It is not a difficult procedure as long as your adjustment bolts are not froze. Once you have the car up on jackstands you will need a bottle jack or some means to take the spring pressure off the bolt. then simply crank the bolt down with a 10mm wrench or socket. If the bolts are froze you will need a good penetrating lube to try and get them to release. Finally note and I do believe if you raise the front you need to also raise the back because of the rake angle the cars have. At least that is what I have been told.
Generally this situation is relatively easily remedied by adjusting the spring-height adjusters as suggested by the other posts. If you do make any significant changes though, might be a good idea to have the alignment checked as it can change. Also, as to the cause of the issue, consider that the age of the “newest” C6 is approaching 10 years old and the mono-leaf spring has more than likely settling over time.
Not sure what vehicle you have but the spec on a C6 GS is as follows. Measurements are from center of fender opening to the ground:
front 27.3" +/- 3/8"
rear 28.2" +/- 3/8"
For reference, my GS is 10 years old with 12K on it. The rear is right at 28.25" and the front is slightly low at 26.75. I'll attach a pic for reference from my phone. Hope this helps.
Nice - was looking for those specs. Hey, in your research, did you find whether GM recommends going a hair more on the left front, kind of like BMW does (5MM usually), so the car is perfectly level with the driver onboard?

I have not seen anything that would indicate GM accounting for the driver.
Thank you all for the comments and information...the adjusting bolts are soaking in a spray freeing solution...Blast. Lets hope it frees them up...if not I will have to live with it a while longer
Damn, I just went out and measured my 10' GS Vert and the rear is at 28", but the front is at 26". Perhaps I should just lower the rear an inch. Doesn't seem like I would have to do an alignment and I am already used to driving it with the front that low. Not sure if it was lowered in the front by the prior owner or if it just sagged that much. The car has 22,500 miles on it. Any opinions?

Depends on what you want. IMO, these cars are already very low so I would likely raise the front up ~.75". This would still put the front 1/2" lower than stock. You can use my pic several posts above as a reverence.
