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 6-piston calliper for improved braking response over the standard single piston OEM brake callipers, reduced unsprung mass, wider pad selection, better looks and MORE FUN.

BIG 12.88" rotors with lightweight aluminium hats that fill the 17" wheel beautifully. 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.

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

Big rotors need not add massive weight! Thanks to the carefully designed scalloped aluminium rotor hats used here, these 12.88" rotors are over 200g LIGHTER than the stock rotors per side. Combined with the weight savings from the light aluminium callipers, this adds up to this kit shedding almost 3kg for the 6 piston kit.

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 aluminium 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 aluminium with steel thread inserts. These brackets are designed for superior strength and rigidity and feature our signature hard anodising.

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).

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 callipers are also far more affordable than for the factory callipers. 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 6 piston callipers
* 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

Brian GoodwinBRIAN'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 callipers 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 callipers have dust boot seals because the factory callipers have them and so they assume this is a feature they need to be concerned about. Wilwood brake callipers, just like all racing brake callipers, do not use dust boots to seal the calliper 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 calliper so they seal without the need for rubber seals. In our decades of experience with thousands of Wilwood callipers this design has proven itself completely reliable. These callipers are suitable for road use in all climates and conditions as well as on the race track.
