There is a video of a GM Engineer discussing how GM had the bolts there to allow adjustment. If GM didn't want owners to be able to do this, they would not equip the car with a way to do it so easily and then even comment on it in a video basically saying it is fine to do.
The change in height is so small, on a relative basis, there would be no impact on driving characteristics. As a matter of fact, I'm betting GM doesn't corner balance the car at the factory and the stock bolts would allow you to do that and IMPROVE handling if you were so inclined.

Same Dave now that I have my alignment done and looks so much better way to high before, thinking GM has them this high for drivers that do not want to worry about bumps and low driveways - that was the way it was with C6 so no difference now just be careful.
" Me too, Rich. I didn't buy it to let it sit."
Dam straight Buddy - time to go out and clay it now

Any slamming would probably be just the the shroud - air dams under the front bumper, in all my years in a vette that's the only thing I have had happen
Also we are only talking an 1" difference - that being said you have to be aware of that in your daily driving - no big deal Dave.

Please read gthal's comment above...THIS IS REALLY NOT ABOUT TRUE LOWERING...it is getting a better look with a 1/2 inch or so, because the designers allow the car to be corner balanced for the track...
This is about as far as you can get from mod cars that are bagged or coiled....

I do not track my car, although I do like a nice 1/4 mile drag - did many of those in my earlier days was a blast. These days they will throw you in jail just not worth it.

People make way too much about the very subtle drop. I can still get almost 3 fingers between the rear tires and the fenders... that is no where close to slammed or at all likely to bottom out.

I guess it is me again? After owning a C6 I probably will not lower the C7. Worrying about dips and speed bumps and the scraping sound of the front air dam always hitting (had to replace the air dam once) isn't worth a slight cosmetic improvement and that is debatable. At 180 mph the downforce should provide the lowered look some crave.

Some folks also need to remember that some cars have been delivered from the factory very low... as low as other cars after they have been adjusted by their owners. GM is very inconsistent with ride height.
So, if you happened to get a car that was a bit lower from the factory and didn't need to do it yourself, do you think there will be problems with lost air dams, rubbing, suspension issues, etc? I'm thinking not

just lowered mine this afternoon. all the way down on bolts. right rear is a 1/4 inch higher than other three corners but love the new look. will drive it a couple weeks so everything settles and will get all 4 corners evened up. have 1 1/4 inches between top of tire and bottom of wheel opening on the three corners. 1 1/2 inches on right rear so I hope it settles down on its own or I will find a way to get that extra 1/4 inch to match the other 3. car has 1200 miles on it. originally had 2" difference in front and that was way too high for a sports car look.
