I was looking at this yesterday, and I have a few questions.
I can see where the bolt is in question, however, it looks nothing like I thought it would. It looks like it's threaded from the bottom, and the top pokes through the suspension and has a hex 'head' on it.
So, before I go and do this, I want to be sure the definitions of tighten and loosen. When you say "loosen", I think you mean turning that part sticking up to the left, but because we're looking (and tightening) the bolt from the wrong end, what we're really doing is tightening it, correct?
So, to the unwashed masses, it appears to be loosening the bolt all the way, because eventually, the real head on the bolt stops it from turning any further. But, to someone like me who thinks about these things way too much, we're actually tightening the bolt, and not loosening it.
That seems to be correct, but again, maybe I'm overthinking this, and I really am supposed to loosen the bolt by turning it to the right. But then this begs the question I was wondering since I read this thread -- if we're loosening the stupid bolt, what keeps it from falling out completely?

On the C5 there's a little clip that is on the edge of the bolt to prevent the nut from coming off.... but once it's under load from the weight of the car it shouldn't turn.

You can only go so far with the factory spring bushing in place. We made a bushing for the adjusting bolt out of poly. You should not need and alignment, the Corvette is a Zero bumpsteer setup, but since it is mass produced it would not hurt to have it checked. If you keep a watchout on our web-site we will also have HD bumpstter kits available for the front and rear coming soon.

I haven't check a C6 yet for bump steer, but the C5 does bump steer and definetly requires a 4 wheel alignment after lowering. FWIW - Most GM cars toe in after lowering.

If I turn these bolts counter clockwise to bring the bushings up against the springs... How much will it drop the car from stock. Approximately?
I also saw where the busing can be cut or removed completely to lower the car even further. I want to drop mine about an inch and a half.

Aha! That was the bit of information I was looking for!

Ok
YUP, its me the newbie again, SO, on my base 2006 c6 with stock 18's and 19's on it and stock tires, WHAT do i need to do to lower it without buying different bolts. Do I keep the front tires on, open the hood and simply turn that mysterious bolt counter clockwise and on the rear where is it located and what would i have to do? If you cut the bushing to get it lower, is there still a "stop" on the bolt or do you just trim SOME of the bushing? Do I need to take ANY of the tires off to do this? IF I go 1 size larger for a rear tire on the new rims (stock size) I just bought but have not bought tires for yet, will they rub or will the front rub at all when hitting the backroads or parking lot courses? Sorry for all of the questions, but every day I find something new I want to do to it and this sounds simple and helps with aesthetics. i dont want it "slammed" but lowering some would look good. Thanks for your patience!! Also, mine is ALL black and my new rims are all black, I just bought the red caliper covers, would the red racing stripes on the left side fender look gay and add a small red jake sticker on the halo on both sides or should I stay all black?
