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.
To start, here's a specific list of what's included. There are lots more details below the list.
- Front big brake kit with brackets, stainless steel brake lines, Wilwood calipers, and two-piece Wilwood Spec-37 rotors
- Rear Porterfield R4-S pads and stainless steel brake lines for your stock calipers
- Rear 11" single-piece rotors (choose plain or slotted)
- If you have a non-Sport ('94-'01 and some '02 and '03) Miata, we include brackets to allow you to use 11" rear rotors with your stock calipers. Note that we don't offer this kit for '90-'93 Miatas, for those cars we recommend our Stage 4 or 5 Big Brake Kits.
- Optionally, a brake proportioning valve (read more below).
All of our big brake kits use Wilwood calipers upfront, this one uses red Dynapro calipers specifically. 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. 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 front pad with the kit is the Wilwood BP-10, which is a street and autocross pad. The rear pad is a similar Porterfield R4S. 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 front 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.
In the front, you'll save up to five pounds (Sport brakes to four-piston BBK) per corner. If you start with smaller rotors the weight savings will still be significant, but not quite as much.
For 1990-1993 and 1994-2001 (non-Sport), we use 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. If you have a 2001-2005 Sport, you already have 11" rotors, so you don't need the custom brackets. You get to save some money, but still get the better pads and lines.
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 (on non-friction surfaces) 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 template:
The rear brake setup will fit under every 15" wheel we've come across.
Please make sure you select the correct rear kit for your car - match it to the calipers you already have on the car.
