Any thoughts on bolt on compatibility??

Just now checked out the C6 RS6 390mm discs v D3 S8 and interestingly some critical dimensions are the same. Both are 36mm, overall depth is 59.7mm, centre is 68mm, both PCD 5/115mm.

Can't tell if that extra 2.5mm will touch the S8 caliper, and whether the C6 fixed 6 pots v the D3 twin pot floating caliper makes a difference

I would imagine the rs6 6 pot calipers would be an upgrade. Given that the lambo and other sportier cars run the 6 pots.
See i dont wanna pay out for discs and pads at arou d 600 - 700 if i can add a little bit more for maybe an upgrade. Id seriously look i to the rs6 kit as they also ran a 5.2 v10.

Main dealer are pretty useless and know next to feck all. Was in yesterday asking questions such as what can i bolt on from other models. The guy just looked at me in horror!!
He said just ate oem discs. Lol

Not that a 390mm disc would benefit. Its purely for looks as you can see the standard 385mm disc doesn't use the whole braking face of the disc. I could even likely go down to a 380mm disc without issue and use the whole disc surface.
might be an option in fairness. Has anyone put smaller discs on?
