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

[Big Lee M]

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.

i hope this are the right ones? i cant find the whole part numbers on them...

[Skull]

here you go Ben

[s2avant]

They certainly look to be the correct setup. The discs are an older number but they are 300mm S4 rears. Do the carriers have any numbers cast into them?

Ben

[Skull]

yes they have something, but nothing like the audi part number:

[s2avant]

I'm confident they are right. The brackets and calipers look correct. Next job is to get them fitted.

Little reminder: Carrier needs small grinding job to fit.

where exactly?

[Skull]

cleaned one caliper and bracket. here are all the numbers i found...

bracket:





caliper:

[Skull]

wow, it looks like they really just bolt on.



and i found out where is the ginding needed

[Big Lee M]

When I had mine fitted there was no grinding needed. It seems some need to be and some don't. Good find by the way Skull.

[Skull]

yes good find, but it was far from planned. now i will have to live with bread and water for a month. that is good, i will improve the power to weight ratio

also with the pads in it fits like it is meant to be. i will make the shield usable too
