feeling froggy. Would definitely recommend to any who ask, and the FM support was very nice to have when I hit a snag removing the stock suspension.
