This is out of my '73 AIM, should be close, no? I'm sittin' 29 1/2 fr and 29 1/4 rr, that way when I bought it, and would sure like to get mine to stock specs.

I have air shocks on my '76...it has tubes connected to a valve stem that is mounted on the bottom of rear bumper...Its tag says "minimum pressure 20psi maximum pressure 200 psi"..I do not know what brand it is..I am planning on replacing my rear spring soon due to it sits straight across..I think it should have a "bend" in it if it is in good condition...My ride height seems to be OK...I know in the past the older air shocks would raise your rear end..A buddy of mine had them on an old Monte Carlo..put to much pressure on them; had too much of 
..then blew one side(hit BAD hole in road)...glad I was'nt with him..right rear of car was sagging after that..
......Had a question are the fiberglass springs all they are cracked up to be for the price???.....Pete

Reason is heights vary depending on how vette equipped from factory...
Your 28" can be considered stock height..
My front(78) is 26.5" with half coil cut off from springs.....

I put Bilstein Gas Pressurized shocks on my car and it DID raise the height of the car by about and inch or so. The car has not settled down in over 10 years! I love the way it drives as compared to the stock shocks!

My 1969 Chevrolet Chassis Service Manual gives the specs for the front suspension height in the Front Suspension section, and describes how to measure it. I think it also gives the distance from ground to the bottom of the frame at various locations in a different section. There is no ride height spec given for the rear susp. that I could find when I made my first reply to this thread. When we finally get home, I can scan and post the '69 specs., but I have no idea if they are correct for other year models.
My Chilton manual covers '68-'73 and makes no mention of ride height at all.
IMHO, if the ride height is too high, for instance, unless you have a full alignment done at that height, the rear camber for sure, and possibly the rear toe, and front toe, camber, and possibly castor will be off.
Cheers,
Pete

Sorry for the long silence, we were out of the country for a week, and still aren't home where my resources are, but I can tell you this from memory.

Pete, Thanks for the reply... Im going to get a few more books here in the future....I only have the Aim and the Service manual.
But I have read on another thread that my height isnt that bad.
Its about 28in give or take a 1/4in here and there.
The ride is great though.. If anything I have more room for more tire now.
But I am still looking for the correct specs on the ride height.
Thanks again
George.

Sometimes pic's help....
This pic was taken in 1979 all stock factory height...front fender well lip at 28"....
This after lowering vette approx 1 1/2" (cut front coils)..front fender well at 26.5"...
New/old bushings can affect ride height somewhat...but not much...maybe 1/4"-1/2"

Now don't look at my '73, 'cuz the rear rides too high after a (dumb) "upgrage" to glass mono-spring (don't get me started!), and now the front rides too high after a front end rebuild and removing alot of weight (A/C, "upgrading" to AL radiator)...so now the whole thing rides too high!!!
But I'm looking at "fixing" the springs front and rear, because I thought this really was what controls ride height. Right???

Shocks have NO discernable effect on ride height, anybody with 1 year of high school physics could tell you that. Even the gas charged ones,, as an example, get a gas charged shock, compesss it in, feel the force,, what is it,, maybe 20 lbs of force?,, so the car weighs 3400 lbs, and the shocks are forcing back, say 80 lbs. how much difference do you think that's gonna make,, well it's not really that simple because what that 80lbs is working with is the compression rate of the springs. But go aroun to each wheel and pull up with 10-20 lbs of force,, and see how much the car lifts,, simple as that,, It ain't 2" Sally. 1/4" on a lucky day. anyting else is absurd.

At the most .25" if that and only while they are fresh. Once they have a few miles they will settle.
