When I did my RS2/993TT brake conversion, I went through the same
machinations. I remember that there are a couple of issues with using
the Audi parts.
a) You want the same diameter as the Porsche rotor. This is 323 mm.
b) the Audi rotor is slightly (1 or 2 mm) offset as compared to the
Porsche rotor. It doesn't mean much until the end of your pad life,
when the worn pad can slip out of the caliper.
I have the RS2 brackets, 993TT calipers, BIRA hats and use the real
993TT rotors. No problems whatsoever.
