New carbon ceramic brake disc option

A5/S5/RS5
#5

Picked these up today, another R8/Huracan/Gallardo replacement set. The fronts fit the RS5 with the CCB option and as mentioned, far more durable than the OE CCB rotors at about half the cost. ST was supposed to send me the iron rotor upgrade set (same diameter but 34mm width instead of 38mm). These have entered full production with the next batch being done at the end of the month.

Not cheap but easily the best brake rotors on the planet bar none. The come in at 13.8 pounds front, about 9.8 pounds rear.

I have a B9 RS5 with the non-CCB brakes. I’d be interested in these if I could get a matching front and rear set.

#7

Unfortunately the B9’s have a completely different rotor setup from the B8’s and the R8 so there aren’t any plans at this time to make a fitment. The rear setup wouldn’t be as advantageous due to the small disc size plus I can’t see many B9 owners spending $12,650 on carbon rotors.

Now if there’s enough interest, we can produce them but it’d take at least six owners willing to commit with a deposit.

The B9 front rotors (iron) are 375x36mm and those dimensions aren’t shared by any other brake disc for current Audi vehicles. On the B8/B8.5 RS5, the front rotors and calipers are the same as the R8, Huracan and Gallardo so there was a good business model to bring that fitment to market.

These rotors will be used in the United States International GT Car Racing Championships btw…International GT is a North American racing series that includes three different championships for late model Porsche and Ferrari competitors. Home primarily to sports drivers, with the occasional professional driver/coach joining the action in endurance races, International GT annually presents The Stuttgart Cup, Mission Foods GT3 Cup Trophy and The Maranello Cup championships. The Stuttgart Cup includes Cayman 3.4 and 3.8 liter cars. The Mission Foods GT3 Cup Trophy features 996, 997 and other GT3 Cup cars from the last decade. The Maranello Cup includes Ferrari 360, 430 and 458 challenge spec cars. All classes compete for season-long sprint championships.

So pretty serious stuff which’ll really illustrate the benefits of the ST rotors over iron and traditionally manufactured CCB rotors.

Ok fair enough. I know there are some people who are pretty serious about tracking their B9 RS5s, they even have a Discord https://discord.gg/XxEVpstf so there probably would be a few people interested in this. If RS4 owners are included you’d probably have even more. Too bad the B9 uses a unique brake rotor size.

#9

How open would that group be in me joining and asking if there’s interest? Or…you could point them to this thread if you’d like. I’d be happy to answer any/all questions in regards to the rotors.

Yeah not sure why Audi felt the need, in this one instance, to use a unique size. I thought for sure it’d be the same rotor as say the RS6 or S6 iron rotor but it’s completely unique in diameter and width.

They could have even carried on with the B8’s 19Z caliper and CCB rotor. The new RS3 is using that caliper and assuming the same rotor (380x38mm) for it’s CCB setup.

I’m sure it would be fine, they already have several other vendors in the group. I’ll ask the mods tonight (Discord is block on my work laptop) and I’ll also post the link to this thread.

I just sent you a PM.

Hi Ape,
Do you do any other brake options.
My disks are coming to end of life so will be needing to change this year. As much as I’d love these I do not have that sort of money. Wondered if your able to maybe help me though or even any advice for me what I should look for. Or am I best just replacing

#15

You have CCB front discs? As of now, there are no replacements for the 380x38mm CCB disc with an iron rotor. Plus they’d be really, really heavy. I may have one source for something, let me reach out. Just know there’s a shortage, industry wide, of iron rotors. The foundries are experiencing a major disruption in raw materials so if there isn’t something in stock, it likely won’t be soon.

#16

Do me a favor Mick, shoot me an email. sales@redmistracing.com.

Also know the price is in USD and being in England, you’d have a favorable exchange rate. Would come out in the neighborhood of £4700 with no import tax.

#17

Thanks Ape, still alot but that’s more within range of consideration. I’ll fire you an email over and if you have some options that would be great.

So far I found ECS ones and was looking at RS6 ones as quite alot of RS6 here in UK in salvage yards

#18

Sent you an email!

But to clarify for everyone else who may read this post, that price is for a PAIR of rotors, not each, so about 60% the cost of new OEM CCB discs. The ST rotors I offer are at a lower cost yet it’s a far superior disc in every measurable performance parameter with a wider selection of compatible pads to dial in your preferred braking feel.

Yorkshire_mick, when looking at the C5 RS6 rotors and pricing, make sure you are looking at cross drilled ones, they make them in non-cross drilled.
If I had the money right now I’d definitely go with Redmist Carbon replacements, a set for my RS5 and a set for my RS6. But I’m engine shopping and retirement house shopping so in other words I’ll be broke soon enough.

#20

I’d love the ones from Ape but money is the prevention on that.

Steve on here mentioned his Reylands on his and they seem around price I was hoping. I think I’ll likely go with them.

But priorities first, stage 2 from Ape is what I’m hoping to get first and hopefully soon now. Then I’ll get brakes when I need them more :grin:

#21

Oh man, I JUST sold my Reylands in the UK. I purchased a set for measurement purposes and had been trying to sell them for a year, LOL. Were brand spanking new at a discount but an RS5 owner in the UK just purchased them. They’re a very solid option and home grown so I’d go with them.

And just to clarify Mick, you have 8-piston front calipers correct? Black in color?

#22

Correct black in colour
