Definitely use relocation brackets if the car is lowered. Pinion angle has been debated countless times due to difference in measuring technique. Honestly after f-ing around with it on the street and at the track I stuck the gauge on the TA mount by the rear end
turned the TA until I saw -2 on the gauge (front of pumpkin facing downward slightly) and that was it. This resulted in less road noise and helped me to achieve the ET/60-ft in my sig. Of course the TCI 3800 amd MT DR's did most of the work. :)

thanks - should have said it's not lowered at all.
With my 10 bolt (and the 9" in my 71 Lemans) I also set it at -2 degrees. I never tried any other angle...
I guess I'll stick with that and hope with the 12 bolt now my PT4000 and new ET streets will get my 60' down. And still be street friendly with drag radials ;)
Anyone having success with a different setting?
Without relcation bracets?

I run -2 and LCA in bottom hole of the relo bracket.

My car is not lowered and I run Spohn relocs on my Moser in the bottom hole. My pinion angle is -3, works for me! I think the M6 cars run a bit more negative angles than the A4 cars do, but don't quote me on that!

I have an m6 with lca brkts and bmr trak pak with the pinion angle at -2
it wiped out my pinion bearings. I called moser and he said that was to low for an aftermarket torque arm they sug. 0
