Godzilla Unleashed : Nissan GT-R for Australia

2012 Australian Market Nissan GT-R

The Australians have had Nissan Skylines/GT-R's sold there off an on since the 1960's. R32 GT-R's were officially sold in limited numbers, and raced in Australia in the early 90's. They did so well in racing that the car was eventually banned, with the crowd at Bathurst called a pack of arseholes by Jim Richards.  Cars in Australia are right hand drive, and the government there has a program which allows for certain type importation. So over the years, even when the GT-R was not imported by Nissan, individuals imported their own.  In the limited market (22 million people) of Australia, the Nissan GT-R is a popular car. 

The 2012 Nissan GT-R in Australia comes in at $170,800 AUD ($176,914 at current rates). The 404 kw(541 horsepower) specs line up closest to what we call the 2013 Nissan GT-R in the US.  Australians get the privilege of paying about 70% more for the same car than the US market.  Since they started taking pre-orders in October 2008, Nissan Australia has sold about 420 cars. Closest I can find to official sales numbers. 

The price has gone up $2000 for the 2012 model-year GT-R, so it starts at $170,800, still half the price of rivals with this performance potential.
The outgoing R35 incarnation of the GT-R has more than 420 examples on Australian roads - and more than 20,000 have sold worldwide since the model's launch in late 2007.
** VERDICT Nissan's supercar remains the best value performance machine around. Something of German or Italian heritage that can keep up with this Japanese mutant would be more than twice the price.
Even at $170,800 its a good value for the money in Australia compared to offerings from Ferrari or Porsche.

AMS Alpha Omega: 8.62 Official Video

Getting loose

It seems like its AMS after AMS today. They did a lot in the last few weeks with their 1600 horsepower Nissan GT-R. A great group of guys and an asset to the GT-R community. Check out the video below.


With the tracks closed in the Chicagoland area until late April, our annual trip down to the TX2K GT-R Nationals events in March offer us the first opportunity to test new vehicles that we've been working on throughout the winter months. This year, initial testing of the AMS Alpha Omega at the TX2K12 was a definitive success. This was the first time the Omega has ever made an appearance at the drag strip and much was accomplished and learned.


SATURDAY

On Saturday, the Alpha Omega began on a low boost setting around 24lbs. After that, boost was increased to around 35lbs max and our first clean pass was just short of the record ET by three thousandths of a second (8.79@169mph)! At the end of that pass, one of the intercooler pipes popped, shooting downward at the under tray. This, along with the deployment of the parachute (causing the GT-R to dip) was believed the cause of the lip ripping off the vehicle as seen in the video. Ivan Phipps, our mechanic and driver of the Alpha Omega worked quickly to replace the lip, under tray and bumper so that we could make another pass.

The last pass of the day was made just before the lanes closed. Ivan launched hard with a 1.47 60ft, and began losing traction badly a little farther out. Most people at the line thought he would abort with the lanes being so narrow, but he stayed in it and straightened out to break the ¼ mile record with an 8.63@172.15mph pass! Again, the lip tore away from the bumper and the cause was finally attributed to the high speed and larger intercooler interfering with the lip support brackets. Ivan already had a solution in mind, but without another front end, the crew would have to pack it up and head home.

With the car breaking loose on the last past, the AMS crew felt the Alpha Omega had more left to accomplish on Sunday so the crew worked hard to source a donor GT-R for some parts. That evening, our sales manager was able to source a front end from NAGTROC forum friend two hours away and then found that Hennessey had an extra bumper and lip in storage that they were also willing to offer.


SUNDAY

Ivan began early in the morning to repair the front end and reinforce the lip with a set of modified brackets. The preparation was intense yet efficient, and the Alpha Omega made its first pass of the day with an 8.62@173.81mph -- breaking the record it had achieved the day prior off a slower 1.53 60 ft.

We attempted to run one more pass with the boost turned up past 35lbs, but the track offered very limited traction and Ivan aborted the final pass. Overall, the car ran strong all weekend long and was ready to take on the Texas Mile the following weekend. BE SURE TO SUBSCRIBE TO OUR YOUTUBE CHANNEL. The Texas Mile video is one you will not want to miss!

