Hello,

I just bought a 2009 A6 3.0T Avant.

I am going to tune this car soon, but I am feeling that the OEM front brakes doesn't really cut it and I don't think a swap of pads will be enough. Recently did the Q5 Brembo swap on my A4 B7 and it has amazing brakes now, so I'm looking for something similar. The problem seems to be that there isn't a lot of people doing brake upgrades to their A6's(at least compared to the A4 community), so I can't find any writeups about it. Maybe I am not searching good enough. I have found out some stuff, but I need assistance to find out what fits or not. Can anyone help?

1. I read that A8 brakes should work on the A6 4F/C6 straight bolt on. Is this true or will it affect ET? There is an A8 setup that has 360mm discs and 2-pot floating calipers. This is a very cheap upgrade, the calipers can be bought for about $100 each new.

2. Some combination of RS4/RS6 calipoers/discs seem also to be bolt on? But Im unsure what part numbers. Does anyone know? A german ebay seller has been offering a kit like this for the A6 for a long time:

I know that there is StopTech and Brembo GT kits for this car, but they are like $4000. If I source OEM parts on the junkyard, I can find a pair of RS6 calipers for $5-600.

any input on bigger front brakes for this car is appreciated. I would prefferebly not want to use discs larger than 365.
