I'd like to help but I don't know the thread pitch.
How about measuring the threads per inch and calculating from there.
I'm pretty sure the amount you move the bolts does not equate to the amount of drop.
I've lowered many C5's and C6's. The most I've heard or seen lowered on the rear of C6's is 2 1/2 turns. So you really don't have much calculatiing to work with. The front is another matter.`
Tell us why you need to know the thread pitch. I'm curious.

1 TURN = 2mm. Another forum member told me this and when I actually lowered it and counted the turns and the resulting drop, it worked out eaxactly.
Keep in mind that after you're done jacking the car and performing the mod and then lower it back down that you won't see the change (it may actually sit higher). You'll need to drive it at least 20-30 miles and then measure it. It takes time for the car to "settle".

Just a thought but there's no guaranty your car is setup perfectly from the factory (mine wasn't). Just turning bolts an equal number of turns may not achieve a properly balanced setup (the factory rake notwithstanding). Whenever you turn a bolt in one corner it affects the other corners...the one diagonally the most.
It isn't overly difficult but FWIW there are certain procedures to follow in the process of measuring and adjusting the height of the car.

Word of caution: I drove over deer carcus last weekend. The ensuing mess is not pretty. I could not avoid the incident as there was too much traffic on the interstate.
Car is low enough already IMO. Unless you really don't drive it much and it just sits no harm no foul.
But, beware. Remember the unintended consequences.
Also, I don't really like the lowered look.

You could drive over "deer carcus" with a stock height C6 and have the same result. Lowering your car would have no impact on that situaion. Vettes don't look right unless they are lowered. But... thats just my lowly opinion.

Don't count threads...just put in lowering bolts and lower it as much as it will go! Will you have rubbing issues?...I think it just depends on how you drive. I've got 44,000 miles on mine and not one single scrape on the front bumper or rocker panels. It's a daily driver and the only car I have. Haven't met a driveway yet that I haven't made it in and out of.

If you take the bolts all the way in you dont really have to do that. It will be the same in front and in the rear. I did mine all the way in took 20 minutes. Looks a lot better too.

Don't forget to measure at all four corners to make sure that your lowering is the same on both sides of the front and the rear!
I'm sorry but unless I don't understand this post it is just not true.
As an example your car might have come from the factory with 2 turns remaining on the left rear, 1 turn on the right rear, 5 turns on the right front, and 7 turns on the left front.
This is very close to what I had from the factory on my 2008.
How would the car sit if I would have turned the bolts all the way in?
IMO the most important thing when lowering is taking before measurements.