AMS would like to sincerely thank Tim Sanders, Hennessey Performance and "Wreckless" (nagtroc.org member). Without their help, generosity and support, this achievement would not have been possible.

Special thanks to Dodson, Exedy, Sheptrans and Driveshaft Shop for their support of the Alpha Omega project as well. 

Race Car Heaven with AMS World Challenge GT-R


AMS Performance from Chicago built a World Challenge spec Nissan GT-R for a customer a couple years ago. They did some great work with the car, but it was never raced in the series.

Recently they had a chance to take the car to the track in Florida. They were on track with everything from F1 cars to ALMS Audis, and vintage Porsches. Here are just a few pics, head over to the NAGTROC forum for all the pictures. I love old race cars.


Targa 66 is a really cool event that brings together a very eclectic group of race cars. From retired Le-mans and F1 cars down to our own GT-R World challenge Track car we built for our customer. We even had a full track built EVO X we did on track. The GT-R did phenomenally well even against some open wheel cars. Overall it was a fun problem free day for all.

2013 Nissan GT-R License Plate Bracket, Exhaust, Sway Bars, Brakes, and Skidplate

2013 Nissan GT-R Super Silver Black Edition



If you own a 2013 Nissan GT-R, and are looking for some parts to upgrade the performance, looks, and braking, STILLEN has a number of parts available. Everything from the Carbon Ceramic Brake rotor set, to a no drill license plate bracket.


Fitted to a 2009 GT-R, also fits 2013
More than 1/2 the US has requirements to place a front and rear license plate on your vehicle. For some cars, like the Nissan GT-R, that means drilling holes into your front bumper. Many owners want to comply with the law, but don't like the conventional mounting method.


STILLEN has been producing tow hook license plate brackets for several years now. The tow hook is located in the front bumper area, and allows for easy removal in case you have to use the tow hook.

OEM 2009 Midpipe and 2012 Midpipe







The Nissan GT-R is a quiet car, even with 545 horsepower. It has two turbos, followed by two catalytic converters in the downpipes, then the midpipe has two catalytic converters, and a resonator in it. From the midpipe the exhaust travels to the back of the car, where there are two mufflers that lead to the four exhaust tips.

Top Gear - Stigs Nissan GTR Lap Cockpit View


This is a great view of the Stig from Top Gear in the Nissan GT-R during one of the timed laps. Anyone think that the Nissan GT-R drives itself? All computers? I think this is an old video, it says the car did a 1:19.7 in the video below. The 2012 GT-R is faster, a 1:17.8, good enough for #9 on the Power Board.

The Power Board

  1. 1:15.1 – Ariel Atom V8 500
  2. 1:16.2 – McLaren MP4-12C

2013 Nissan GT-R Black Edition : Motor Trend Long Term

The Stormtrooper look. White. Black wheels, carbon fiber wing


The magazine guys have a great job at times. Nissan loaned Motor Trend a 2013 Nissan GT-R Black Edition for a year, long term test.  Ed Loh tells the story of how Motor Trend got a second long term Nissan GT-R. Lots of YouTube videos, and some great print stories.

So, what are we going to do with a stronger, yet smoother Godzilla on its second go 'round? Same thing we did the first time: match it up against everything we can get our hands on to generate a zillion more video and page views. On its off days? Well, I like to think that this our victory lap with the GT-R, so it will spend time with each and every staffer -- like Lord Stanley's Cup. You'd better believe we're going to enjoy ourselves all over again.
Black Edition red trimmed Recaro seats

I don't think that most people realize how staggeringly fast the stock Nissan GT-R actually is. Super car quick for 1/2 the money. You don't have the look that most of the supercar buyers desire, but as a fast daily driveable street car its not too bad. 

0-60mph: 2.8s
1/4m: 11.1 @ 124.8mph
Lateral acceleration: 1.03g

MotoIQ: Helping Fast GT-R's Break Records

Revenge of the Nerd - The Consultant, Helping Fast GT-R's go Even Faster!


