The ultimate autocross brake package. Four-piston calipers all around, an SCCA legal parking brake and clearance for 13" wheels.

Made in the USA

Exclusive to Flyin' Miata



A great street or autocross package. Only Flyin' Miata offers a caliper upgrade that will fit under 13" wheels or stock ones - and only Flyin' Miata offers a rear caliper upgrade that retains the parking brake. This is what Keith runs on his street Miata, and he loves it.

Up front, we replaced the stock single-piston iron caliper with a light and stiff aluminum four-piston Powerlite caliper. That's responsible for a 4 lb weight loss per side. It's compact enough to fit around the small Miata discs, but is nice and stiff and gives even pressure across the 5 square inch pad. Since the 1.38" pistons are properly sized, the stock pedal feel will not change. Porterfield, Hawk, Carbotech, Performance Friction and Wilwood all offer a full range of pads to choose from.

In the rear, we install a version of the same caliper with 1" pistons. There's a 3 lb weight loss per side here, for a total weight loss of 14 lbs of unsprung weight. This rear setup does generate more braking power than stock, so you will see a shift in balance towards the rear.

Weight note: The drop in weight quoted here assumes that you're sticking with the same diameter rotors that you currently have. If you go up to a larger rotor size, the weight savings won't be as significant due to the increased rotor mass.

What really makes the caliper special are the custom alterations that allow it to work with a handbrake. This makes it eligible for many race classes that require a functional parking brake. That's right, it's SCCA legal.

Now, it's not a strong parking brake, nowhere near as strong as stock. It is not strong enough for drifting. But it will hold the car on a moderate grade when properly adjusted. We do recommend leaving the car in gear as well if you're going to be parking on a steep slope. That's pretty much anywhere in San Francisco.

The kit includes a brake proportioning valve so you can dial in the perfect balance for your car. 2001-05 ABS cars use electronic brake distribution, so you'll want to delete that option.

We ship the kit with Wilwood BP-20X compound pads in the front, which are a good street/autocross choice and will even stand up to track use. The rears are a BP-10.

This version is designed to use either the stock 10" 1994-02 or stock 11" 2001-05 Sport rotor size (rotors not included). If you have a car with different rotor sizes, all you'll need are the correct rotors to install this on your car. If you want to mix and match rotor sizes - say, 10" front and 11" rear - go for it.

This kit will fit under a wide variety of wheels. The version without a parking brake will fit all the stock wheels from 1994 on, but the parking brake version means you can't use factory 14" wheels. The 11" setup tends to fit a few more wheels due to the placement of the caliper. To check on your car, use our templates.

Color note: Wilwood has transitioned from Type II to Type III anodizing. The new process is harder and more dense than Type II. The old anodizing could also change color under very hot temperatures, which is not a problem with the new process as no dyes are involved. Unfortunately, the lack of dye means it's a grey color instead of black - please see pictures for details.

The kit includes:
Wilwood Powerlite 4-piston calipers and Wilwood BP-20X pads front
Wilwood Powerlite 4-piston calipers and Wilwood BP-10 pads rear
stainless braided lines front and rear
FM proportioning valve kit (if selected)
parking brake cables (if selected)

Please note that both the front and rear brake lines are unique to these calipers. If you currently have stainless lines for stock calipers, they will not work.

This is an excellent kit that is a substantial upgrade. My combination is the 4 piston front and rear using 2002 Sport rotors with and the emergency brake feature. My Miata brakes was okay, these are impressive. This kit will require you to relearn your foot because they can stop hard.

Some install notes: I'd urge FM to look through and update the install PDF, while I figured it out it was a touch confusing. More pictures for us simple monkeys.

Also you may need to arch the spring clips to account for pad rattle, a easy fix.

Last but not least, installing the emergency brake cable was a slice of the warm afterlife unto itself using a creeper, strongly recommend you find a lift to get access for this portion of the install if getting the emergency brake option.

Just at a month in, very happy with the performance of these brakes and can recommend them.

Awesome kit, adds so much to the car
I got this kit for my 2003, four piston powerlites on all four corners, parking brake and adjustable proportioning valve which will run you exactly $1,200. I'm still running stock sized tires so maximum braking can't be increased but everything else is much much better. Initial bite is amazing once you get some heat in them, brake pressure throughout feels so much better so you do stop quicker until you reach that lock up point. This encourages speeding up just so you can slam on them every once in awhile to feel how fast you can get close to that point and hold it.

The adjustable proportioning valve is, in my opinion, the centerpiece to this kit. Lift up the hood and with the twist of a knob you can set up your brakes any way you want in seconds, daily driving, track driving, drifting, it's a lot of fun to play around with.

The E-brake is the only reason this review isn't four stars, they do warn you about it but it really does suck. With it adjusted as tight as I dare go it still won't hold the car on its own on any grade above about 3 degrees. My recommendation is make this kit cost you $1,220 and buy some chalks to throw in the trunk, and always always always park in gear.

As for installation, it'll take a day at least even with some help from a friend, the dust guards in front took some slight trimming with tin snips but other than that it's completely bolt on, quick and easy. The parking brake takes some wrestling to get off the car and to get the new one on but that's the only true challenge. Make sure to use thread sealant where the lines attach to the calipers and for the proportioning valve or you will have leaks everywhere!

All in all, amazing kit, would absolutely recommend!
