schrute

I've read what I could find here about Diff's but I'm still undecided on which one to get.

With winter coming, I want to get a LSD installed soon. The Z is my only car so on all but the worst winter days I'll be driving (will carpool with the wife in her SUV on really bad days). Yes I have winter tires ready to go.

So which Diff do you recommend for the following priorities (in order):

Quality
Price
Durability

I listed durability last as I don't plan on tracking the car much if at all. Mostly I want a LSD for improved winter traction and improved traction for spirited street driving.

The Carbonetic looks good but I'm not sure I need to spend that much.

Recommendations? Thanks in advance.

Edited to add: I don't have the sport package so > open diff. Not something I want to rely on this winter.
