SWCDuke put up an excellent review of the 06 on the CF, C5 general section. In his evaluation of the car he tried to launch the car and test GMs 0-60 claim. He indicated that launching too soft would result in wheel/axel hop, and too hard excessive wheelspin, and that there was a small margin in between for a good launch.
I find this quite interesting, and I am always trying to find ways to a better launch. My car is lowered, max in front and low, but not maxed in the rear, and I found it has helped some, but not eliminated the problem.
The last time I was at the drags I had limited sucess until I starting spraying big shots of nitrous, and then it was wheel hop city all over again. I have a window switch, so the car was moving at a decent speed before the nitrous kicked in, but the addition of all that power was too much for the suspension to handle, and I hopped through first and second, resulting in a slower time that NA!
I think I need to try launching harder and slipping the clutch as someone suggested above. I haven't been able to break 2 second 60 foot times with my current technique
