[sadil]

LOLL, please tell me that each is a typo and that is for 4.

[KDR83]

I think for a Porsche Panamera they are $7k each so I believe it

[ViperSmith]

Mopar list is always sky high

[swexlin]

Exactly, so just the rotors alone are over 10% the cost of the whole ACR? Buy an ACR, and part it out for more than you paid!

[XSnake]

They were around $3,100 each for fronts when I looked them up awhile ago

[Voice of Reason]

Don't forget new rims if you're putting them on anything other than a Gen V ACR. Ouch.

[ACRucrazy]

And calipers/pads.

[VENOM V]

Anyone know what Corvette carbon rotors cost? Mopar had BETTER price them similarly. It would be a bad move to have the cost of the competitor's CCBs a lot lower. They are probably purchased from the same manufacturer for a similar price.

[ACRucrazy]

IIRC you can swap all 4 rotors and calipers on the corvette for under 10k? I haven't followed in a few years so I am unsure if prices changed.

[mjorgensen]

Mopar does not care what ANYONE thinks the prices should be...

[VENOM V]

Mopar does not care what ANYONE thinks the prices should be...

LOL, it's sad but true Mark. However they did reprice the carbon aero parts after initial pricing was astronomical. They did listen to the customers there, this seems like a clear opportunity for them to do the right thing and price this correctly too

[KB Viper]

i know ZR1 rotors were close to that at list price but almost any dealer would take 1k off each if you asked.

[Chipster]

Aren't CCBs an 8500 option on the GTCs? But it's double if you wanted to buy from MOPAR separately?

[Coloviper]

Can go through a lot of steel rotors for that coin. Can probably change out steel ones after every hot event and treat as disposable need for those kinds of costs.

My question is, are they really worth it? I think the bigger brakes and 6 piston calipers, etc. are but are the CF rotors really worth it? I am struggling to see where they are.

On the plus side, be thankful it is not a Bugatti and having to replace those. I believe they are like $25k per rotor or something outrageous like that.

[XSnake]

Hardly, check the price of the Brembo 2 piece rotors at your local dealer......over $1k each on the fronts.

IMO though, they aren't worth 3x the price. But, everyone was bitching how they weren't available before this. Now, everyone is going to bitch about the price.

[serpent]

Good way for the street only ACR owners to recoup the money spent on car that won't be doing any track duties. Just swap back to the setup that comes with the base srt.

[01sapphirebob]

But, everyone was bitching how they weren't available before this. Now, everyone is going to bitch about the price.

This.

[SHADOWSNAKE]

If I recall, dealer quoted me $1800 per rotor on my C6 Z06/Z07. But, why would I replace them...just don't put a crack in them when you remove/mount wheels and they should last a LONG time even with track use. I believe the CCB cars (ZR1s) at Spring Mountain have been continuously tracked without need of new rotors, just pads.

[ViperSmith]

Just wait until Viper owners have to deal with the average dodge dealers chipping their CCB rotors taking rims off and dealers blaming the owner.

[ViperDC]

But, everyone was bitching how they weren't available before this. Now, everyone is going to bitch about the price.

Naturally.

[VENOM V]

I have spent a lot of money on steel rotors- replacing them, turning them, Etc. Dealing with swapping track pad/rotor sets with street pad/rotor sets. It is a pain in the butt and not cheap.

I will see first-hand how long the CCBs last as compared to steel. So much conflicting info out there on how long they last. The CCBs on the ZR1s at Spring Mountain typically lasted 15,000 track miles. I remember tracking Z06s with steel brakes there, sometimes with pedal pulse due to pad build up on the steel rotors, or perhaps warped rotors. However every ZR1 I drove there the brakes were fantastic. But I've heard other things from other track rats. Need to find out for myself. It will be fun.

That old news. I posted that several months ago.

2016 ACR Dive planes are $2100.44 EACH!!!!!!!

[Voice of Reason]

That old news. I posted that several months ago.

2016 ACR Dive planes are $2100.44 EACH!!!!!!!

That's pure insanity right there, the guy with the idea of buying an ACR just to part out is onto something.

Steve have you seen any prices for the diffuser pieces?

[ACRucrazy]

Only if you find a buyer at those prices. Which there will be 0.

