Default Front end push?

When I turn my Z on loose gravel on black top, the rear tries to push it straight vice letting it turn. Is this normal?

When I turn into my gravel driveway off my gravel road it turns OK and does not try to go straight. I know the slip is not as noticeable on gravel but i don't end up inthe bushes.

I have Royal Purple gear oil in the rear.

If you're talking about about the front wheels skipping when close to full lock, like in a parking lot, that is a side effect of the Corvette's steering geometry. The way the front of the Corvette is set up, it cannot maintain proper Ackermann angle at full lock. It is well known and not indicative of anything being broken.

What do you mean "proper ackerman"? Does it go to pro or anti ackerman?

I believe it's anti, as the rack is forward of the spindles. At full lock, the front wheels will still be parallel, leading to this skipping over marbles situation.
