I'm going to set up a redundant note here... but what gears are you guys talking about running...??? It makes a difference... I have to say this, because it's about the only thing I've done and can do... already updated my '06 GT rear with 4.10's and an Eaton E-locker... I would have liked to go with the 4.30's, but couldn't get a decent locker/limslip unless I went 4.10's or 4.56's.
Once I break the 8.8... I'll go BIGGER>......
