Welcome Ceramic Disc Tech Rotors

[Marc0779]

We believe that for the typical Hellcat driver that there will not be any issue with DD.

With that said, we have seen Hellcats with rustic wraps, mud tires and literally being driven in the sand off-road. We've seen Charger HCs doing donuts in 12" of snow in elevated parking lots, and even a Demon doing 0-60 videos in the snow as well (much love). So with that said, if this is someone's choice of driving, CDT Rotors might not be the best choice for those owners.

In design there is always give and take, and if CDT gave up something, it was tolerance for exposure to extreme debris.

Look at the vents in the O.E. rotor, you could pass a truck through there. There are two reasons for this, mass and, in our view, a silly need to accept debris that cars like this never (almost) see.

Many Hellcat owners don't let their cars see rain, nevermind mud, gravel, sand or salt.

Our rotors are specifically designed for, and intended for performance driving, whether it be 1320' at a time, or road courses.

When you see the actual design for the first time, we think you'll be impressed and you'll understand.

Any plans on making demon sized front rotors?

I assume Demon rotors fit on Hellcats ? …. & those would be even lighter because their smaller ?

Yes 4 piston for demons

 

[Mean Cat]

Yes 4 piston for demons

Will a Demon rotor work with the Hellcat caliper 6 piston ?

 

[Marc0779]

Will a Demon rotor work with the Hellcat caliper 6 piston ?

I dont think it will but not sure

 

[Mean Cat]

I dont think it will but not sure

OK , I wonder what the weight difference is between Demon & Hellcat rotors ? … maybe 5 or 10 pounds ?
I never gave this a thought , about Demon rotors.

Once the development on the 390 * 34 rotor is complete, we will add other FCA p/ns as demand dictates.

From there we will expand to other manufacturers (GM/Ford etc).

Regarding the question of mass, while there are other considerations for each design, a rule of thumb is that the CDT rotor will be 1/3 that of the O.E. rotor (assuming an initial cast iron design). Keep in mind that the hat (actually "bell") will not fundamentally change mass, only the rotor.

So yes, a smaller dia rotor will be even lighter.

One exciting aspect of CDT rotors is a limited ability to customize rotors, but more on this later.

Any new news? I know you said you were working on the HC rotors first but I could sure use a couple of sets for a Demon. If memory serves me, it’s the same size 4 piston setup on the Scat Packs and SRT 8’s, and there’s a whole lot of those around that could definitely benefit from your rotors. Just sayin

Yes I am in

Because we are using a very unique alloy, we are doing a full round of friction material (pad) testing. The latest round of testing came back last month, and while the results were positive, they left room for improvement.

Unlike CF rotors that require not only very specialized but limited friction materials, we are working on demonstrating compatibility with a wider range of materials.

This will enable the end user to have greater range of options, and we strongly feel that this is key to market acceptance and integration. This is, in part, why CF rotors aren't more widely adapted.

Some might ask why not release the rotors with only one option for friction material. If this were cast iron, that might be a path forward. But because our alloy is unique, the rotor design relies on the friction material, the friction material relies on the design. It's an iterative and circular issue, one feeds on the other, and they need to balance so to speak.

And aside from where you stand on the CV-19, the bottom line is that the practical impact it has had on the 3rd party testing facilities in Detroit where we are validating various aspects has had a significant impact on what is already a slow process.

The overall situation weighs heavily on us. The lessons learned are that our enthusiasm for the project and its impact on the performance world, starting right here with our favorite car, shouldn't affect good business planning. Making announcements early (cart before the horse) wasn't the best choice we could have made. The path forward that we laid out at the beginning of the year had us making validation announcements in May. Those would have led into more announcements later in the year. We can't get into all of the details, but the domino affect is more significant than could have been reasonably planned for.

=============

The Good News.

We are moving forward! The design(s), the alloy, and eventually all of the planned friction materials STILL look good!

As promised, the news breaks here, right here, first!

Drive Safe!

Subd. I need to drop weight on my eight sec HC! Otherwise I’ll never get in the sevens. 😂

We saw your run in the other thread.

Very nice!

Thanks. Just getting started. Loosing weight without stripping the car will be one of our goals going forward. We can loose 150 lbs and still meet the MSHS Heavyweight class requirements. The shop we run out of (SRT Autoworks in Phoenix) does a lot of Hellcat brake replacements and also is in the process of working a deal with the Bondurant School concerning their road coarse and drag Hellcats and Demons. Would certainly be interested in talking!

@CDT Rotors ...if you need any actual daily conditions testing, I am willing to try them. I drive around 50 miles a day, commuting to and from work. This includes city and highway driving, about the best real world application of average driving, with some weekends at strip.

As stated before, all "testing" MUST be done before any sales. We hope everyone understands this from a liability and safety standpoint.


With that said, we've specifically set up some early adopters (from here) when we get ready for launch, both in strip, and road course environments. Perhaps there is room for a true DD as well. Post up (or PM if you're more comfortable) your DD commute with a Google maps route (exclude exact starting and ending addresses for obvious reasons) so we can get a sense for what the commute actually looks like. i.e., How much city/Hwy/traffic/time of day.

And state what you're actual MPG is during your commute... Be honest, no fudging up or down.

1) I didn't know this forum existed. Learn something new every day
2) Definitely interested in these. I'm excited to see additive manufacturing graduate to being viable for end-use products.

We've been updating the membership on a casual basis in some of the other sub-forums. The most recent news is that we just came back from testing at full scale, and while there is more to go, the success of this last test is excellent news for the design.
