new rear op?

[0verkill]

im looking to get a beter rear now befor i get to big power numbers. im looking at the moser 9 inch but dont know what kind of godyes i sould put in it. i drive my car on the street most of the time but like to go drag racing and my want to auto cross a it next year. i want some thing that isnt going to hert drivability but i can put slicks on at the track and not need a tow home. so what parts should i look to put in it? my car is a 2001 ta m6.

m9 is the way to go to feel safe. 4.10 m6 3.73s a4 if you want a multiple task vehicle.. track, course and street
