Default Any rear brake upgrades good match for A8 fronts?

I have the A8 brakes up front. Sunday we went on a fast drive. When we stopped, my rear brakes were smoking/steaming and stinky. The fronts were fine. The rears are OEM rotors and EBC Greenstuff pads. I'm concerned that the rears aren't up to par with the fronts. Should I be concerned about this? What are my options? I didn't really find any valuable info searching. Keep in mind, money is a major restriction as it was with the fronts.

Rear disks/calipers from the B6 3.0?

Default From what I have heard, rears are not that big of an issue...

Since most of the braking is done with the A8's up front, and a very minimal amount is done with the rear, from what I have heard upgrading the rear is not really worth it. I mean, you can put some slotted rotors/SS lines to help reduce fade/heat and improve bite, but not even that is gonna stop the problems..

I've heard the same thing, which is why I was so surprised they got so hot on the drive Sunday.

Default Ugh. It requires S4 rear calipers. I supposed I could find them at a salvage yard....

...but would really like something as easy as the front A8 upgrade that only requires new carriers and rotors. I guess I'll talk with Champagne about it. Maybe if I use a different pad compound on the back it'll help even out the temperatures?