[FLATOUT]

Another reason to buy the ViperExchange Big Brake kit.

[mjorgensen]

Just an FYI, the CCB option also has 4 different knuckles (all CCB specific part numbers) to make them fit, so I do not think it will be an easy swap to just switch to the steel brakes if you want to, List price for those parts alone are close to $7500 alone....

Hopefully they will last a LONG time and be much more robust then the steel options out there.

[ACRucrazy]

I will take an ACR 1 of 1 with steel rotors please. :)

[allans]

I hate to say it but, this could be a show stopper for me. Just a mild off-track excursion could result in a $25000 expense to replace the splitters and maybe 1 or 2 rotors. Just catching a stone in a caliper could be big $. Besides, I don't know anyone, who tracks their car HARD, who would deliberately choose ceramics. For typical de's i'm sure they will be great. Just don't get off the track surface. Best, Allan

[SSGNRDZ_28]

Are there steel rotors and pads that would be a direct replacement for ACR owners who start with carbon ceramics?

[VENOM V]

Well I'm not gonna get my panties in a bunch quite yet. I'm gonna drive the wheels off of it, have a blast, and see how I like them and how long they last. Another thought- it'll be a while before I wear them out, I'm certain of that. By then we will have all beaten up on Mopar and they will have come down. Just maybe, lol :United_States:

[ViperSmith]

If the demand is there someone else will make replacement rotors

[Dan Cragin]

For most owners, those rotors will last the life of the car. For track rats that may be different. We track our cars with many McLaren's, I have seen one go through 4 sets of pads and the rotors still weigh out close to new.

Price of admission.

[VENOM V]

Crazy idea: If I end up liking steel over CCBs, I can swap my GTS's steel brake set up onto the ACR. This could work. Not so crazy. On my GTS, I have TA front rotors and track pads and ducting. That would probably be enough for the ACR. Worst case, I could get a big brake set up for the ACR's fronts. And the GTS would have CCBs which would last virtually forever on the street. Ok, not so crazy. This isn't a bad idea at all.

For that matter, anyone with CCBs could swap brakes with a TA, SRT or GTS owner, plus a cash equalizer. For the occasional tracker, I bet the CCBs would be perfect. For the hardcore track rat, verdict is still out.

[ACRucrazy]

As mjorgenson stated, all 4 knuckles are also different to use the carbon rotors.

$7500 for 4 knuckles
$16400 for 4 rotors
$$$?? for 4 calipers
$$$ for 4 sets of pads

[ViperSmith]

Are the knuckles just to accommodate the larger CCB? I.e. Would smaller brakes fit fine (aka if you had steel you need the larger knuckles to fit the CCB)

[Coloviper]

Does the VE big brake package need new knuckles? Why are they needed?

[XSnake]

I'm guessing the knuckles would be different as the CC calipers mount differently to them.

[Voice of Reason]

As mjorgenson stated, all 4 knuckles are also different to use the carbon rotors.

$7500 for 4 knuckles
$16400 for 4 rotors

Plus $6,800 for ACR rims.

You're at $30,700 (MSRP) before you've purchased the calipers and pads.

[TheAnonymousOne]

My cousin's best friend is a regional manager for Carmax. He said when the ZR1s were popular, they we're getting them in left and right because the owners could not afford the $20k brake job. I'll never understand people buying things they can't afford. It reminds me of the Lambo owners making $250k a year or even less!!! I love the ACR extreme but I definitely can NOT afford a brake job like this.

Seems to me it should be possible to have an iron friction ring made of the same dimension and change pads. I had rings made for my McLaren and for my Radical. Now blanks that big may not be available, but I'd look hard

[Racingbrake]

Both CCM replacement and iron conversion rotors will soon be made available.

We have offered iron conversion for those cars come with CCM rotors as default (Ferrari F430, F458; Corvette ZR1, Camaro Z28), or as option (Aston Martin DBS, Audi R8, BMW M3/4, Merceddes GT S, Pccb 997/991 GT3)

CCM replacement rotors are also offered as upgrade for those cars that CCM is not available (like for non ACR-E) as option typically for Nissan GT-R & Camaro ZL1.

Required CCM rotor rings (made by Surface Transforms in UK (http://www.surfacetransforms.com/index.php)) and iron rotor rings (made by RB) are in stock ready to be built.

