These are drilled:

But seriously that is all I found.

Just for grins and giggles.... why do you want drilled rotors?

MP4.2+6.0

If anyone has them, down to brakeworld.com...maybe. They seem to re drill OE and then seems to call them DiscItalia that you can find out nada about. Where my D3 W12 ones came from. I have been meaning to call but never got to it. They were straight with me on phone back in D3 era.

The pin nature of these makes them unusual animals. There are apparently no blanks available for the aftermarket refinisher shop types like Adam's Rotors to work on either. Emailed them already--even though on web site they say they have no idea where to get blanks. Honestly I had impression there that they really don't know what rotor is, or not enough business to look into it harder. Same question has been asked on AZ C7 S6/S7/RS7 board and same lack of info--more enthusiast than this one and same rotors shared by both.

.. and a little story I found about the company...
ROTORS8 - Stance Works

MP4.2+6.0

Nope. I e mailed with Adam himself a few months ago. On my S8 at 400mm. Honestly I don't think they understand what the rotors are, but he replied first person (and actually correctly AFAIK) they couldn't source the blanks to do the work. But on product side essentially inaccurate vaporware site for this specific application as a result, even if well meaning guys trying to make a business. And I know they can do them for D3, but those are standard and oh so heavy cast iron rotors. Net, don't believe everything on the web just because there is supposedly a listing for it.

On pics, unless those are like 22" wheels, that isn't a D4 S8 or a8 4.0T. In the legit S7 or D4 20" wheels like those, they should be polished (and forged) and rotor to wheel clearance is much tighter. I know...from running exactly those 20" wheels on my S8 and factory brakes. S5 or something down at 345mm maybe and then 19" painted wheels maybe, but those start as standard cast iron blanks, not the specialized A8/S8 quasi two piece pinned ones.

I believe the pick of the black car was an S5. That's too bad about being listed on the website and not actually being available. I was more upset to find out that the anemic looking real calipers can not be upgraded due to the integrated electric e-brake. My last AMG had huge 6 piston Brembo's up front and 4 piston Brembo's out back... Audi brakes look disproportionate front to rear.

Got these 380mm cross drilled and vented discs for my D4 A8 4.2 tdi. Working perfectly so far.
