Thank you. You have rated this product.

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!

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.

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.

BRIAN'S APPLICATION NOTES:

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.  But, to save money Wilwood recycled parts from a front drive kit and we quickly discovered problems with some of the platform sharing parts used, including that track high temps resulted in the center aluminum hat having enough thermal expansion to contact the brake pad packing plates after about 50% wear of the pads.  Result included lots of extra noise and slow destruction of the aluminum hat finish and connection tabs to the rotor, etc.  What's the point of a big brake kit that cannot get seriously hot and still work?  Thus, we do NOT sell that Wilwood 12.88 branded kit and we do not recommend it, though we do offer their 12.19 inch kit because it doesn't have the issues of their 12.88 kit.  That makes the Goodwin Racing 12.88" kit the only track tested and rated kit of this size, including upgraded more stout brackets used in the lesser kits, more stout hats and hardware, lines that fit without extra connections that can leak, etc.  Bottom line is the highest quality and highest performance 12.88 kit on the market for the ND, track tested by our entire team and Grassroots MotorSports Magazine and proven....even with trap speeds obtained with turbo and supercharger on this chassis.

RYAN's ENGINEERING NOTES:

I'll point out another key difference that hasn't been touched on above: the attachment of the rotor to the hat. Wilwood's rotor-to-hat attachment has the bolts installed from the back and they thread in to the soft aluminum hat. If that sounds like a bad idea to you, you're right. Because it's a bad idea, they require that you use lock-tite on the bolts to ensure they don't back out of the aluminum threads. What you won't find out until down the road is that when it comes time to change your rotors things can get ugly. Sometimes things disassemble OK.. sometimes they don't. We have had several instances where the combination of loctite and heat seized the bolts in the aluminum hats, and at that point there is no choice but to get out the cutting tools and grind away on the bolts and hat to separate the rotor from the hat. The hats are trash and not re-usable at that point.

Our hats are designed to use a through-bolt connection. The bolts go in through the front of the hat and a serrated locking nut goes on the back. Follow the simple torque procedure noted in the installation instructions and you're set. No loc-tite needed. When it comes time to change out your rotor rings, nothing is seized and it's an easy job that can be done at home or even track-side.

REVIEWS

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.