Curious to hear what upgrade from iron to ccb would be for standard cars

[Racingbrake]

We will use the same ACR-E CCM replacement rotors (front and rear) and build a complete brake kit (w/ RB calipers) for non ACR-E owners to upgrade (CCM or Iron) - The only difference would be the calipers (OE vs. RB). So if you will have to purchase ACR-E 6pot/4pot calipers from Dodge (because your original calipers are too small), or purchase the complete RB brake kit.

Being this brake package offers the same rotor kits (CCM or iron), they are compatible (w/bolt on installation) for all Viper's (V 3/4/5), which can also help to increase the demand beyond just ACR-E.

This is the same as we offered for Porsche 991 GT3 w/standard iron brakes (380/380 kit) with option upgrade to pccb's (410/390 kit) with CCM or Iron.

Not to our knowledge. The only thing we heard is from Ferrari community that you have to re-set the computer by the dealer to calculate the life of CCM rotors (by the number of stops), but of course you will have to pay $6,000/rotor instead buying from aftermarket. How accurate (computer) is another story, because brake is not like oil change frequency so we always advise customers to check/inspect manually (after track event) is still the most reliable way to monitor the life of CCM rotors.

For Porsche, Corvette ZR1/Camaro Z28 people are swapping between CCM and Iron w/o any issue/concern.

[est8esq]

I agree. But, coming from a GT3 and one of the first adopters of aftermarket components everywhere for the car, I didn't find the replacement rotors for the 991 GT3 to be the better solution NOR cost effective to replace the OEM steel rotors that Porsche had??

If someone for Viper comes w/ alternatives, but creates a pricing point that prevents a barrier to purchase, then alternatives aren't really alternatives, IMO.

Give us competitive and fair costs on aftermarket and we'll beat the door down to buy. At least, I will anyway. Speaking for myself, I just don't get why "racers", club, pro or otherwise always seem to bear the brunt of usurious prices?? If you have the machinery, it's not like reinventing the wheel?:witless:

I've confirmed the OEM CCBs use different programming for the ABS/ESC than the steel brake system. The CCB rotors are not a heatsink like the steel rotors. The pads and caliper must absorb the heat. In any case SRT does change ABS/ESC programming. Knuckles are also different.

[Racingbrake]

I heard the same ABS/ESC programming scare in various communities but found no proof as of yet that replacing the rotor material can actually affect the braking performance (except re-setting the info computer) which I will be all ears if someone can elaborate that.

CCM rotor functions exactly the same as an iron rotor, the only difference is their respective characteristics due to different material. You may want to learn further on different CCM rotors here:

[Bill Pemberton]

Welcome as a new sponsor , and before some of us could respond that no worries about the cost , someone will come out with less expensive replacements in carbon and steel, bingo you answered all the concerns. Will agree that the likelihood of the different mass of a steel rotor changing the ABS dynamics is not highly probable , since the same fear was addressed with many folks who went from 19 inch rims down to 18s on various vehicles. Seems everything worked fine with all the trackrats I know, and would imagine your experience with your customers justifies that not a big chance of problems with different composition on the rotor. Thanks for sponsoring the VOA Forum.

[allans]

Just to let everyone know, Racing Brakes has been a sponsor on the the Porsche Forum -rennlist- for a few years and are well regarded. Lots of guy's have PCCB's and they retail for almost $8000 per corner, so several have converted to steel or purchased RB's Carbons as replacements for the factory rotors. Hopefully, prices will reasonable for our ACR's. Best, Allan

[Racingbrake]

Although this CCM Re-furbishing service may be little too early for you but I would like to share with you - the same information we just posted on rennlist and GT-R.

Here ST is the abbreviation of Surface Transforms from UK (http://www.surfacetransforms.com/index.php) who is the manufacturer of CCM-X discs, which is a continuous carbon fiber process than Brembo's chopped fiber.

You can refer to our introduction thread below and learn more about the difference in process and their strength/thermal characteristics.

Carbon Ceramic Brakes (http://forums.racingbrake.com/showthread.php?t=1484)

---------------------------------

Carbon Ceramic Disc Refurbishing
One of the advantages on CCM rotors, aside from being better in thermal characteristics, is that the disc is refurbish-able and the cost is lower than a comparable iron disc.

