SEMA Stop Tech CC Brake Rotor

[B O N Y]

I am 110% on the same page with Bill and Clinton. Also, I advised Stop Tech that my car remains available for measuring and to do the required 20 stops with each set of brakes.

I'm not even remotely interested in a $15K complete setup. I don't want to change my wheels mainly because there are no good options out there for performance tires in larger sizes that I know of. What good is it to improve your brakes if you have to run truck tires?

I'm still in for the disc upgrade at around $10K if that becomes available.

I'm with you 100% except you can find great tires in 19" and 20", such as Pilots PS2's which I am currently running.

Let's see where we go with Stop Tech. Hopefully they will put together a workable program.:wink

I think most of us are on the same page , so all that are interested in a rotor and pad package just post your preference here. I know Jeff will be monitoring this post. If you want to get up to speed on this thread read post # 56....

I track my car and the last thing that needs upgrading is the braking system.

Yes you have wear and tear and the rotors can crack...
(the picture shows my rotor after 10k miles and 6-7 track days) but they are cheap to replace. If I had to replace them 10 times (vs 1 for 100k miles on the CC) I would still be much better off with the stock.

Going with a 6 piston caliper will negate some of the advantage of the CC lightweight. The calipers themselves will weigh more and so will a 19-inch wheel.

So you start thinking you'll have an improvement but at the end of the day it will be marginal.

A system the can use the stock wheels and calipers is preferred.

I agree with your statement as it applies to a replacement system. But We were clear when we asked for a rotor system only. The savings of 10 to 15
lb's per wheel would be tremendous!!
Also for the record, I do not know if the Stop Tech 6 pot caliper would or would not fit an 18" wheel. The Brembo 6 pot will not but the AP racing will .... so who knows , Jeff could answer that...

Our six piston caliper (ST-60) is rather slim in it's design, and is barely larger than our four piston. It only weighs roughly one pound more than our four piston, so the weight penalty for the additional pad volume is not that great.
The ST-60 fits inside many 18" wheels. I run it on my car with four different sets of 18's. We also actually ran or ST-60 in World Challenge GT on Lou Gigliotti's car for the last three years. Last year he used a 355mm rotor. This year, they moved up to a 15" rotor, and had Forgeline build some trick custom 18" wheels to clear the brakes...barely cleared.:thumbsup

As for the stock GT wheels, I'm not sure. We'll see once we get into it. Again, the problem with doing a rotor-only replacement is the rear rotor. It is a unique size that we currently don't manufacture. Typically on a new size, we need to manufacture a minimum quantity of that size, plus there is substantial design work involved. That means we need to sell enough kits to justify the development cost. What we may have to do in this case is partner up with one of our distributors to commit to buy a certain number of kits. If only a couple guys are firmly committed to buy this product, it's not worth the development. There are too many other projects to pursue, and it's all about opportunity cost given our current workload. I'm not trying to discourage anyone, just being realistic. Thanks, and we appreciate the feedback.:cheers

Jeff.
What is the minimum production run for the rotors that will accept stock BREMBO calipers. They made 4038 FGT's, and perhaps there are other applications as well.

For an iron rotor, that number is typically a few hundred pairs. I'm not sure on the C^3 rotors however, as this is a different process. A few hundred pairs at $5,000 per pair...well, you get the size of the investment we're talking about.:ack:lol

I'm supposed to meet with one of our engineers tomorrow to get this project up on the radar.

We don't sell direct to end-users, so any supporting tuner on this board interested in partnering up on this thing...feel free to give me a hollar. :thumbsup

We maybe able to work through that part of the deal...

 

[DanQ]

While I'm no brake engineer (although I did say at a hoiliday inn last night) I'd be worried that a solution that requires larger wheels would defeat the purpose. The weight reduction of the rotors would be offset by the weight increase of bigger wheels. This upgrade is probably too much for me, but I might still consider a solution that uses stock wheels and calipers...

Who knows, the hot set up might be smaller lighter wheels and make those carbon rotors work harder.

