You could hear it if you were looking for it but not bad at all. Just change the oil every year at the end of the year. I used royal purple with no gm additive with good results.

best of a 1.53 but usually around the 1.6 range. I would rev it to the 3500 - 3800 rpm range and floor it after i dropped the clutch. You could hear it more at the end of the year but with a change of oil it would go back to normal. I tried mobil 1, regular 80w90 different brands all with the gm antislip additive and the only one that I found to work was royal purple without the gm additive.

This is a completely wrong statement. In my old 2000 camaro m6 with a 12 bolt that I owned for 4 years, put about 40,000 miles on, and ran consistent 11 second passes for most of the years and then the last year ran consistent 10's on 1.50 60's. I never had a lick of trouble with that 12 bolt. Then sold it to another person on this board 2 years ago and as far as I know he's never had a problem either. A eaton and auburn pro posi unit 12 bolt will be more then stout enough for a lot of people on this board m6 or a4.

Guys I apologize, I'm starting up another rearend gp for strange and moser. I didn't see the additional replies here otherwise I would've posted earlier, many have pm'd me with requests so feel free to do that.
As for the 12 bolt vs. s60 questions I try to stay away from 12 bolts in 6 speed applications because the 12 bolts don't have pinion supports and the stock of the clutch dump causes everything to more around in there which eventually breaks parts. I've seen plenty of 11 second 6 speed cars break 12 bolts.
