We know that Miata suspension works best when you give it room to move. Unfortunately, lowering the ride height by installing shorter springs means you lose some of your crucial compression travel. This means more time on the bumpstops, a rougher ride and poor traction - not to mention unhappy passengers and drivers. The problem is particularly bad in the rear.

That's why we developed these rear mounts. They move the upper shock mounting point up, adding 33 mm (about 1.25") of travel at the wheel. However, the ride height is not affected. These are the only mounts on the market that will add compression travel without affecting anything else. And yes, they'll give significantly more travel than a set of NB upper mounts.

For longevity, the mounts are milled from aluminum billets and anodized. A teflon-lined, stainless steel spherical bearing locates the top of the shock. This bearing (sometimes incorrectly referred to as a "pillowball") won't increase harshness at all, but can transmit a bit more noise from inside the shock. This will usually be just a little squishing noise on big suspension movements, such as driving into a driveway. It's kind of fun really. The bearings are carefully specified for long, long life and zero maintenance.

Bumpstops are NOT included. We include bumpstops with our shocks and our Stage 1.5 and 2.5 kits that use these mounts. These mounts are not compatible with stock bumpstops, so if you have not already upgraded then you will need to do so.

These bolt right in place of stock mounts and are compatible with 2.5" coilover springs (such as the Ground Control) as well as the stock sizes. They will not work with the Koni complete coilover setup due to a slightly larger spring diameter, however.

Not for use in conjunction with both the Koni Sport (yellow) shocks and the previous design FM springs, as they can cause coil bind problems. You want the current design, which is marked FMS9097REARFMMOUNT.

Sold in pairs. Not recommended for use on the front. Why not? Because if you increase the front suspension travel too much, you'll simply put your wheels into the fenders. We do recommend a pair of our bumpstops for the fronts. These upper mounts are intended for suspension setups that utilize stock or near-stock length shock bodies with lowering springs - full "coilover" kits like our V-Maxx and FOX suspension setups with shorter shock bodies and adjustable spring perches are not an ideal match with these mounts as you're likely to end up with too much compression travel which equals tires rubbing the inside of the fenders. Will not fit an NB chassis.

Available to fit all Miata shocks other than the AFCOs. Please specify shaft size when ordering. If your shock is not on this list, please check the diameter of the shaft. If you did not have to drill out the hole in your stock perches, it's 10 mm.
10 mm: fits KYB AGX, KYB GR2, Tokico Illumina, Koni STR-T (orange), Tokico HP and stock shocks.
12 mm: fits Koni Sport (yellow) shocks.
9/16": fits Advance Design shocks.

If you're not 100% sure of your shock shaft diameter, please measure before you order these! We've heard that some shocks from certain suppliers don't always match the shaft diameters above.

Shock Mount
These do not pair well with 2.5 springs right out of the box, you will need some form of spring isolator/locator to center the spring on the shock mount. Other than that the quality is top notch as would be expected from FM products.

Note from FM: you will need a spring locator when trying to use 2.5" springs with any mount designed for standard 4" springs. We include locators with our coilovers when applicable, and Ground Control does the same.

You need this if you're a LowLife like me.
Installed these with FM Springs, Fm Bump Stops, and Bilstein HD Shocks. Replaced Koni Lowering Springs. It was nothing short of transformation. Before this install I had grip issues in the back with a stock motor. Now I have an FM Turbo installed and the rear tires slip LESS than they did before.

No More Endos
I installed these last night on my 90 Miata. I run a stock powerplant, stock viscous diff, Tanabe lowering springs, stock shocks, stock sway bars, Advanti Storm S1's with super cheap rubber, front Good-win racing shock tower brace, lower arm braces front and rear, and a Cobalt rear shock tower brace. These top hats COMPLETELY changed my mindset on taking my car for a drive. I WAS embarrassed and apologetic when taking people for rides in my car BEFORE. It WAS a drift machine and an endo mobile because I HAD about an inch and a half of rear suspension travel (don't hire a maintenance mechanic for aftermarket work). NOW, after removing a bunch of crap left on my shocks and installing these top hats and included bump stops I am blazing over pot holes, big bumps, and dips yet my keister hasn't left the seat nor have I bottomed out, despite my efforts. Drifting takes a lot more coaxing now but the G force factor is stupid, even with cheap rubber. Rating out 5 = +2.5 Rear Grip, +5 Comfort, -2.5 Drift +1 Steady Understeer, +2 Transitional Understeer. Going to install longer front bump stops to fix the Understeer.

These mounts are awesome, I got these with the 2.5 kit and even though my spring and dampening rates are significantly higher I have no complaints at all about ride quality. These really go a long way in helping the back keep from bottoming out. Stripped the threads right out of the stud on one mount. This is not covered under warranty (user error) so take care not to overtorque (last time I trust a harbor freight torque stick).

Great addition to suspension
Relatively easy to install and when combined with Flyn Miata Springs give a very solid non jarring ride. The extra shock travel makes a significant difference in comfort and control.

If you lower your car its a must have. Awesome quality
not cheap, but the quality is perfect, but first of all the effekt is noticeable. much more travel and smoother ride. The inner hole may be a bit bigger for thicker shocks and the shock-covers. But Overall i never want miss it.