Jeff,
Do the CC rotors create less of a brake fluid boiling condition or are they the same or worse the cast iron rotors?
Also , the guys at the SEMA show gave us a detailed explanation of how the CC rotor material you're using is much harder and durable then the Porsche & some of the other CC stuff that's out there. The guys here are pretty sharp and they might like to hear it from the horses mouth.. I can tell you first hand it looks different...

 

[JRitt@stoptech]

It's honestly too early to go into all of the technical details at this point. We haven't even decided to create this product for the GT yet. As we've always done with our products, we will be forthcoming with all of the necessary details for a customer to comfortably make an educated purchase decision. For the time being, every one will have to be a bit patient. It will be worth the wait. :thumbsup

Jeff,
I wanted to hear more about the material that's being used whether it's for a Ford GT on any other car. Since this material was used on the Lexus F series and the Callaway car I'm sure the info about the material is standard since it is being used on street applications ?
The guys at the show gave a pretty thorough description of the material, It's characteristics and advantages. That info may not have trickled down from Engineering to sales but it's pretty interesting. I'm not sure if it came from John Swank or Steve R may have been both..
I understand we may or may not get what we want but people here like to have all the info to make decisions. The info I'm asking for would only help your product be better understood..

A good chance for you to give us some info on the material ??? See # 76 up there ^^^

Some first-hand observations on the StopTech Continuous Carbon Ceramic brakes

I was talking to Jeff Ritter at StopTech about developments in the ceramic rotor program a few moments ago and he mentioned this thread. After reading it from end to end, I think I can help answer some of the questions that have been raised so far.

What's it like to live with StopTech's Continuous Carbon Ceramic brakes on a daily driver? Do they squeal? Are they grabby or linear? Do they make unusual noises or give a rough feel during high speed stops? We've been evaluating a set on our BMW E46 M3 since August, taking it out in warm weather, rain, frigid cold, and a limited stint at the race track. I've posted our observations to date on the M3 forum and thought you might be interested in what we've learned: http://www.m3forum.net/m3forum/showthread.php?t=177624

In summary, they are surprisingly quiet, even when braking from high speed. Prior to using them, I had expected a rough feel or sound, especially after holding the parts in my hands. I did not expect them to be significantly quieter than iron brakes, almost eerily so. After a couple of bedding sessions, the bite was better than it was with a "traditional" iron StopTech BBK and, so far, the system has shown no measurable wear and has been completely livable. The rotating weight reduction was significant and very noticeable in the way the car handles, accelerates, brakes and rides. I can't wait to replace the StopTech iron 380x32mm / 355x32mm rotors on my Chrysler 300C SRT8 with these.

Speaking of 380mm (15") rotors, I noticed a few wheel fitment questions related to the use of the ST-60 6-piston calipers. My SRT8 came from the factory with 20" wheels, but I use 18" Borbet Type TS wheels for my snow tires. These 18" wheels clear the 6-piston calipers with 15" rotors. Your application will be using 14" front rotors. There's a chance that StopTech can design a BBK for your car that fits under the 18" factory wheels. It will depend on the design of the OEM spokes (for caliper face clearance) as well as the amount of taper in the OEM barrel (for caliper top clearance). I know most of you are hoping for a rotor DRK (Direct Replacement Kit), but I just wanted to let you know it's not automatically a hopeless cause to fit 18" wheels over 14" brakes. My BMW has 14" StopTech brakes at all four corners and I'm using 17" winter wheels on that car. So it is possible.

Dave,
Thanks for the info. Our cars currently run 14" Front rotors with 18" wheels. We feel the stock 4 pot calipers are pretty good that's why we want to keep them. I agree with your statement about the material. The other CC rotors I've seen are very particle board / grainy looking. We'll be anxiously awaiting the completed Stop Tech offereings...

Anything new with these? I think a lot of us are still very interested.

I had some correspondence with Jeff last week. The project is moving .. He hinted they should be brining in a GT for measurements in the next week or so. I try to stay in contact with them to be the squeaky wheel. He did say Spring time so we just need to be patient..
