It looks like Stoptech is starting to make the carbon-ceramic brakes they've been working on. Has anyone heard any word on when/if they'll be making these available for purchase in a Z/G fitment?

I didn't see anything on their site about this (oddly?) and a search didn't turn up anything... apologies if this has been discussed.

 

Good question. I read about this some months back, and then forgot all about it. Maybe ST can include these in their upcoming special edition kit:0

We are accepting orders for our carbon ceramic brake kits and they are not cheap. As of now, the only rotor sizes offered are 380x32 and 355x32 so if you want them for a 350Z/G35, the 4 wheel 355x32mm kit must be purchased. We can also offer a rotor upgrade from iron to ceramic for customers who already have our 4 wheel 355x32mm kit.

Pricing for the complete new kit with calipers is $14,999 while the rotor only upgrade for existing kits is $9,999.

The ceramic 355x32mm rotors with hats mounted weigh in at just under 10 pounds each while the same sized iron parts are 17-18 pounds each so you can expect an almost 40 pound reduction in unsprung weight and rotating mass by going to the ceramic parts.

 

wow, thats half a car.... how much weight will it save? nevermind,, just read your repsonce.

 

Jesus christ that is expensive . . . .

 

Its certainly not cheap, but its still a few grand less than going into a Porsche dealer to buy the complete ceramic kit they offer which our ceramic system actually outperforms.

 

so $10k for rotors alone

how much longer will these last than normal stoptech rotors?

$10k would sure make a car a lot lighter via other things than brake rotors - rotational mass or not

 

When kept in their desiganted temperature ranges they will last upwards of 100K miles which in most cases is the life of the car.

We are well aware that these parts are out of the price range of most of the folks who would like them but at this point the technology is still developing. Costs will start to come down as time goes by but even if they drop by 50%, it will still be out of the price range that most would like to see. It's hard to justify spending $10-15K on brakes, but the people that we see buying them dont need justification...they only want the best and the costs are not important to them. Take the Callaway C16 Speedster..its a $305K car. With the big picture in mind, 10K is a drop in the bucket. The luxury taxes on the car itself will cost more than the brakes do, not to mention insurance.

 

thanks for the info. i was very curious to see how that panned out.

just to understand the technology better, how well do they perform at colder temperatures? supposedly that was a complaint regarding brembo's system.

also, what temperature range are they designed for? i remember reading on the porsche forums that their setup (at least in early gens) didnt really do well on the track, because if i recall correctly, they would flake.

 

Does the Lotus Elise have ceramic rotors? I watched a documentary about the Elise and I remember something about very light rotors, but I don't remember if it was ceramic or not.

 

Wow!!! That's a lot of money for weight savings. The guy building thier Z for track use only I can see making the investment for these. I'm still waiting for more info on that special edition kit. Hint! Hint!

 

so far as i know, no. someone correct me if im wrong

 

Our ceramic rotors rely on a good transfer layer to work properly since they work mostly on adherent friction. The street/light track compound we supply as standard will work just fine at low temperatures, much like any other street pad. If the recommended race pads are used, some heat will be rerquired for the bite to come in, but that is the nature of a track oriented pad on iron systems as well.

Concerning the flaking of the Porsche PCCB systems, that is more to do with the construction of their rotors than anything else. Their rotors are made with short chopped fibers in the core of the rotor with longer continuous fibers layered over the top to create the friction surface. Its easiest to compare this to particle board with a veneer surface. When these systems overheat and oxidize, the veneer surface tends to delaminate and flake off which caused a lot of issues for them. Our technology uses continous fibers throughout the rotor which leads to a more robust part that also will run cooler. The best comparison for our technology is plywood which is much more robust than particle board.

We are still testing the parts to get the recommended temperature ranges locked down but we already have been able to verify that they can handle more temperature than what other manufacturers can. We will be out at the track this upcoming weekend and will probably be able to finalize the data that we have come up with so far. As with any system, there is a maximum temperature that the parts can handle before they will fail and at this point with the high cost of the parts, we are still recommending hardcore, high powered track only cars stick with iron parts since the replacement parts are so much cheaper and more readily available.

 

I just put my ceramics back on my Z06 today...along with some TE37's. Yes, I'm not kidding...TE's on a Z06.

Dude, those are totally Rotas....you're not fooling anyone

 

I really, really want this . . . . if I didn't go FI I would seriously consider getting these. The weight reduction is so worth it as I would like as little rotational mass as possible because my crew and I go to the twisties at least 4-5 times a week. And we have some insane backroads up in Washington.

 

Just looked at the rotors in those pics and noticed that they aren't cross drilled. Correct me if I'm wrong, but aren't the carbon ceramic rotors on the Porsche's and the Mercedes SLR McLaren cross drilled?

Any specific reason for a plain rotor on your system versus the others? And do you plan on offering a cross drilled and/or slotted version(s) of your carbon ceramic rotor?

 

Cross-drilled rotors crack on the track . . .

 

Bump for Stoptech's answer to my last post.^^

 

im guessing this is stoptech work
congrats on the development


i wonder what lexus pricing will be
