NA/NB Stage 5 Big Mama Jama Brake Kit

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 - 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 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.

For those that need even more heat capacity and stopping power over our Stage 4 kit, the Stage 5 is 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. These calipers saves up to two pounds per corner.

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. 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. The rear calipers include a built-in parking brake, which takes off about 3 lbs of unsprung weight from each corner. Note that while this parking brake will hold the car on a very slight hill, it's not a strong parking brake - always leave your car in gear and point your wheels towards the curb. 

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.

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 2001and 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.

Please note that these are only available in red, the pictures showing black calipers are outdated. 

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:
