With the 256mm TT rear discs you need B5 S4 rear calipers and carriers. Theses are from a 2.7TT V6 S4. If you have B6/B7 rear discs(300mm),calipers and carriers they all bolt stright on.

[Skull]

with TT disks? what size? the s4 disks are not usable?

[Big Lee M]

are the parts from an s4 year 2004 any use for the rear brake upgrade?

Yeah that's what I have on mine. B6/B7 S4 V8 rear brakes are what you want.

are the parts from an s4 year 2004 any use for the rear brake upgrade?

[AndersS2]

the bolts im talking about is those four (4, 2 on each side), which bolts the carrier to the hub.

Just try it out for yourself, then youll se that none of the oem bolts are long enough.

[Lars Erik Johannesse]

witch bolts i need to use on the carrier on my avant?

[AndersS2]

You need Bolts from the S2, the S4 V8 Bolts don´t fit.

these s2 bolts are also not long enough. All OEM bolts my local Audi dealer could supply me with, were fact too short for bolting the carrier to the s2 hub.

I had to cut mine in custom length after finding the right size in acceptable enough strength (12.2)..

For the silver ones, yes!
A small difference in letter means a big difference in part! There is going to be a big difference in price as well unfortunately!
In the Forum's defence, all the information needed was in both the threads you have posted in.

[Lars Erik Johannesse]

its looks like i have ordred wrong calipers without the letters.

So the correct part number i need is following ;

8E0615423C
8E0615424C

And this is from a Audi S4 4.2 V8 B7 2006 age?!?!?!

[twoqu]

Hmm..
It looks like you have ordered regular A4 rear calipers (8E0 615 423/4) suitable for 245X10mm discs and not the correct S4 ones. The horizontal ribs are a big clue! As I said previously, it is important to get the letter at the end correct!
The part numbers are listed on the thread and above and very depending on the colour required.
