    There are a bewildering array of brake upgrades for the Miata. We've tried to simplify things for you by only specifying the best components.

    Wilwood makes the calipers in these kits, but they are not Wilwood kits. This particular mix of components - especially the rear - are exclusive to Flyin' Miata. There may be less expensive options out there, but there are none better. And when it comes to brakes, you want the good stuff.

    All of our big brake kits use Wilwood Dynapro calipers up front. This caliper is stronger and stiffer than the older Dynalite found in many kits. The advantage is a firmer pedal and easier modulation with much better pedal feel - and of course, it means that more of your braking effort goes into braking instead of just deforming the caliper! We also supply our own custom stainless steel lines which have fewer failure points than the Wilwood lines often found elsewhere.

    The standard caliper is a 4 piston version, which is suitable for street use and most track drivers. For those that need even more heat capacity and stopping power, we offer a 6 piston upgrade. We use these on our V8-powered track cars and can attest to their great pedal feel. The 6 piston caliper even has staggered piston sizes for more even pad pressure and longer pad life. The pads are larger as well, which means more heat capacity.

    The piston sizes in the calipers have all been chosen for compatibility with the Miata's master cylinder. There's no need to change out your master cylinder. As an added bonus, pad changes are almost ridiculously easy on the four piston kit. There's no reason to run a compromise brake pad, just pop in your track pads when you put on your track wheels. The standard pad with the kit is the Wilwood BP-10, a street and autocross pad. Stage 1 kits use the BP-10 up front and a similar Porterfield R4S in the rear. You'll probably want more aggressive front pads such as our BP-20 or BP-40 for track use. We're unable to remove pads from the kit. 

    The calipers are wrapped around a 2-piece rotor specifically designed for this application. This rotor is unique to Flyin' Miata's kits, and is a slotted rotor made in the US from Wilwood's proprietary Spec 37 compound. This metal gives very long life as well as dimensional stability under rapid temperature changes. It's the best rotor we could find, so we made it standard on all our kits.

    In the rear, we have two options. The Stage 1 setup uses custom brackets of our own design to space the stock rear calipers outboard. They're designed to mount to the same machined surface as the stock caliper, not to an inconsistent cast surface like some others we've seen.

    Stage 2 is exclusive to Flyin' Miata and puts a light and stiff Wilwood caliper in place of the stock unit. This drops more than 3 lbs of unsprung weight from each corner, improves pedal feel and gives more braking power than the stock calipers. Now, we have to admit that the braking power from this Wilwood parking brake setup is not as strong as stock. We strongly recommend parking your car in gear, but it is legal for use in competition classes that require a parking brake. Stage 2 is only available in red - show off what you've got!

    The rear rotors are the same slotted one-piece parts used on those Sport brakes. Again, stainless brake lines are included as are high-performance brake pads.

    To ensure that you're using these brakes to their fullest potential, we also include an adjustable brake proportioning valve. This will let you dial in the perfect balance regardless of your car's setup. Only Flyin' Miata offers this option.

    Will they fit your wheels? Probably, if your wheels are 15" or larger, but you can make sure with our fitment template.

    Please make sure you select the correct rear kit for your car - match it to the calipers you already have on the car.
