Dog,
Front and rear turn the adjuster counterclockwise as you are looking down from the top. The suspension is the same.
There is no way anyone can tell you how much the car will be out of alignment or if it becomes out of alignment at all after lowering. If it begins close to being out of the alignment specs then it probably will be out of specs when you finish lowering. Have it CHECKED.
All C6's I have seen lowered only got about 1/4 to 1/2" from the rear from the stock adjusters.
The fronts were about 3/4". A good idea is to start with the rear then you will know what you are working with when you do the fronts.

I'm going to give it a try this weekend. I looked it over last night and it doesn't look that hard to do. Someone mentioned the shock adjustment. How does this affect the shocks?
Thanks in advance for all advise.

I got more out of the rear than the front. I'd say I got about 1/2-3/4" on the front and almost a solid inch on the rear.
Turned out great
I would not want it ANY lower as the airdam rubs just slightly when I back out of my garage now...perfect

not that i can notice.
i had mine done when they replaced my broken knuckle. i also have the z51 sway bars.
i asked to have the 'wheels centered' in their wheel wells. i'm not sure how much it was lowered but i used to be able to squeeze under her (with the tires on the ground) now i can't even come close (my head is just too darn big
). if i put the front on ramps i can't get under the rear without jacking her up.
i do rub the 'airdam' a bit more but not so much as to be an issue.

I hope you get that much from yours. I only got 1/4" (2 turns) from the rear of my 2007 and 2008. Had to cut bushings.

how did you cut the bushings? i attempted this the other day and it was a pain in the A$$ to do so. i gave up and left it lowered all the way on top of the bushing. the front lowered exactly the way i wanted it to. the wheels are tucked almost perfect in the fender wells with no gap but the rear i want another 3/4 or so lower. if i undo the bolt all the way out of the leaf spring how hard will it be to get back into the spring after ? im doing all this in my drive way and dont want to have to take off control arms and so on to do this.

It might cause your stock shocks to bottom out when hit a bump.

You would have to hit a sharp bump...I'd be more worried about the front of my car than the shocks at that point, lol.
And no, I have had no problems with handling. I went to the devils backbone a couple months ago and carved up a bunch of corners lowered on stock bolts...did just fine

There are many threads on the topic of cutting bushings.
Some have cut them with the bolt attached to the spring.
To answer your question, if you get the bolt out it is easy to get it back in. And to get the bolt out you have to undo some of the suspension.

I did the lowering the other night and got a 1/4" out of the rear and about 3/4" in the front. I too, did it in my driveway and it looks allot better, however, I would like to bring the back down another 3/4" or 1", as well.
I noticed there were two sections of rubber on the bolts with a metal plate between them.
Can only one rubber be cut out or does both have to come out?
