Serious rear wheel hop when I punch it in first at low speed.

Tires are cold... I would bet it won't do this when the tires get heat into them. That has been my experience with tires in any event.

That must be some serious hop if it caused you start the same thread twice! 
On a more serious note, wheel hop is nothing new to Vettes. There are a couple of ways to fix it - none of them cheap

wheel hop
I agree that cold tires at the threshold of traction are the problem. Warm weather will fix it. However if it persists a common effective solution is to vary the tire pressure between your back tires by 1-2 psi. This allows the tire that has the higher pressure to act as a fuse-able link and spin before serious wheel hop and axle/diff breakage occurs.

(For the record, I did replace the OEM tires with Michelin ones, but I seem to remember the issue going away when I replaced the shocks, not the tires)

George,
I'd check the tire temp monitors via the performance display. You get there by pushing the left arrow on the right side of the steering wheel, then scroll up or down to Performance, once in that menu, scroll down to tire temp. Your tires may be warm but not likely completely heated unless you were driving the car for a while on really warm roads or through a canyon. It could also be that the traction management is kicking when the tires start to spin causing a hopping sensation.
What mode were you in? Eco, Tour, Sport?

Actually, on my C6 Z06, I was able to fix it by replacing the stock shocks with special-valved DRM Bilstein ones which DRM had multiple group buys on. All things considered, it was in my opinion a very cheap way to get rid of the problem!

George has Magnetic Ride Control on his car. Swapping shocks probably would not be a great option for him.

Sport will definitely stiffen up the suspension. How long were you driving the car for when you noticed it? I'm still leaning towards the tires not being hot or perhaps the road surface or even traction control kicking in to prevent wheel spin. Wish you were a bit closer so I could see what you are experiencing. Either way, I'd bet it's nothing. You could try to decrease your air pressure a bit but before doing that, I'd check the pressure when the tires are cold. It could also have something to do with one tire being at 30 and the other at 32 which may cause the electronic differential to act weird.

Incidentally, I just checked my pressure and my rears are reading 34PSI and they are warm. Not hot. I'd suspect you tires may have been cooler than you think but I could be wrong.

I have had wheel hop on many of my cars in the past. 300ZX Turbo, my old 78 Trans AM, to name a couple. Although, it seemed sporadic. Could be temp related, but I do seem to remember on my Z it was due to a bad stabilizer bar though.., and my TA had a welded rear.

I never turn off any nannies, including traction control, on my Z06, yet I can spin the tires to 90 MPH in second gear. I just don't spin them as much as I would if the traction control was turned off.
On the ZR1's GM fitted them with half shafts of different diameters to help with wheel hop.

No, you may be right, Scott. Both times I had driven only a few miles. However, I've never experienced wheel hop before today.

If this suddenly just started up, I'd be looking for loose parts or maybe a tire problem. Given that the C5 and 6 had the problem and the C7 is so similar, I guess I'm not surprised, but I was thinking they more or less solved this issue.
