FM NA/NB shock tower brace

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. 

The original version of this bar wouldn't clear stock NA air boxes, the current version clears those just fine.
