Porsche application in processs.

 

Have any idea what the price will be on these baby's?

 

No idea of pricing but they seem to indicate based on the different manufacturing process, it will be below Porsche's PCCB. I hope much lower.

 

My guess would be ~$6,000-8,000 for a full set.

They're two piece rotors, so, stoptech should be able to make them fit just about anything. Awesome.

 

This is awesome. Nice to see stoptech bringing this technology to other cars.

 

I spoke to Erik at Stoptech today and they are currently testing these (with great results) on their 550whp supercharged C5 Z06. We should have more info pretty soon, as once the testing phase is done they are hoping to go into production asap.

 

Bye bye PCCB, hello StopTech.

 

Are you guys sure that is all so simple ?
AFAIK CCB work at a higher temp than steel ones and only dedicated brake calipers can handle that kind of heat.

Also you have a lot of suspension pieces around that disk, I think they have to be constructed with heat resistance.
Porsche is the best example with their first gen of CCB that wore out very quickly, this tech is way too complicated to buy it after market and install it in any performance car.

 

Pricing being mentioned by Stoptech on the Corvetteforum is over 10k, but less than 20k.

Based on their post, this product is a superior design to even the factory Porsche ones, due to a different construction technique and physical change in the way the cermic is used. I can't remember all the details off the top of my head, but if you search over there in the C6 Z06 section you will find it in more detail.

Claimed weight savings was 35 pounds total over their steel setup on the same car, which I believe was a few pounds per corner lighter than the factory ones already.

 

So what we are saying is that Porsche can learn something from these guys?

 

Brembo also has a carbon ceramic kit.

 

Porsche dont make the ceramics, they were made in collaboration with SGL Carbon Group.

 

Technology advances so fast these days, based on the information I see, it looks like Porsche and whomever they were in collarberation with, decided that one technique was going to be better for street use, while later it was determined by Stoptech and Brembo that there was another way to do it. It wouldn't surprise me to hear that these guys also have contracts with some major manufactures. I do find it interesting that potentially there will be people who forgo the carbon option from the factory, to get an aftermarket setup.

If its not against board rules, I'll find the post on the corvette forum from one of the Stoptech guys and copy and paste it here where he explained some of the differences.

 

Mod's, feel free to remove this if I am violating anything, post from Jeff at Stoptech regarding their package....response to a thread on corvette forum regarding ceramic brakes.

Man it's getting deep in here...where did I put those hip waders?!?

This is actually a very timely post, as I just had a conversation about this very topic today. My Engineering Mgr.'s Z06 is off the street for a while for some further upgrade work, so I'll be borrowing his ceramic rotors for the next few weeks until my set arrives. I'll be running them daily to work, and hitting Streets of Willow on the 2nd, and Buttonwillow for Viper Days in mid-March. If anyone is at either of those events, you're more than welcome to check them out. My current plan is to install them this weekend. I'll be sure to take some good pics.

The stated goal of our ceramic system is excellent performance on both the street and the track. Our testing thus far has shown our system to be completely street friendly, yet fully 'trackable.' If I put anyone on this board in my car with these brakes and didn't let you look through the wheels, you would have no idea that you weren't driving our standard iron system based on pedal feedback. They work very well cold, have plenty of bite, and a nice benefit is that they give off almost no dust at all.

MajZ,
Carbon / Carbon systems such as what's found on an F1 car are not streetable. They need a great deal of heat in them to generate any bite at all, and simply won't work on a street car. To learn more about this type of system visit: http://www.ndt.net/apcndt2001/papers/1109/1109.htm

The StopTech system is a Ceramic Matrix Composite, which is quite different. Most people would liken our product to the Porsche PCCB system. The most fundamental difference between our product and Porsche's however, is that ours is a continuous fiber, while their's is a discontinuous composite. As many of you may know Porsche is on their third iteration of PCCB. Their systems have had their share of issues with cracking, flaking, and oxidation, particularly under heavy use. If you're into tracking your car, you've probably seen, known, or heard about 911 Turbo or GT3 owners trashing discs or pulling them off in favor of an iron system. We have not seen these issues with the technology we're employing. The best analogy I've yet heard when comparing the two technologies is MDF vs. Plywood. The Porsche system uses many tiny fibers pressed together, while the StopTech system is a continuous strand. They are very different products.

For more details on the basics of CMC technology, here's some light reading : http://www.ms.ornl.gov/programs/ener...f/chap24-6.pdf

The big news with Ceramics is obviously the weight savings. On Steve's car (our Eng. Mgr.), he saved roughly 35lbs. vs. our iron system. To be clear, he was running our four wheel kit with iron rotors...he took off the iron rotors and put on the ceramics, and saved 35lbs. of unsprung weight. The durability of these parts is also tremendous. At this time I'm hesitant to be too specific, but one should expect these rotors to last quite a bit longer than an iron rotor.

As for pads, you will not be able to run your standard friction with these rotors. We have some specific pad compounds to mate with the rotors. That's all I can say at this point about the pads.

The rotor / hat interface we've created is unique as well. We have a trick new mounting system specifically designed for the thermal characteristics of the Ceramics. Keep in mind that Ceramics and Iron have very different properties...they don't conduct heat or expand in similar fashion.

We will be selling our kits as rotor/pad kits for all four corners of the car (4 rotors, and pads for four calipers). You will be able to use the Ceramics with any of our brake caliper systems. In other words, if you currently have our standard iron system on your Z06, you'll be able to buy the ceramic rotors and pads separately as an upgrade. Therefore, you can buy our current system with confidence if you're considering ceramics down the line.

To get an idea of just how expensive the raw materials involved are, read the CMC link I posted above. That doesn't factor in the manufacturing process to create the actual rotors, which is also time consuming and expensive. All I can really say about the final price is to expect something in the range of the Porsche PCCB system and components. Until technology enables it, you won't see quality ceramic systems at iron system prices. It's just not possible. If that's what someone tells you you're getting, they're lying!

StopTech has been working on a Ceramic program for some time now, because we want to be technology leaders in the industry. It's what we're known for. We're well aware that we aren't going to sell a million sets of these rotors and make a fortune in the process. What we want is to provide our customers who are after the ultimate technology with a very special option.

I know you're kidding jas...all in good fun!