Mike Kojima from MotoIQ accompanied SP Engineering, Greddy, and Hing to the Las Vegas Motor Speedway, as part of the Nerd Alliance to help them with suspension setup. If you can make a car go fast, Mike can help you make it go faster. Mike has helped me in years past with some other GT-R's, and see's and understands suspension more than most of us ever will. What I noticed in the videos, from the two 8 second cars of this March, were how different they looked going down the strip.  The AMS car went quicker and faster eventually, but on a few passes it looked very out of shape.  60 foot time is very important in quarter mile ET's. The old rule of thumb is about 0.2 seconds for every 0.1 of 60 foot time.  While a 1.4 60 foot time is good for a all wheel drive R35 GT-R, some drag cars go deep into the 1.2 second range on an 8 second pass.

A couple of weeks ago, I got a call from the folks at Greddy Performance Products and KW Suspension to help with an effort to break the 1/4 mile record for a street driven full body R35 Nissan GT-R.
My part in the mission was to help pare down the 60 foot times and I gladly accepted the challenge representing KW Suspension.  I would be working with Chris Marion, who helps me in Formula D.  Chris and I work together quite a bit and I really enjoy working with him and KW.
The first 8 second time slip for the car. Notice the notes
SPL Parts provided adjustable links for camber and rear toe.  SPL bearings also replaced the stock rubber parts in the spindles.  Getting rid of the rubber will help reduce flex and wheel hop that drag GT-R's experience.  Before we got to the track, the crew set the alignment to our specs so all we had to do was turn knobs!

Head over to the MotoIQ article for an in depth analysis of the then record breaking 8 second passes.

CRP Racing Nissan GT-R World Challenge Weekend

CRP Racing/Hawk Performance Nissan GT-R in GT class
GTS class 370Z
The first World Challenge race of 2012 kicked off at the Grand Prix of St. Petersburg.  This would be the first event for the Hawk Performance/ CRP Racing Nissan GT-R. The car has been converted to rear wheel drive and runs a Hewland transaxle from early reports.
Mike Skeen was going to drive the #2 Nissan GT-R, with Jason Daskalos in the #12 GT-R, however only the #12 car made the event. Mike Skeen drove last years Corvette to the pole postion in qualifying with a 1:14.700, the GT-R qualified #14 with a 1:20.517.
Cadillac CTS-V Coupe. Porsche 911 GT3

Mike Skeen giving a tech talk behind the GT-R
Before the first race started, Skeen was out with a driveline/differential failure in the Corvette. This left the pole position open. The all wheel drive Volvo of Alex Figge grabbed the top spot from 5th by the first turn. Daskalos in the Nissan GT-R made it 11 laps before a fire put the car out for the race, and the weekend. Lawson Aschenbach in the Porsche won the first event but was penalized for passing during a local yellow, putting Johnny O'Connell in the Cadillac into 1st. The second race on Sunday, saw the Vette out again with driveline trouble, and Lawson Aschenbach taking the win. Head over to the World Challenge website for the full results for the weekend. Lots of good battles in GT, GTS, and TC, even over the many cautions that mar a street course like St. Petersburg. Next race is Long Beach 4/13/12.
Nissan GT-R had a fire during the first race, and did not compete in the 2nd race.

Two 8 Second Nissan GT-R's: A Comparison

March 16-18th, 2012, two Nissan GT-R's went deep into the 8 second range in the quarter mile. One car, the AMS Alpha 12 GT-R, had held the record with a 8.97@169 mph quarter mile pass since July 2011.  On Friday at a private track rental in Las Vegas, the SP Engineering built, Greddy backed, Hing driven Nissan GT-R put the power to the track, and ran a best of 8.793@167.68 mph.

March 16th, 2012 Hing's R35 GTR SPE1000R private track rental at Las Vegas Speedway. Power level at this event was about 1170awhp with 37psi boost. 8.793@167.68 mph with a 1.465 0-60 foot time. 


The car just after launch on the 8.85 pass.  Notice the left rear wheel. 

