Mazda Miata MX-5 GWR ND 12.88" Front Big Brake Kit 2016-2024

MAXIMUM brake performance - better braking response, more thermal capacity, unsurpassed longevity, lower weight, cheaper replacement costs, better looks and MORE FUN.

RIGID and ultra light 4-piston caliper for improved braking response over the standard single piston OEM brake calipers, reduced unsprung mass, wider pad selection, better looks and MORE FUN.

BIG 12.88" rotors with lightweight aluminum hats that fill the 17" wheel beatifully. Despite almost 2" larger than factory rotors these come at lower weight!

YES, we know Wilwood has their own 12.88" kit for the ND. That kit is similar to some of our early prototypes we tested while developing our own kit, and we quickly discovered problems with some of the parts used there, so we do NOT sell that kit and we do not recommend it. The Goodwin Racing 12.88" kit addresses these issues and more and is the highest quality and highest performance kit on the market for the ND.

Balance Not all fancy red calipers are the same, our caliper piston sizing was chosen with great care to retain the superb braking balance.

Weight Big rotors need not add massive weight! Thanks to the carefully designed scalloped aluminum rotor hats used here, these 12.88" rotors come in a half pound LIGHTER than the stock rotors per side. Combined with the weight savings from the light aluminum calipers, this adds up to this kit shedding a total of 9.3 lbs for the 4 piston kit or 6.3 lbs for the 6 piston kit.

Rotors Our BBK uses large, slotted 12.88" Wilwood rotors for improved braking torque and TONS of thermal capacity. These rotors feature curved internal vanes and premium grade carbon iron for the highest cooling capacity and longevity possible. The lightweight aluminum hats have 12 mounting points for very even force distribution. The icing on this cake is that this rotor and hat assembly weighs in lighter than the factory 11" rotors!

GWR Exclusive Our kit uses our own brackets designed in-house, CNC machined from the highest grade aluminum with steel thread inserts. These brackets are designed for superior strength and rigidity and feature our signature hard anodizing.

Our stainless steel braided lines are included as standard and they are the most durable and heavy duty lines on the market, custom made for us and featuring DOT fittings. Made to fit (too many competitors use general purpose lines to save cost and include lots of extra connectors to 'make it work' with the unnecessary risk of fluid leaks).

Pads Upgrading your ND with to our Big Brake Kit gives you access to the wide and familiar selection of performance brake pads that we have decades of experience with! Replacement pad costs for these calipers are also far more affordable than for the factory calipers. Kit includes BP20 pads which are great for street/light performance use and match very well with factory pads in the rear. If you would like to swap to a different pad for more aggressive use, just shoot us an email!

Comprehensive kit includes: * DynaPro 4 or 6 piston calipers * BBK Mounting Brackets * Stainless Steel brake lines * All mounting hardware *12.88" Slotted rotors and hats * BP20 Street Performance Brake pads * Wilwood high-temp brake fluid

Fitment Notes YES, Fits under the factory 17" wheels! Also fits all aftermarket 17" wheels that we sell here. Pictures below show SIX Piston Version.

BRIAN'S APPLICATION NOTES: Had a three day event at Mazda Raceway Laguna Seca and fried the stock size rotors on the first day (had our caliper upgrade and our two-piece rotors in stock size for first day). Fortunately we had this setup on display, changed to this 12.88 setup and ran it hard for the rest of the weekend and loved the upgrade over stock size setup. This is the setup for ultimate confidence lap after lap after lap, allowing me to pass deep in the brake zones knowing I could stomp the brakes late in turn 2 and still neatly exit the turn. Braking confidence deep in the brake zones is a luxury, and an unfair advantage, and worth the cost! Dust Boots We occasionally get a call from someone asking if these calipers have dust boot seals because the factory calipers have them and so they assume this is a feature they need to be concerned about. Wilwood brake calipers, just like all racing brake calipers, do not use dust boots to seal the caliper pistons. This is intentional and done for several reasons, including the point that rubber dust boots can catch fire under extreme brake heat. The pistons fit tightly into the caliper so they seal without the need for rubber seals. In our decades of experience with thousands of Wilwood calipers this design has proven itself completely reliable. These calipers are suitable for road use in all climates and conditions as well as on the race track.
