Just saw this:
"Note: This coil-over system will lower the Corvette at least 1.5" lower than stock. Not designed for stock ride height"
They are not adjustable enough to get it back up to stockish ride height?

I don't see a valve for adjusting dampning/rebound?
By "single adjustable" do you mean only the ride hight is adjustable via the spring perch?
Any info on what the f/r springs are rated at?

You don't see the selector **** right there at the base of the coilover housing, front and center? Unless I'm fooled, that looks like a definite access point that wouldn't require tire removal.

I'll blame it on my tiny iPhone screen and not my tired ageing eyes.

I have the answer from QA1 on the height issue
Here is thier exact response:
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.

This is odd though. This response makes it sound like QA1 advises AGAINST lowering your car MORE than 1", but their website states, exactly as quoted,
"This coil-over system will lower the Corvette at least 1.5” lower than stock. Not designed for stock ride height."
So, from the above response, the MAX ride height will be 1/2"-3/4" lower than stock, but they also advise not to lower the car more than 1", making the adjustable ride height range less than 1/2"? Then, their website claims that the ride height will be AT LEAST 1.5" lower than stock?
What am I missing here?

-also- Haven't seen any details on this so have to ask ...
Would I be correct in assuming these replace stock leaf springs?
-and-
Are they a simple bolt-in replacement for current shocks?
Thanks!!

You are correct. You would remve your leafs and bolt these in as simple as a shock replacement
