Definitely, turned bolt counter clockwise and bottomed it out, I even marked it and got approximately 2.5 to 3 turns.
Went over a ton of speed bumps and did some launches...
Didn't drop anything....
I hope it settles overtime...

Well it sounds like your car is already pretty much as low as it can go if you were only able to give it 3 turns. I think from the highest setting to the lowest setting and vise versa is about 30 turns more or less and it's only adjustable to about 1-3/4 inches so 3 turns would probably only equal about 1/8th of an inch.

I read most people get only a half inch on stock bolts...
Here is a thread I just read...guy states 2.5 turns of the bolt ...

Update: I just redid my rear portion just to make sure....and no way in hell from OEM stock height can you get 30 turns of the bolt. I got 3.25 turns and bottomed out and that is what I have read everywhere is the consensus.

Try this for a read; both C5 & C6 suspensions work the same way.

Not really, the procedure is different on the C6. Transverse leaf springs and adjusting a bolt but a different procedure for sure on the c6. THanks

Same basic suspension (transverse spring) on both cars; C5 & C6 both have the adjusting bolt under compression on the front where as the C5 rear bolt is under tension while the rear C6 rear works the same as the front of both cars.

It's a lot easier counting turns of the ratcheting wrench than actual turns of the bolt unless I were to put some kind of mark on the bolt and follow it from there but even then I don't think I even had enough light to see said mark if I made one. Didn't have anything to mark the bolt with when I was under the car though anyway so I just counted in ratchet turns. Not a very accurate way of counting but it worked for me.

Now that I think about it when I did my measuring of the "highest setting" I didn't go drive right after to let the suspension settle so when I lowered to the "lowest setting", went out for a quick drive, came back, then measured so that's why I measured 1-3/4 inch drop. I was measuring from highest setting, unsettled to lowest setting, settled which is why it was that much of a drop for me.

Also, the video I used to help me was the only video I think is on youtube on this. It really doesn't get much simpler than this vid.