About 15 feet out from the launch. Notice the left rear wheel.

The thing I see in this picture is the tire tracks on the right side, show the wheel hop with light and dark marks. The car went left, torque steered a bit left, I have found this to be normal with most all wheel drive cars I have driven.


So for about a day, the SP Engeering/ Greddy/Hing R35 held the GT-R quarter mile record. That was until the 1600 whp AMS Alpha Omega(ex-Alpha 12) GT-R showed up to lay it down in Texas for TX2K12. The AMS car managed to peel off a 8.626@173.8 mph pass with a 1.533 60 foot.  8.63 and 8.62 videos are below. The car gets really out of shape on the 8.63 pass, with what looks like the left rear wheel camber and toeing enough to steer the rear of the car to the right. The AMS car has about 6 mph over the SP/Greddy car, showing it is making some power, but it doesn't seem to want to 60 foot as well.  Who is going to be the first into the 7's?




Just after launch on the 8.63 pass. Look at the left rear wheel. Is it an optical illusion?


Just a few more feet forward. Look at the front wheel. Looks almost like positive camber due to lift.


Left rear wheel looks like it has a lot of camber. 

It looks almost like the left rear wheel is steering the car right. That causes a correction, and we see lots of the car in the next snapshot. 

We get to see a lot of the side of the car here. 


The car goes a lot straighter on the 8.62 pass.

Dayanis Garcia Goes for a Ride in a 750 HP GT-R


With the advent of more and more small inexpensive cameras like the Contour HD , the point of view and reaction videos are getting popular.  In this video, model Dayanis Garcia goes for a ride in a 750 horsepower, E85 powered Nissan GT-R, which leaves her grabbing for the door handles. Afterwards, she got a chance to drive the car herself.

Watch the tachometer move. Although I think that part might be missed by most. 

During a DST Motorsports photoshoot we took a short break to take Dayanis for a few pulls in a 9 sec GTR and 750+hp Evo IX.

Fully Race-Prepped GTR Racing in NASA Southeast in 2012


This is what I like to see.  Nissan GT-R's running wheel to wheel on the road course.  In this video posted on NAGTROC, a member, he posts his first two wheel to wheel races in his GT-R at Road Atlanta. Love the standing start.

Here's a video of my first two "wheel to wheel" races in my 2009 GT-R - a fully race prepped (roll cage, full Seibon Carbon fiber, interior removed, racing seat, etc.). The event was the NASA Southeast Competition School which included two races. While there was no "winner" it was all out racing nonetheless. (Due to rain earlier in the day, I was running on R888's versus the usual Hoosier R6 or R100 slicks.)

I have plans to run the car this year in NASA ST2 class after running it last year in NASA Time Trials - TTU. I missed several time trials last year in the Southeast but the car garnered a half dozen or so 2nd place finishes and once placed 1st. In September 2011 I went to NASA Nationals at Mid Ohio and placed 4th overall in TTU. 

Looking forward to a fun season and I'll keep updating NAGTROC with posts...
Check out the video after the break.

233.1 MPH at the Texas Mile : AMS Alpha Omega





AMS is back at it again, this time at the Texas Mile. They managed a fastest speed for Nissan GT-R's with their 1600 whp Alpha Omega with 233.1 mph. This makes this car, both the quickest in the quarter mile, and fastest Nissan GT-R in the mile, with the fastest top speed time recorded for an R35 GT-R.

Yes it is true Ivan and the crew just went 233.1 mph spinning pretty bad. In fact he he got really loose at the top of the track and almost lost it. He was able to save it but took out at cone and cracked the front bumper. So the day is done but they did what they came there to do

197.2 mph in the 1/2 mile
233.1 in the mile!!!!!!!!

29.5 peak boost, 8400 rpm through the traps! He was not out of gear but rather out of aero. He said he could of spun it to 8900 but the car was just too much of handful with stock aero.

 Nice going AMS, whens it headed to Buttonwillow 13CW for some Time Attack?

Stay tuned for some more pictures, videos, and information on the AMS Alpha Omega GT-R.

