Flexing your muscles is cool, but flexing your firewall isn’t! You might underestimate your strength, but every time you press your Miata’s brake pedal you are slightly flexing the firewall where your brake master cylinder is bolted. The flex results in a mushier pedal feel and less precise braking action.
Installing the R Theory Brake Master Cylinder Brace prevents this flex. This results in a more confident pedal feel and more precise brake modulation; meaning you can brake on the limit much more easily.
The Master Cylinder Brace bolts to your strut tower studs and the nickel-plated stopper push up against the end of your master cylinder. The nickel plated stopper is adjustable in length to fit different master cylinders across the range of 1990-2005 Miata's
Designed for the NA/NB Miata chassis, years 1990-2005.
