I would imagine posi or locking differentials would be bad news with tracks, and you'd really want to install a braking system that would brake left or right, and still be normal with the brake pedal.. that way you could steer by braking like a cat does.. and all of this is null and void if you go with individual tracks per wheel.. ha.. thought about it and remembered seeing a jeep with a track setup on each wheel, only makes sense to do it that way.. (go back to sleep wayne)....
