Looking to replace my 3.31's with 3.73's. But I was Going to replace the limited slip with an aftermarket setup. Best choice to go with? Torsen, lok, eaton,? Or stick with the stock setup on my 2012 GT?

stick with stock, why would you want to replace stock diff? these 8.8's are pretty solid axles. I would spend money else where

Eaton best for strength w/o penalty in road use. Auburn is good as well, as long as you can accept that if you damage it, it's not rebuildable. Detroit Locker is too noisy/rough engaging for a car that sees road duty, Torsen for road course work as long as NO drag strip duty is planned. Stock T-Lok can be shimmed tighter for increased gription + leave the fish oil out if you can stand a little chatter. I did that on an 8.8 and ran slicks at the track for 10 years w/o issue, behind a power adder.

Don't worry about this if you're thinking, "while I'm in there". You can add or change any of these at any time without resetting gear depth or anything.

I have heard and seen nothing but good things about the Eaton units.
