Since everyone one, well almost wants bigger brakes. We've discussed the 390mm C6 RS6 rotor but if you live in N. America they aren't easy or cheap to come by. Just a thought but the '07~'08 Audi S8 and the 2005 A8 W12 used a 385mm x 36mm rotor. 20mm taller and 2 mm wider and they are cheaper.

From Genuine's website. Anyone have access to one of these? 2mm would probably fit in our Calipers just fine. The 2005 A8 W12 also used a 335mm x 22mm rear rotor, same size as ours. Anyone know if it was a 2piece?

Listening...I think G2 should get some and test...for me, would really like more stopping from 100-0!

this would be a really good alternative, on another note, didn't some of the owners used the VW Phaeton W12 brake discs? cause i think they're the same as the A8, therefore they should fit...
this is how the W12 rotors/calipers look like: http://forums.vwvortex.com/showthread.php?2895052-Corrosion-on-Wheel-and-Brake-Components-Painted-Caliper
however it looks like there are differences between NA W12 and ROW W12 rotors, to me it looks like the ROW rotors would fit the RS6, but not the NA ones...

Are the 385mm front discs a floating design (2pc) like the stock rs6 rotors?

BTW, I doubt the stock wheels would clear these. Probably need 19's.

The fronts are a one piece and it won't fit unless you take about 7.5mm off the hub...
The one to which you are referring: '08 S8