We recently helped a GT-R customer have his car set of ST CCM discs refurbished.

Turn around time is about 4-5 weeks.

09/29/15 Discs shipped to ST
10/05/15 Received by ST
10/28/15 Refurbishing complete, return to RB
11/02/15 Received by RB

1 week to ST in UK
2-3 weeks for order processing
1 week to our facility in CA

The refurbishing cost is $450/rotor less shipping charge, which is about $96/rotor for a round trip or a total of $546/rotor.

For customers who purchase CCM rotors from us, we will waive handling and service charge for inspection, cleaning rotor hats, dis-assembly before we send to ST and re-assembly after returned from ST. Damaged hardware will also get replaced all these are performed at no extra charge.

friction ring and pad pricing, please?

Sorry we don't have this info yet nor I think OE replacement ring will be sold separately. As an example ZR1 discs are popular for aftermarket retrofit CCM rotor kit especially in GTR community (http://www.gtrlife.com/forums/topic/110727-racing-brake-zr1-carbon-ceramic-kit-for-gt-r/), which we also offer but we must purchase the complete rotor assembly, so we ended up have a pile of unused rotor hats.

We believe the brake pad is the same as ZR1/Z28/F430/F458, which we will know more sometime next week after we receive caliper order from dealer. If so the OE pad should run you around $900-$1200 per car set, or other aftermarket like Endless W007, Pagid RSC, and our sintered pad are available with a price ranging $1000 - $1500

Reference thread: In Quest of Ultimate Brake Pad for GT-R..With CCM Rotors (http://www.gtrheritage.com/topic/4467-in-quest-of-ultimate-brake-pad-for-gt-rwith-ccm-rotors/)

[Racingbrake]

what would the out the door cost be for a CCB kit cost for a non ACR? I would want 380 x 32 front and rear 2 piece rotors, with 6 piston fronts and 4 piston rears including pads and SS brake lines?

In general 380mm rotor kit can fit 19" wheel more comfortably than 390mm, while our default CCM is 380x34mm - Same as Ferrari F430 and Porsche 997 GT3 pccb.

We estimate 380x34 CCM rotor kit (2 rotors) will run around $5,500+/-.

[Racingbrake]

Based on Dodge dealer's quote:


Front P/N 68252788AA
Rear P/N 682527866AA

Both are same price at $4,100 before any discount.

[est8esq]

I've learned that dealer costs for OEM CCM rotors are around $5,166.00 a pair or $2,583.00 a corner or even less? Pads for fronts are around $534.87 for fronts and $396.90 for rears, again probably less.

If anyone can get replacements at cost or close, then based on wear OEM's may not be such a bad proposition after all?

It's going to be all contingent upon wear, how many track days these rotors and pads will hold up??

[Racingbrake]

How much you think a dealer would sell for a pair of rotor and pad after their mark up?.

Consider future maintenance you must purchase the whole rotor assembly from a dealer again vs. RB's re-furbishable feature (cheaper than iron replacement) as presented above, or replace only the rotor ring at a fraction of rotor assembly cost (hats are re-usable). So clearly RB CCM rotor has its advantage.

The reason Porsche tracking drivers swapped their OE pccb to iron rotor was mainly due to the earlier generations CCM rotors were not as durable, and there was hardly any aftermarket CCM rotor available while dealer costs are prohibitive.

[lmcgrew79]

The rear brakes on a z/07 $1600 and the z/28 $1300 both use a 390 rotor, not sure if the mounting holes are the same but for that price you could chunk the hats and just use the rings?

[dethred]

Anyone know what Corvette carbon rotors cost? Mopar had BETTER price them similarly. It would be a bad move to have the cost of the competitor's CCBs a lot lower. They are probably purchased from the same manufacturer for a similar price.

Then you can go ahead and assume this is what they'll do anyways.

"Guys, guys, I just thought of a great idea to further reduce sales and discourage brand loyalty! Let's price our ACR parts so high that the only way you can reasonably have them is to buy the entire car! Sell one CCB set for 4x more than a Corvette's, and lose 10 customers in the process. Win/Win/Win!"

