Now made of stainless steel!
Under hard braking, the firewall will actually deform, allowing the brake pedal, booster and master cylinder to move. This flex takes away some of your brake pedal stiffness and makes it more difficult to balance the car on the edge of lockup because there's essentially a big spring in the system. You'll find your braking will be more precise and will require less pedal travel.
This simple brace bolts into your Miata and keeps the master cylinder right where it's supposed to be. It's adjustable for a perfect fit. Exclusive to Flyin' Miata!
For left hand drive cars only! Fits 1990-05 Miatas except for cars with the big double-size brake booster (2001-02 without ABS, 2001-05 Sport non-Mazdaspeed with ABS). If your booster is 3" thick measured from the firewall, it will fit. 4" boosters will not. There may be interference with the factory NA airbox that will require modification.
Not compatible with factory shock tower braces, although it is compatible with all Flyin' Miata braces, past and present. Does not fit with our Randall Cowl Intake on the 1990-97 cars, but it does fit on the 1999-05. Also, you must have at least 1/4" of exposed threads above the nuts on your shock bolts.
1990-93 cars with the original front upper mounts cannot fit both this brace and our shock tower brace due to the length of the studs on the upper shock mounts. Also, 1990-91 cars without the rear mounting hole will require a hole to be drilled and some reshaping of the fender with a hammer.
