400mm is rare on the 4.2TDI, only seen one fitted with them. Also used on the W12.

380mm more likely, PR code 1LJ.

See here for specs.

Going by the title isn't it for a S8?

Note to self, read the title!

S8 will probably be be 400mm! But the 380mm linked above is listed for S8 also, so need to check the PR code to be sure?

Right I've measured them following a pad change and what an interesting design! 400mm X 38mm and they are fully floating... they have aluminium rivets that hold the rotor on the hat...

Which is Audi’s patent I understand, hence nothing aftermarket off the shelf. I’m interested in why you want to get some made, to try to improve them?

It could be well cheaper than Audi OEM Discs.

I think oem 400mm rotors are around £300 a piece, not too bad considering
