Used them and continue to on my 90 RS convertible. Don't be surprised if you don't get the claimed 1" drop. That spec is comparing the height to stock new spings. Yours are likely already sagged from age. Otherwise I'm very happy with them.

Re: eibach pro kit springs?
If its possible for anything to sag on a firebird than im positive mine is! Its had a hard life but im slowly nursing it back. If its close to an inch im not worried. Im not looking for a real low look. Just sporty with as good handling as i can afford to give it. My car has cragers right now with real big tires. I thinkn they are from an suv. Its what was on it when i got the car. Im planning to put the hawks 17 inch mesh reproduction wheels on it. Im sure removing the giant tires it hase will make it look MUCH lower

Koni yellow front struts, hands down. You would have to spend a lot more money to do better.
I use some moderately expensive double adjustable shocks for the back. And they probably wouldn't weather salty roads either. Not sure that's of Interest to you?

Re: eibach pro kit springs?
I put them in my 1989 Iroc and front end came down about 3/4 of an inch and the rear did not change. I had the original springs in there so they where pretty shut. I also installed Koni Yellows and IMO it rides better, but again this is subjective. On the handling side, it is much better now, and I feel much safer and the car is much more predictable.