Discussion is based on CCM rotors (not iron)

[XSnake]

Discussion is based on CCM rotors (not iron)

And the same principal will apply imo

[Racingbrake]

For CCM rotors, unlike aftermarket iron rotors (Stopech/Brembo) that you can just replace the iron ring, you must purchase the complete rotor assembly, neither GM nor Dodge dealers will sell just the replacement CCM rotor ring.

With RB/ST CCM rotors initially you purchase the complete CCM rotor assembly, but afterwards you re-use the hat and have your CCM rotor rings re-furbished, or replace just the "CCM rings"

CCM Refurbishment costs less than iron ring (comparing to iron two piece), even CCM replacement disc costs only fraction of the CCM rotor assembly - So it make more senses than OE's CCM rotor options.

[Angleiron]

Just something to read and consider...

Truth be told, as under-appreciated as they are, brakes cannot be ignored as a significant piece to the high-performance puzzle.

“Brembo launched the carbon ceramic materials (CCM) project in 1998 and after 4 years of research and testing the CCM discs were used for the first road application on the Ferrari Enzo,” says Monica Michelini from Brembo Media Relations. When the Ferrari Enzo launched, it cost a whopping $658,330. Today an Enzo regularly sells at auction for above $1,000,000.

That Ferrari ushered in an era where road vehicles used parts and technology developed for one of the most extreme Motorsports: Formula One. The Enzo has an incredibly light carbon fiber body and a quick-shifting transmission that uses two steering-column mounted paddles to change gears in 150 milliseconds. It even has active aerodynamics and a sweet sounding V12 engine that pumps out 660 horsepower and 485 lb-ft of torque.

Finally, there are the brakes. Brembo used the carbon-ceramic technology from its Formula One program and applied it to the CCM brake discs found in the Enzo. Now you can find these carbon ceramic brakes in all Ferrari models and in supercars like the Mercedes-Benz SLR McLaren, Pagani Zonda, Aston Martin DBS and the Chevrolet Corvette ZR1.

WHAT DO THEY DO?

All these cars feature serious engine performance, but what goes fast should also stop fast. Since brakes slow cars down using friction, they also tend to get extremely hot and can deteriorate in terms of performance. Carbon ceramic brakes are actually designed to withstand the usual intense heat that occurs during braking. According to Brembo, this heat resilience cannot be easily replicated with the usual cast iron materials found in most brakes.

At high temperatures, carbon ceramic materials are also less resistant to deformation or warping, which means that they should last a bit longer than traditional brakes. Finally, carbon ceramic brakes don’t corrode, even when in contact with water or salt during the winter seasons.

“This feature means that the wear resistance of Carbon Ceramic Material guarantees an approximate disc life of 150,000 km (93,000 miles) for road use and 2,000 km (2,400 miles) for extreme track use (e.g. Ferrari Challenge),” Michelini said.

That’s not all. Carbon ceramic brakes also look pretty cool. “The very high technological content of the carbon ceramic and their superior aesthetic appearance make them the ideal product for sports and luxury brands,” Brembo communications manager Caroline Fallara says.

These are nice features, but aren’t nearly as important as the biggest advantage of carbon ceramic materials: weight reduction. Carbon ceramic materials are 50% lighter than cast-iron discs, which reduce a car’s unsprung weight and should improve handling and driving dynamics.

“Carbon ceramic brake rotors offer tremendous heat dissipation benefits simultaneous with very low mass,” says Ron Younkin, Chevrolet’s engineering manager of brakes, rear-wheel drive and performance cars. “The low mass rotors enable superior suspension tuning while their braking performance on the track allows consistent braking even when pushed by professional drivers who demand the most from their cars on their race laps.”

BUDGETING FOR BRAKES

This all sounds pretty great, but there’s a price to pay. While swallowing the added cost might be justifiable on a vehicle that already costs $300,000, affordable performance machines increasingly offer carbon ceramic brakes as well.

Take the $83,000 Porsche 911 Carrera, for example. While far from cheap, it’s certainly more accessible than a Ferrari of Lamborghini and can be equipped with the pricey brakes – a steep $8,520 addition. Further down the scale, these high-performance components can now also be factory equipped on cars like the BMW M3 or Porsche Boxster, both of which are about $60,000.

