View Full Version : TT carriers: which ones for upgrade

12-17-2006, 04:15 PM
If one wanted to do the A8 rotors and TT carriers on their 1.8T A4 which ones would they get? I have a GTI 1.8t and need to know if these are the same ones i need to be able to upgrade them on mine.

312mm Audi Caliper Carrier 8N0 615 125 2 EA

Is that the same part number that A4's use as well?

I realize i need the Audi TT rotors as well, same bolt pattern, instead of the A8.

Yes you need the tt carriers, not sure of the part #... the A8 carriers have a wider bolt pattern to bolt onto the knuckle. I had the TT setup on my MK3 Jetta and it required a spacer for the caliper pad carrier to make up for the difference in offset of the rotor. But I think the MK4s don't require a spacer?
