Tire skipping
This will be the first high proformance vehicle I have owned so I am not sure if this is a common problem with a vehicle with wide tires.
When taking sharp turns at low speed the tires seem to skip like in my F250 in 4 wheel drive. Is this normal?

Actually, I had to get some stuff fixed on mine so I asked the dealership to check that as well as I was noticing the same issue on a nearly full-lock turn in either direction. They said everything was working just fine, and they checked it on a black Stingray that was there and it did the same thing, so it appears that it's just how things are gonna be. Just have to be careful with those sharper turns.

Page 10-62 of the Owners Manual:
Tire Chatter/Hop
When driving at slow speeds and in
very tight turns, the vehicle may
have tire chatter/hop. This is normal
and the vehicle does not require service.

I haven't seen anybody actually explain why this happens, so I'll give it a shot.
During a sharp turn the outside tire has to travel a much farther distance around the center of the turn than the inside tire. Both tires are turned about the same number of degrees because they are mechanically linked through the steering rack. Assuming that the outside tire is turned as far as it can go, that means the inside tire is not turned far enough and is sliding sideways across the pavement.
With a wide, grippy tire it becomes very noticeable as the tire grabs and releases like in a shudder.

^ That is incorrect - the front tires are turned at different degrees of angle.

It's not a matter of you're being wrong - just trying to make it accurate.
The width of the tires is the fly in the ointment. They are of sufficient width that the inside section of a front tire's tread is rotating at a different speed than the outside section of tread (depending on turn direction) so that the slower rotating tread 'skips' along the road surface.

^ I'm a bit lost on what you mean by 'fixed'? The more or less you turn the steering wheel the sharper or narrower angle of the turn radius.
Perhaps by fixed you mean that at any given point of a turn, the angle of the turn radius remains the same. regardless of speed of the vehicle - that is totally correct.

Melting Slicks
Note that this is largely caused by the stock Michelin tires. Since changing to the Continentals (same size tires) I have noticed little, if any any skipping/scrubbing. With the Michelins on, there was extreme skipping in parking lots and backing out of my driveway.

I experienced the same thing. I called two Chevrolet dealerships in Metro-Detroit. The service write guy at the first was clueless. I then talked to the Service Mngr at the other dealership and he was very aware and experienced of this issue.
He said it is not a problem but a performance tire and performance wheel alignment phenomena. He sent me the following:
PI1056A: 2014 Chevrolet Corvette Stingray New Model Features - (Oct 7, 2013)
Diagnosis
The Michelin® tires may exhibit a chatter noise during low speed tight turn conditions (i.e. parking lot, driveway, etc.) when the tires are cool. The condition can be experienced in all directions: right, left, forward, reverse. The condition typically reduces or diminishes when the tires warms up, but may become worse when the pavement is wet. For these unique and aggressively tuned high performance tires, this is considered a normal condition.
Inform the customer the noise is tire hop and is caused by the large amount of tire scrubbing across the pavement as the vehicle is turned.

^ Correct - the Continentals in the same widths, are actually 'skipping' just as much as the Michelins but their lower grip level does not cause the dramatic 'grip and release' effect of the Michelins - in other words they skid along smoothly
