thanks for the reply . unfortunately i dont know the pr number . i have been wanting to do the 312mm brake upgrade for a while now ( at the moment i have 288mm discs ) and have been told a few times that i need the brake carriers of the 3.0 petrol a4 . these thing are as rare as hens teeth but last night i found a pair of carriers and calipers on ebay off a 3.0 b6 a4 . i just wanted to make sure that i have the right ones i suppose i will just have to wait and see (fingers crossed)

From the EBC website, they are 312mm. Happy fitting, now to find some myself.

well the carriers and calipers turned up and i have to say they look a lot bigger than the carriers i have now so i think i will be ok . also included unbeknown to me was a virtually brand new set of genuine audi brake pads fitted to the calipers i wish i had known this i could of saved some pennies because on the same night i ordered some EBC ultimate pads from ebay . i also managed to get some brand new genuine audi 312mm front brake discs . so tomorrow is the day they all get fitted i will let you all know just what an improvement if any there is

Can you see a part number on the carriers? If you would be kind enough to post it on here, i have been trying to source some.

This is a very common conversion over here in the US. You can actually just use the caliper carriers and larger rotors while re-using your own calipers. The whole OEM BBK is only 349.95 USD. Click here to order the whole conversion, currently 17% off.

If you want just the carriers: Click here.

I read that the carriers from the TT and A3 based cars (Gold, Octavia and Leon) didn't fit as the hub mounting points were different. Hence looking for ones from a 3.0 petrol or 2.5tdi.

Is this not the case???
