The biggest brakes. If you want to stop the fastest ND Miata in the world, it's what you use. Six pistons and nearly 13" of rotor diameter.

Made in the USA

Exclusive to Flyin' Miata



When we need enough brake for our 500 hp V8 cars, this is what we use. Car and Driver tested a stopping distance of 148 feet from 70 mph, which is 10' shorter than the stock car despite the extra 260 lbs of the V8 test car. On track, they hold up to hard repeated use even with that massive engine.

The pedal feel and balance is excellent due to the stiff Dynapro calipers with properly sized pistons. Slotted two-piece GT-48 12.88" rotors use superior  metallurgy with directional vanes. This metal gives very long life as well as dimensional stability under rapid temperature changes. We include our own one-piece lines to avoid multiple adapters.

Available as a front-only kit or as a Stage 2 with our exclusive four piston rear upgrade. Due to these upgrades, this kit is only available from Flyin' Miata.

Stage 1 includes:

Dynapro 6A 6-piston calipers (red or black)
BP-10 pads for front
GT-48 slotted two-piece 12.88" rotors
FM braided steel brake lines for front
All hardware required for installation - even a hose to bleed the brakes

Stage 2 includes everything from Stage 1 and adds:
Powerlite 4-piston calipers (red)
BP-10 pads for rear
FM braided lines in the rear.
NOT INCLUDED: rear rotors. You can reuse your existing ones or pick up some new slotted ones.

Stage 2 is only available in red at this time.

Will they fit your wheels? These brakes (front and rear) will fit under stock 17" wheels without the need for a wheel spacer. We have not yet tested them with factory 16" wheels. We do recommend you check against your own, however. Use these handy templates to be sure:

Despite some unsubstantiated claims found on sites trying to sell more expensive kits, this is a solidly engineered setup that was put together by the experts at Wilwood and tested on the fastest ND Miata in existence both on the street and on the track. Don't be scared off by fear tactics!