California Introduces Bill to Exempt pre-1981 Vehicles From Emissions Inspection Requirement


A lot of people complain about the laws, but do very little to actually do anything about trying to change the laws. Here is a chance for you to actually have a voice.  All vehicles newer than 1976 currently need to be emissions tested in California. The new bill that has been introduced asks to exempt all vehicles older than 1981.

In 2004, legislation was enacted to repeal California’s rolling emissions-test exemption for vehicles 30 years old and older and replace it with a law requiring the lifetime testing of all 1976 and newer model-year vehicles. This year, a bill has been introduced in the California Senate (S.B. 1224) by Senator Doug LaMalfa (Senator.LaMalfa@senate.ca.gov ) to exempt all motor vehicles prior to the 1981 model year from the emissions inspection requirement.  The bill will be considered in the Senate Transportation and Housing Committee on March 27, 2012.

We Urge You to Contact All Members of the Senate Transportation and Housing Committee (Contact Info Below) Immediately To Request Their Support for S.B. 1224

  • S.B. 1224 recognizes the minimal impact of pre-1981 vehicles on emissions and air quality.
     
  • S.B. 1224 acknowledges that pre-1981 vehicles still constitute a minuscule portion of the overall vehicle population and are a poor source from which to look for emissions reduction.
     
  • S.B. 1224 endorses the fact that pre-1981 vehicles are overwhelmingly well-maintained and infrequently driven (a fraction of the miles each year as a new vehicle).
     
  • For years, legislators, regulators and stationary source polluters have felt the heat from failed efforts to meet air quality goals and have looked to older cars as a convenient scapegoat, using false data and inflated annual mileage assumptions to further their case.  S.B. 1224 helps validate the truth.  The old car hobby should not continue to carry the burden of past mistakes!
DON’T DELAY!  Please contact members of the California Senate Transportation and Housing Committee immediately to request their support of S.B. 1224.  Please e-mail a copy of your letter to Steve McDonald at stevem@sema.org.  Also, please forward this Alert to your fellow car enthusiasts.  Urge them to join the SAN and help defend the hobby!  Thank you for your assistance.

Nissan GT-R Brake Rotor Upgrades 2009 - 2013

DBA slotted , AP J-Hook and Slotted, AP/STILLEN CCM-X


The Nissan GT-R is a very hard car on brakes. At 4000 lbs with driver and fuel, stock front 380 mm x 34 mm  2009-2011(US) or 390 mm x 32.8 mm (2012-2013), Brembo rotors crack around the cross drilling with hard use. At the track, we see 2-3 track days out of set of factory rotors, some guys can even crack them with hard street driving. Here are a couple of brake upgrade options for the Nissan GT-R. STILLEN will have some iron AP Racing options for the 2012- 2013 Nissan GT-R soon. Email me to get on the waiting list.


DBA Slotted rotor.
The first option for a rotor replacement for the 2009-2011 is the Disc Brakes Australia- DBA(not 2012+) rotor.  The DBA replacement ring is a great option for street driven Nissan GT-R's.  The factory rotors from the dealer are sold as an assembly with hats/bells and come in at more than $1000 per rotor. The DBA 5000 series factory replacement rings are a great street upgrade over the Brembo rotor. They feature DBA's kangaroo paw ventilation system, and propriety alloys for disk materials.These rotors with replacement locking nuts come in at $896 (MSRP) for two front or rear. Less than 1/2 the cost of the factory rotors, and no cross drilling to crack. They do also have a cross drilled and slotted option, if you would prefer. However, if you run your car hard at the track, the next step up is the AP Racing curved vane rotor.

AP Racing Curved Vane rotor in the famous J-Hook face treatment
AP Racing upgraded discs that mount straight onto the OE 2009-2011 brake hats. These discs have been track proven (Nürburgring, Silverstone and more) on GT-R’s in extreme conditions by professional drivers. They not only lasted much longer without cracking, several drivers reported improved brake pedal feel and easier pedal modulation. The best thing is that these upgraded discs cost even less than standard factory replacements.

