If you are looking for a cheap swap. I saw this on ls1.com.

Both the 12 and 9 are a great way to go. Do you already know what you want? Is money an issue? 12 bolts are nice if you have 3 channel abs.

Out of my region here but... 12 bolts are notoriously bad for m6 cars. A lot of people complain about gear noise after a few hard track launches. 9" or maybe even a strange s60 are probably better choices especially for a m6.

truth is they all can break. A4's can get away with built 10bolts and 12bolts for sure. But m6's really need a 9inch. Its all a guessing game wether yours will hold though you just up the percentage yours will hold by upgrading.

12 bolt is a waste of time on a M6 car..
I believe there is a red camaro by the name of LSgun who bought a moser 12 bolt for his M6 car and was complaining that the differential always leaked and howeled like a ****...
Taken from Bob @ EPP
"Put a 12 bolt into a early Chevelle, Nova, Camaro, etc and you can beat the crap out of it, and not hurt anything. Put one into one of our cars with a torque arm, make a couple 4000 to 5000 dragstrip launches, and I can just about guarantee you'll pick up gear noise. If it is a drag only car, you'll never know or care about the gear noise. Drive your car home from the track, and the noise will drive you nuts. I feel the torque arm stresses the 12 bolt housing, causing distortion. We have never seen this happen with the 9 inch housing..."
