Stock diff
How strong is the stock LSD in the rear end? If I plan on 400+ rwhp, should I go with an Eaton or Auburn posi? I know the 7.5 rear end T-lok is crap, but I don't know about the 8.8.

RE: Stock diff
From what I've read on here it sounds like the Ford Trac-Loc LSD is a fairly weak one compared to others. Once the clutch packs wear out I would look into a better unit like the Auburn., and swap out the gears while you have that pumpkin open., maybe 4.10s? 
My car is still fairly new, but if I upgrade to 4.10 gears in the future I will get a better posi too.
