The ultimate brake rotor upgrade for the 2009-2011 Nissan GT-R has been the STILLEN/ AP Racing CCM rotors. The CCM's are 400mm x 34 mm, and weigh about 38 lbs less than the factory rotors. For 2009-2011 the standard front brake rotors on the GT-R were 380 mm x 34mm. On the 2012 Nissan increased the diameter to 390 mm but went thinner with a 32.4 mm thickness.

In conjunction with DSPORT Magazine, we are doing a trial fit on a set of CCM's for a 2012 Nissan GTR. I will keep everyone updated, and get an ETA as soon as I can get one. Some more information on the CCM's is below. Until then a couple quick teaser shots.

CCM Brake Rotor Weight
Front rotors (assembled with aluminum hat and hardware): 14.2 lbs. ea.

Rear rotors (assembled with iron hat and hardware): 17.5 lbs. ea.

Front caliper locater: 0.3 lbs. ea.

Rear caliper locater: 0.2 lbs. ea.

New forum setup is fighting me on this. Third times a charm?

Some information from Chris Bernal.
There is a lot of confusion out there when people hear "carbon brakes". In racing, carbon-carbon (C-C) is used wherever the rules allow it. For high-performance road vehicles, carbon-ceramic matrix (CCM) is the rotor of choice. Carbon-carbon brake systems consume both the rotor and the pads, where CCM brakes are designed to consume only the pad.

There are a few different ways to make CCM rotors. The ones on the Scuderia you mention are made from three pieces, a chopper-gun-like core and two face plies -- and only those face plies are siliconized into carbon-ceramic. The core remains C-C. So far, this style of construction is more delicate and less user-friendly than a full 3D CCM, like those on the STILLEN GT-R upgrade. The 3D version takes longer to make and requires more energy, so they end up being more expensive.

The enemy of CCM brakes is not wear -- they are very, very hard (approaching diamond hard!). The real issue is oxidation. As long as rotor temps are kept below 750°C / 1400°F, they could possibly last the life of the car or even longer. If run for extended periods of time over that temperature, oxidation will start to convert the carbon molecules to carbon dioxide, which just floats away. So it pays to keep track of rotor temps, which is why we apply paint temps at STILLEN before we assemble them to the hats. Cooling kits are a great idea for track use. Keep in mind that the pads will also run hotter as the rotor has less mass to absorb braking energy than iron discs, so the CCM discs will heat up everything around them a bit more.

Now here is another interesting point: If you were to oxidize those Scuderia CCM rotors (or the ones on any Ferrari, Lamborghini, Porsche, Aston Martin, Audi, ZR-1 Corvette, etc.) you get to throw them away after they lose a prescribed amount of mass. With the Stillen GT-R system, surface oxidation can be ground off to where the rotor looks like new again. This can only be done with a full 3D CCM rotor, not the 3-piece laminated type like on the other cars mentioned above as you would grind right through the thin face plies!

If we chose to go with the 3-ply route instead of 3D, we could probably lower the price a couple grand -- and then have to deal with the occasional dissatisfied customer who would have to replace a front pair when they were excessively oxidized or if damaged by putting wheels back on the car. In the service manual for the ZR-1, the service tech is required to place a foam ring around the rotor before removing a wheel. If not, the dealership gets to pay for a new rotor if he chips it. While I certainly don't recommend pounding a wheel against the STILLEN/AP Racing CCM rotors, we are much less concerned about careful, routine service creating such a problem.

Even though carbon-carbon has been around since the 70's (I started working with C-C in 1990), the more recent availability of CCM to the general public will continue to cause confusion until we get further down the road. They are not the same as iron in any capacity other than they are roughly the same shape. We can't expect that after 100 years of iron drums and discs that CCM technology will be completely understood by the masses for quite some time. Then add the fact that they are still changing as companies continue to look for ways to reduce the manufacturing costs.

That or this:



Heh, just pokin' fun. Hope it fits, I had no idea that the rotors were thinner for 2012.

Sorry for going OT but are you serious a Ducatti 1198, S no less, is only 16k in the US?????!!!!!!

Holy crap, prices for stuff in the US is just so much better than anywhere else in the world.....

Back to the brakes, awesome, but out of my league unfortunately.

Sorry, my post was a little misleading. The standard 1198 is $16k, the 'S' is more.

They're not cheap but the rotors should basically last forever...
And weigh about 38 lbs less than the standard 380 mm rotors. The less weight the car has to carry around, the better. Less to accelerate, brake, and try and get to change direction.

38 lbs here, 25 lbs there, 20 lbs there. Pretty soon you have lost 150-200 lbs. Owners are always looking for more speed.

Even better than less weight for the car to carry around is less unsprung weight to tax the suspensionn.

Less unspung weight = better handling.

38lbs is being removed from the suspension of our cars is no joke! Can't wait to see how this turns out on the 2012.

Couple that with some non- run flats, and you can pull about 50 lbs of unsprung weight out, even on the 20" wheels.

R888 285 = 32lbs
R888 315 = 32.9lbs

2009-2011
S600 255 = 37lbs
S600 285 = 40lbs

2012
SMaxx600 255 = 36lbs
SMaxx600 285 = 39lbs

I can ship a set to you today. APCC1100.

Dsport has had a set of CCM's for a 2012 on their GT-R since before SEMA.

This is from the test fit. The last time the car was here, I don't think I took any photos of them fully installed.

So DSport caved in and bought a GT-R. Thought they said only if one was equipped with a manual tranny. Guess they couldn't stand sitting and watching us have all the fun.

My ears just perk up at that. How much weight did they lose? Care to say? The they stuff they remove is it all good for a road car?

The numbers are all part of a story they are working on. The car was at SEMA, but I can't remember the exact numbers. It lost a good amount of weight. If you go to their Facebook page, you can see some information.

Thanks Sean. Will check that page.
