I'm lookin to rebuild my rear end for the upcoming mods I plan on doing. If I get a Moser 12 bolt with 4.10's on a daily driver will I be fine? Also which ABS package should I get, obviously it doesn't come with one so I have to get it seperate. There is a 3 channel and 4 channel.

 

the abs is a three channel, the tcs and abs is a 4. If you have a six speed 4,10 will be fine

 

If it is an M6 I would definatley go with the 4.11 gears. Notice I said 4.11 and not 4.10 gears. It is nothing that you will feel or notice it is about strength. I do not remember the exact number, but the 4.11 gears have I think 1 or 2 less teeth on it. This means that the rest of the teeth have to make up the difference in the circumfrance (sp??) of the gear and are therefore thicker and stronger.

 

A4 My other choice is a 3.73, but the cam I want to get requires a bigger gear.
