Just for the heck of it one day I thought I'd have a look at the audiusaparts site. So while there I looked up front brake rotors for my D4 S8 and was surprised to see the price of 400mm ceramic rotors.
Now on other cars I've owned in the past I've replaced front pads to ceramic to reduce brake dust but I'm curious to know if there is a ceramic rotor as they are listed at 4K plus each! Are they ceramic
coated or some kind of special alloy to use with ceramic pads?
Figured some one here would know.

Yes, ceramic rotors and ceramic pads are two different things. Ceramic pads are typically the lower dust type formulations like an EBC Red's.

Yes, there is a ceramic brake option for D4's. Came out with S8 Plus for USA in recent years. Has been in Europe back to D3, and often were found on W12's or S8's there. The ceramic rotors are indeed that same 400mm size used in the cast iron set up of D4 S8 or C7 S7. They are essentially life of car (like 300K kilometers), w/ pads still at normal intervals. And yes, the rotors are out of this world expensive. As between the brake calipers at 400 mm, they are very similar, but the ceramic rotor one has a slight curve/twist to it near the bottom, in addition to a sticker trim job. Both are 6 piston Brembo type, but ceramic rotor ones also have some heat related insulating stuff at the pistons that the conventional ones don't.

If you need to replace the ceramic rotors, can you go with steel and use the extra money for a jetski or do you need to replace with Ceramic?

If you did that, you have to change the rotors to conventional as well as then use a set of pads meant for cast iron rotors. Besides finding a conventional rotor in the same thickness and diameter along with hub center and bolt pattern and such, the likely practical problem is the brake pad. The ceramic fit ones are a different specific shape than the conventional ones are IIRC.

In addition, the ABS is set up for the specific brakes on the car. I think you can probably change that with VCDS--you could on D3. Besides amount of force and such, the ceramic set ups need to wipe the rotor periodically by applying the brakes very lightly when it is raining. Otherwise if you apply ceramic brake pads to a wet carbon ceramic rotor, it's push and pray as you count one thousand ... until enough heat builds up to get rid of all the water bits.

Newbie here. Does the Dynamic Package include both ceramic brakes and ceramic rotors on the '16 and '17 S8?

I just replaced all brakes on my s8 and I went with Zimmerman rotors and EBC red's pads , have around 300km on them and they are amazing . Best package for the money. CEIKA.com they custom build brake for S8 but the price is over 15k for all around, rotors, pads, calipers .....i better spend 15-20k to upgrade to stage 3 than just replace the brakes .....

Hi guys, I'm at that point with the ceramic discs on my 2009 S8 V10. My rear pads are totally gone and I'm contemplating the cost of changing front/rear pads vs putting in steel discs all round and selling the ceramic discs/calipers.

Is it a straight forward swap if I buy 380x38mm FRONT and 356x28mm REAR discs? How complicated is the reprogramming of the ABS and 'disc wipe' function that is used on ceramics? What other things do I need to consider when removing the ceramic discs and calipers? Any advice would be hugely appreciated!

How many miles on your car? I thought carbon ceramic rotors were good for like 200k miles.