Some feel that carbon ceramic brakes aren’t worth the extra cost as AutoGuide’s own Ken Glassman said during his 2012 BMW M6 Cabriotlet review.

“Despite repeated heavy braking, its 15.7-inch front and 15.6-inch diameter rear brakes never showed any sign of fading, and our tester wasn’t even equipped with the optional carbon-ceramic units.”

With an endorsement like that, why even get the higher-cost brakes? Other high-performance vehicles, like the Audi R8, Nissan GT-R and even Dodge’s old Viper aren’t equipped with carbon ceramic brakes, and can stop as fast, or faster than vehicles with the high-tech material. In fact, some independent tests have them stopping in as few as 100 feet from 60 mph.

“Stopping distances are controlled first and foremost by the tires’ adhesion and grip to the road,” explained Younkin “the brakes simply are the mechanisms that slow the tire. A ceramic brake provides torque just as a metal rotor does.”

WHY IS CARBON SO SQUISHY?

Price isn’t the only drawback of these high-performance brakes. A common complaint is that there’s less braking feel during the first part of pedal travel – especially when cold. One reason for this is that the optimal operating temperature of the carbon materials is much higher than those found in normal brakes. Once the brakes heat up, under serious track use, then they feel more “normal.”

Weighing the benefits and drawbacks of carbon ceramic brakes, it’s clear that they are ideal only for those who really need them – or for those who like spending money to make a fashion statement.

For anyone thinking of frequently or even occasionally taking their car to the track, a carbon ceramic braking system is a wise choice for better lap times and even more fun. There are some (very small) advantages for the road-only drivers, like the longer life of the brakes, but for many thousands of dollars it’s not worth the added cost.

[05Commemorative]

Just ask yourselves one simple question: If CCB cost the same (or even within 50% more) than Iron, would you choose them over Iron?

For me, absolute yes no brainer. Lighter, no dust, can go bigger because lighter, last longer, less resistant to heat. In virtually every way you judge brakes, other than cost, they are better.

[Racingbrake]

The performance of a sports car is shown not just by its acceleration but also by its deceleration values. Carbon ceramic brake disks open up completely new dimensions.

The CCM-X weigh around 50 percent less than conventional gray cast-iron brake disks. Other advantages include:


Much better braking response
Higher fading stability
Very good control
Better directional stability
Prevention of brake dust
High thermal stability
Corrosion resistance
Wear resistance
Exceptionally long brake disk life

[Racingbrake]

We have obtained OE calipers from Dodge. After fitting with spindle and rotor, it turns out the front caliper would fit 36mm rotors better (piston will stick out less) than OE's 34mm rotor. So we will use the same disc as ZR1 394x36mm.

With current OE set up the actual pad contact area is only 385mm in diameter, so with RB CCM rotor kit will include a spacer to effectively increase it to a full 394mm rotor kit.

Advantage of RB CCM rotor kit:

1. Bigger rotor provides longer brake torque arm for more effective braking torque.
2. Large and thicker rotor increase the thermal capacity and can extend rotor life.
3. Rotor hats and hardware are exclusively designed by RB for easy assembly/dis-assembly w/o damaging to mounting holes.
4. RB rotor hats are designed to promote more cooling air circulation and machined from forged aluminum alloy (6061-T6) for extra strength and stiffness vs. machined from billet.
5. Lots of supply on ZR1 rotors at much lower cost from GM vs. Dodge which most of you already know.
6. After you purchase the rotor assembly from RB you can just replace the rotor rings from GM dealers or Amazon.
7. Compatible brake pads are available to be bundled in our CCM rotor kit.

[Racingbrake]

Yes ZR1 pads will work on Viper OE calipers and CCM rotors.

[Racingbrake]

Can anyone check if existing stock CCM and stock 19" wheel still has extra 2.5mm (1/10") for the ZR1 CCM rotors.

[ACR]

RB are the ACR rotors refurbishable? Some manufactures do not use a full 3D-CCM rotor, they use a 3-ply process, the latter can not be resurfaced

[Racingbrake]

RB/ST discs are re-furbishable at a cost lower than iron replacement as presented earlier.

Brembo OE CCM discs (aka ZR1 discs) are not being refurbished to our knowledge. There is a company in Europe called Sicom claiming can do it but its durability and value/cost is yet to be proven especially for track applications.

