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 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.
Note that this is a front-only kit, and you may end up with too much front proportioning for effective stopping distances. We recommend a four wheel kit mated with a proportioning valve for maximum effectiveness.
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.
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.
Will they fit your wheels? Probably, if your wheels are 15" or larger, but you can make sure with our fitment template.
