Unless you change the carriers or possibly even the calipers aswell, I think your pretty limited mate. The S4 rear conversion cost me £260 all in. Fronts cost £540 all in.

I thought the 3.0 tdi had S4 size discs anyway? Happy to be corrected though/

If they have 300mm vented rears mate then you would be correct. I thought they had 288mm rear solid discs but I'm not 100% sure. I'll have a look on my dads.

Yeh let me know is it the same size on the B6 aswell?? Would they fit a B7 rear??
 
The 3.0 TDI discs are same as A4 Spec Ed 220 model all round i believe.... which would be Rear 288mm solid

I bought S4 calipers from a B6 mate.
The B7 is just a face lift B6. Loads of parts are interchangeable as far as I'm aware
 
Thanks. ..
So its the discs and calipers...and carriers needed??
 
Ahhh I notice from your signature you went to Rick for a map great guy loads of knowledge. ...can't praise his work enough. ..

Yeah he's most helpful and give me what I wanted safely aswell. I wouldn't go anywhere else now. Yet to pop over for the dyno, but no rush. My mates going over in his DTM to see him . I've also learnt a lot from him . Some tuners like to be a little secretive. It's the flat shift and launch control that does it for me lol!
