There are a number of threads about lowering the C7 on the forum. Personally, I'm not willing to give up any more ground clearance on a car that's routinely driven on public roads, into shopping center parking lots, driveways, etc.
I have dropped mine the full amount (1") on stock bolts and still have enuf room to clear anything I have run into, including speed bumps and any parking ingot. YMMV....another member's car dropped just like mine, also with Lashway splitter:
When lowered, especially with a splitter, you tend to learn to take steep drives, dips and bumps at an angle or risk damage. Not a big deal, and worth taking away the 4x4 effect. Stock bolts are sufficient.

While the lowered look is great, just be sure the roads where you drive are not so bad that the car ends up scraping the pavement. You also have to be aware of steep driveways, speed bumps, etc.
I don't think you can realistically lower the C6. Can you the C7?
Both can be easily lowered on stock bolts. However, I think you're possibly right on the C6, at least my C6 which has not been lowered, scrapes the air dams all the time on things that don't scrape on my unlowered C5 or C7. The C7 seems to have the best clearance of all for the driveway curbing and other areas I commonly drive over. I'm not a fan of the lowered look and the issues resulting from lowering.

One nice solution is to lower it about an inch on the stock bolts, then use masking tape and snips to trim one inch off the stock rubber air dam pieces. Looks good and no more scraping than stock. Just be sure to approach ramps from an angle.
My C5 and C7 are both lowered as far as possible on the stock bolts and it's definitely easier to get the C7 over speed bumps and up my challenging driveway without scraping. I think my C7 looks lower than my C5 but I think it was designed with better obstacle-clearance in mind.
One of the features that seems to help is the swept-back nose section of the C7. It allows you to crabwalk closer to a speed bump or ramp so the tire can start up the incline before the fascia hits. also, it seems the lower surface of the C7 front fascia is angled down towards the rear more than the C5 which helps. The front air dams on the C7 are also shallower which keeps them from scraping on an incline as much as the deeper C5 dams do.
The first time I drove my C7 up my driveway I cringed waiting for the usual loud scraping sound of the air dams and I heard . . . nothing! I think I may have heard a minor scrape on the C7 once. It's much more incline-friendly.
