I have a Spartan auto locker in front and a limited slip in the rear of my 8.8 I repacked the LSD and added.a few more disks. IM very happy with it the on road driving is like a open diff and wheeling I would have to say I get about 90% traction of a full locker. I think a good LSD has it's advantages for a multi use rig.
This is the way I'm leaning. I've got a LSD in my 8.8 as well (I used the beefed up racing LSD rebuild kit), and plan on dropping a lunchbox locker in the front (either a aussie or spartan).
