The Z06 gears are shot-peened to make them a little stronger.

I run with the non-Z06 3.42 in a 2002 A4:
remember that the manual tranny Z06 has one helluva torque factor due to it having (and being able to dump) a clutch. Unless you go with a full race high-stall TC with drag radials... the Z06 diff should be more that enough.
(but this is free advice
)

No difference between the Z06 diff and the coupe diff. The trannys are different. The MN6 in the coupe and the MN12 in the Z. Not only are the mn12 gears a little stronger but they are also geared ALOT better than the mn6.
Gear LS1/MM6 LS6/M12
1st 2.66:1 2.97:1
2nd 1.78:1 2.07:1
3rd 1.30:1 1.43:1
4th 1.00:1 1.00:1
5th 0.74:1 0.84:1
6th 0.50:1 0.56:1
Gear LS1/MM6 LS6/M12

Ok, so that is why it's better to get a ZO6 3.42 over a C5 3.42 to use with the A4 tranny.

As far as transmissions go, I don't think that the MN12 ratios are better for my car, I've got a 4:10 rear. It would make 1st gear very, very low. I can start out in 2nd gear now without a problem. Can you explain how a MN12 trans is stronger?