So it all amounts to cost/durability. For tracking we highly recommend using ST discs, but if just for general street driving and cost is major factor then ZR1 discs are deemed to be adequate as no re-furbishing is anticipated.

Here is a recent track review on RB/ST discs by a GTR track driver.

I have been reading hundreds of threads in this and other forums about "pccb" or not "pccb" or something to that nature and for sure many more to come but I have yet seen a fact sheet comparing these two type of rotor materials:

Carbon Ceramic - Known as pccb (Porsche Carbon Ceramic Brake)
Cast Iron - Commonly called as "Steel"

So here is.

This is a quite informative thread.....my question is if one orders a 1 of 1, is it worth the expense to spend 8,100 more dollars for the CCBs? If you are not hard core racing, what is the difference in replacement times for Steel vs. CCB, and is a significant difference such that the expenditure for the CCB is warranted?

I am ordering a 1 of 1 in '17, so this would be valuable information for me.

If you are not a hardcore racer you will never have to worry about replacing the CCB rotors and will get all the benefit that they provide for the car. If your ordering an ACR, you absolutely should get it with the factory equipment i.e. CCB's.

Resurrecting this thread since there now appear to be 18" wheels out there.

First will the ZR1 rotor with new hat clear 18s? I suspect not as it looks like rotor OD goes up a few mm (anecdotally, I have placed ZR1 rotor on top of ACR rotor and it looked like the diameter was at most 2mm bigger in ZR1, but I did nothing precise.

Second, will the RB supplied rotor assemblies replace the ACR OEM with no dimension change to diameter and caliper location? A bit more thickness is fine so long as pads fit in calipers, or even better what about slightly thicker pads for more pad life.

If the extra 1mm in radius fits without relocating the caliper nothing about the wheels will have to change.

[kverges]

Understood, but Post 146 mentions spacer and I wonder if it is essentially a washer under the radial mount bolts to move caliper out, such as was done on ACR-X in 2010. Anecdotally, Ben Keating had a front wheel separate due to caliper stud machining barrel at Miller Motorsports Park and he came over and hit me - my initial thought being WTF?

[Racingbrake]

ZR1 rotor is too tight for OE 6pot caliper w/o relocating the caliper which will not fit under 19" wheels.

Even for stock ACR-E CCB set up, the actual pad contact diameter was only 385mm (instead of full 390mm). This "not quite exact" fit can however, make more room for wheel clearance.

We have CCM rotor kit that are designed for a "bolt on" installation for G3/G4/G5 - Spindles (front and rear) remain intact, keep the use of rear 4 pot calipers, the only thing to add is a set of front 6 pot calipers.

The front rotor is interchangeable with ACR-E CCB, but not the rear due to different set up (caliper & spindle) as the rear CCM rotors are designed to fit existing 4 pot rear caliper and spindle.

When it comes to CCM brakes it's better to rely on a professional brake company like us as it's definitely not an ordinary DIY brake retrofit project in cost and adventure.

We just shipped a complete CCM brake kit (w/ZR1 C7 394/390mm rotors and RB calipers) for a Challenger customer today. So CCB rotor assembly with ZR1 rotors for ACR-E CCB replacement (as well as G3/4/5 upgrade) was revisited.

Following is our conclusion:


RB can develop a rotor kit using ZR1 rotors (394x36mm) for a bolt on installation to G3/4/5 spindle w/o modification.

This rotor kit can fit under Viper OE 6-pot calipers, but due to the rotor will have larger diameter than stock, while we want to keep the same radial wheel clearance as stock set up (w/o spacing the caliper out), so OE calipers and pad hardware required modification for proper clearance.

OE brake pads may need to be trimmed at bottom (or you can use modified ZR1 stock pads) to clear rotor hat.


The good news is now you no longer have to worry about expensive rotor replacement cost, and we are capable of providing such a "turn-key" CCB rotor package, for a low cost and easy installation. After that you'll be running your brake just like Corvette owners in rotor and pad replacement.

We also verified 36mm thick rotor can fit OE calipers better (vs. stock's 34mm) so this rotor kit can increase your thermal capacity over OE set up.

Want to switch to iron rotors? No problem, we have them.
