I have the answer from QA1 on the height issue
Here is thier exact responce:
Our coil-over units installed on all four corners will lower the car about 1/2" to 3/4" even at maximum ride height. In other words, they will not return the vehicle to stock ride height. The stroke on these units is very short (regardless of who manufactures the parts) so our recommendation is to limit lowering up to 1" lower than stock and no lower. While some people want to lower even more, any qualified handling and suspension person will tell you that going lower offers no improvement in handling, messes up the steering geometry, and creates alignment issues especially with camber.
Frankly the most important factor is corner weight both the C5s and C6s after any change in ride height. For proper handling it is imperative that the corner weights on both the front left and right sides are equal. I see a lot of guys talking about measuring form ground to fender lip or ground to jacking point to "balance" the car. While that may give them the "look" it doesn't maximize handling the way corner balancing does. Simply put, with the roll center so delicate in a Corvette, when you raise one side of the front it is transferring weight diagonally across the car to the opposite rear and vice versa. If the fronts aren't balanced the car will turn easier in one direction than the other in handling scenarios.
To answer your question directly, lowering the car much more than 1" will allow bottoming out depending on road conditions and type of driving being done.

I've had most any kind of adjustable shock style you can name, and currently have two cars with coilovers.
For normal street use and a "cool" look, the advertised units should be fine.
For any kind of autocross or performance work, get the double adjustables. The advertised ones adjust both bump and rebound with a single adjustment. I've had that style, and you really don't have the fine tuning ability you need.
Separate bump and rebound adjustments are much better to tune the car for each condition/track.

anytime you have more variables it give you that extra edge to adjust your setup
