Description

Please note that this design won't work with stock NA air boxes. It works fine on NAs that don't have a stock air box (assuming your intake doesn't overlap the shock tower), and it works fine on NBs with or without the stock air box. We're working on an updated design to address this, if you have an NA with a stock air box please stay tuned. 
Some say that you don't need a shock tower brace on a Miata because it's not a strut suspension. While it's true that the shock towers don't see any cornering loads, they do carry all the vertical loads in the car - and the engine bay is a big open hole. A shock tower brace "closes the box" on that big hole and makes the whole front end more rigid - improving the quality of your steering and cutting down on the shudder through the chassis when you hit a pothole or racetrack kerb. It will also help with the 63 mph shimmy. Mazda started adding shock tower braces to the sportiest Miatas in 1999 and still uses them today.

Plus they look great.

What makes ours better? It's missing the "pivot points" that many cheap braces have where the bar meets the towers, making it as rigid as possible. The cross bar is as close to straight as we could make it for the same reason. Without this sort of design, the brace wouldn't actually do anything. It's made of stainless steel so there's no powdercoat to chip and no chance of rust. Compatible with our master cylinder brace so you can also get a great feeling brake pedal. Fits with stock Miata engines and LS engines (without intake manifold insulation or coil covers) as well as our turbo systems. Not compatible with Honda K engines, they're too tall.
Note that while this will physically fit a Mazdaspeed Miata, it doesn't have provisions for the catch can (air/oil separator) or its plumbing, so you'll have to do some problem-solving there. 

Quick installation. Works with Canadian NA washer bottles - it's close and the installation is slightly more complicated, but once in it all fits great.

Beautiful Product - Fitment Measurements Would Help

First off, this is a gorgeous product and fits great. Very strong, beautiful welds, pretty satin finish. Quality is extremely high across the board. I have the FM brake master cylinder brace installed as well and both fit together fine (my suspensionis Ohlins R&T and the studs are plenty long to accommodate both - worth checking in advance if your studs will be long enough as well). One thing that would be helpful: if FM could add to the instructions some precise (mm) measurements of clearance from the highest point (on 1.6, 1.8 and 1.8vvt) to the bottom of the bar. This would help for different applications where clearance isn't immediately obvious (for example, I have a custom AN-line catch can setup that doesn't clear). This is not FM's fault of course - it would just help us make a good decision on whether to buy.

With engine mounts that can sag and aftermarket mounts that could move the engine higher, the dimensions we would give may or may not match any given car. Hopefully, since you have a custom setup to start off with, things can be tweaked. As always, feel free to reach out to our customer support department for opinions and suggestions ahead of any purchase. Or after the fact, of course. Thanks for the review, we're glad you like the product!

Koni Adjustment Knob Conflict

Beautiful piece, but doesn't seem to work with the (NB) white Koni adjustment knob. If FM could make a 3D printed knob for the suspension adjustment that's both grippy and small enough to fit under the brace uprights (maybe with a line or something to keep track of the amount turned), I'd be interested.
