NA/NB Miata Brake Master Cylinder Brace

When pushing the brake pedal, you only want one thing to move: the brake pads! However there is a lot of flex in other parts of the OEM Miata system; this includes items like the rubber brake lines but also the firewall itself. Below is a video showing just how much the master cylinder moves when the pedal is depressed hard. A master cylinder brace help reduce this excess movement and convert it back into braking power.  Product does not fit OEM NA airbox applications. Fits OEM NB applications. Might have to remove OEM tower brace if installed. Will not fit with OEM tower bracing.