Click HERE for a video explaining the benefits of these rotors.



The AP rotors have been owner proven in the US the last couple of years. Most GT-R's can go from just a few track days on a set of OEM's to 18-19-20 track days on a set of AP rotors.  The AP rotors are available in two flavors, Slotted, and J-Hook and include new hardware.The J-Hook rotors are for the track junkies, as they provide better initial bite, and provide a constant path of evenly distorted material on the braking face. The pad never loses contact with the braking face, improving the friction characteristics and braking performance. The J-hooks can make a little noise as the rotor passes the pad, a slight whishing sound, but in the grand scheme of Nissan GT-R sounds, its never really noticed. Who uses AP Racing J-Hook rotors?

The slotted rotors are a great option for the street or track guy, that doesn't want to go with the J-hook rotor.

2009-2013 Nissan GT-R 390 mm x 34 mm Brake Rotor Upgrade
390 mm x 34 mm Nissan GT-R Upgraded Brake Rotors


STILLEN and AP Racing have been offering 380 mm x 34 mm front, and 380mm x 30 mm rear bolt on replacement disks for the Nissan GT-R for several years.  The AP Racing 48 vane curved rotors, have been proven by owners in the US, often lasting 5 times as long as the factory rotors under harsh track conditions. 

For 2012 in the US, Nissan increased the diameter of the front brake rotors on the GT-R, but they went thinner(32.6mm) to keep the weight the same.  In a car with braking rotor issues, weighing in at 3829 lbs, this didn't make much sense.  Why not make the rotor 390 mm, and keep the same thickness 34 mm, as the early car?  AP Racing, and STILLEN have answered this question, with an all new 72 vane, 12 attachment point(vs 10 stock), 390 mm x 34 mm rotor that will bolt onto a 2009-2013 Nissan GT-R.

These discs are from a new AP Racing casting specifically designed for heavy sports cars. It uses a 72 curve vane design, using the same OE air gap of 17mm and increasing mass with thicker walls. The result is a disc with higher thermal capacity which is needed on a vehicle that is heavily tracked, very hard to design effective air ducting and sees high disc temperatures.


Nissan GT-R Carbon Ceramic Brake Upgrade

The ultimate brake upgrade for the Nissan GT-R, available for the 2009-2011(stock 380 mm) and 2012-2013(stock 390mm) cars is the STILLEN/AP Racing CCM-X carbon ceramic matrix brake rotors.

STILLEN/AP Racing CCM-X 400 mm carbon ceramic brake rotors

Once found only on the world’s most expensive supercars, Carbon-Ceramic Matrix (CCM) brakes have been developed for the first specifically-tuned aftermarket application – the Nissan R35 GT-R. These 400mm disc assemblies are 20mm larger than the standard 380mm OE iron discs, yet reduce weight by nearly half(38 lbs lighter than the stock brakes). This is rotating and unsprung weight, leading to improvements in all performance categories: acceleration, handling and braking.




Wouldn't you like to lose 38 lbs of rotating, unsprung weight?

After three decades of using carbon-carbon brakes on racing vehicles (even longer on fighter jets), AP Racing CCM discs are the next technological platform. Advancements in materials, process technologies and nanoparticle technology make it possible to use a special carbon fiber precursor along with new, patented process techniques. The unidirectional precursor is needled into a 3-Dimensional, continuous carbon fiber preform. This differs from lower cost technologies that use loose, chopped strand fibers and thin woven face plies bonded on as a friction surface. A true 3D matrix is stronger, more robust and provides longer life than the more brittle alternative. As a comparison, think quality hardwood versus particle board or MDF with a veneer.

Converting the 3D preform to carbon-carbon is done under high heat and pressure via methane cracking during a special carbon vapor infiltration (CVI) process. After initial machine work, a final conversion process results in a full matrix carbon-silicon carbide (CSiC). We call it Carbon-Ceramic Matrix, or CCM for short. The discs are then sent through the final machining, grinding, and balancing. Of course, the CCM discs are now so hard that only special diamond tooling can be used!

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.
