Suspension tuning

This is in a Z06?
Is it a gear type diff or what type exactly is it?

If you can manage to get the inside rear wheel in the air and be at full throttle, you are probably going to spin out no matter what type diff you have. It sounds like a guy who ran up on a curb on the track. I doubt you are going to have any kind of big problems. Most drivers naturally adapt to new handling traits a diff swap would create. Just work up to it don't go nuts the first lap and you'll do fine. It sounds like you are over thinking this, which is natural when you are waiting for the car to come back from the shop.

I drove a formula 5000 car that had a weisman diff, it locks on acceleration and unlocks when you lift off the gas, with a lurch to the left. After a short while, I didn't even notice it. I did have to have the front wheels pointed more straight when I got on it or it would understeer. Those cars have around 60% rear weight and huge rear tires, so rear traction out of corners is pretty huge compared to the front and understeer can happen more easily with a locker type diff.
