Best differential for carving corners

[Greystang302]

I have no experience with the Power Trax locker personally, but I have heard about them from a friend who runs road courses. He said that they have a nasty habit of locking/unlocking in the middle of turns, and that this usually causes spins.

Just my $0.02.
