I purchased a set of Z06 Motorsports a couple of months back. I torqed the nuts to 100 ft lbs at 20 miles then again at 50. Now I check them everytime I drive. Seems like there is always one nut per wheel that comes "unsnugged" and needs to be retightened. Is this normal or am I doing someting wrong? I also read something about Gorilla lug nuts and would these help the situation?

Not sure of the reason why they are coming loose, but that is not a normal thing to happen. Is it always the same lug on each wheel that is coming loose? Have you checked the lug studs to see if there is any damage to them?
The bolts are in perfect condition...first time the wheels have ever been off. One thing I did notice it seems to be the nut that takes the lock to get it off.
Make sure the lug nut is not bottoming out on the stud. This happens quite often with aftermarket nuts.
Remove lug nut and look inside for scratches on the closed end where the lug could be hitting it. If so, replace ALL nuts with stock or better fitting nuts. If they don't seat against the wheel before bottoming out, they're useless and dangerous!
