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 these are not Wilwood kits. This particular mix of components - especially the rear - is 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 upfront, this kit uses the four-piston version, which saves up to 5 lbs per corner. This caliper is stronger and stiffer than the older Dynalite found in many kits. The advantage is a firmer pedal and easier modulation with a 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 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, with an  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 a 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.

The rear setup is exclusive to Flyin' Miata and puts a light and stiff Wilwood caliper in place of the stock unit. In addition to sex appeal, swapping the stock (flexy!) rear calipers for the stiff Powerlites makes a big difference to the stiffness of the overall system, improving pedal feel and your ability to precisely modulate the braking even more than the front-only kit. Plus, it drops about 3 lbs per corner!

For the rear rotors, you have your choice between StopTech high-performance slotted rotors or Centric premium plain rotors, both of which won't rust and are made to tighter tolerances than others. 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 offer an adjustable brake proportioning valve, which is strongly recommended for cars that don't have Sport brakes (optional on 2001 and 2002, standard on 2003-2005) AND ABS. If you have Sport brakes without ABS, or ABS without Sport brakes, (or neither), the adjustable proportioning valve kit will decrease your stopping distance (when properly adjusted) by letting 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 don't assume - unless you know for sure, please check with our templates:

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