turning a C4 into a GT
My DD is a turbo Audi. It's a great handling car for taking turns in a consistent and controlled manner. It's very quiet, great in the snow, and it can be somewhat quick if you push it hard enough. It's wonderful to drive - but it's rarely *fun* to drive...
Each one of the 3 Vettes, on the other hand, can be felt through everything they do. You feel the suspension working. You feel everything in the road as the tires channel their way through ruts and uneven areas in the road. In the LT4, I would hear the gears meshing in the manual trans. As I corner, my position in the vehicle sometimes makes me feel as though its' rotational axis is aligned with my hips - adding the the effect when I keep my eyes fixed to the apex of a turn and let everything follow to get me there. And, I swear I can feel any of their frames spring a little when cornering hard over imperfections.
It's this cacaphony, tactile, and inertial feast of the senses that make these cars the last thing the General built, in my opinion, that forces the driver to become part of the machine - to conquer the road. They provide a visceral experience that's affordable and - as I found out when I crashed my '96 - pretty safe. When properly maintained and not abused, they're also pretty reliable.
All this is to say, I think you're barking up the wrong tree with your intended goal. But, you might also be very pleased at the unintended treasure that awaits your C4 purchase!

It's much more comfortable than my daily driver Imapla SS.
The Best of Corvette for Corvette Enthusiasts


The closest you are going to come to that in the C4 is a '95-'96 as they are the most refined and "softest" of the C4 suspensions. If you leave the stock exhaust on it, or at least the mufflers it will be "relatively" quiet, in terms of "sports cars". You could then add some dynamat to the floor and cargo area. But you are still going to get wind noise, engine noise, and you will still feel the road, as you should in these things.
Depending on your budget, and your taste, of course, the newer the generation you go in a Vette will be the closer to that Caddy. As GM refined the platform even more with the C5 and even more with C6.
But you are not going to get a C4 to have that power and that ride and that quiet. It just can't happen because of it's genetics. Just not designed for that. Actually it's designed to be the polar opposite. That said, I like my "bone jarring" loud, rumbly C4. But then, when I bought it the first thing I said to myself was, "it's too damn quiet". So, to each his own, I guess.
I do not think it rides too rough.... but I do tend to know what towns have the bad roads.

He is right. EXCEPT, compared to both he C4 and the V, you will loose a bunch of visceral feel w/the C6. It is boring to drive, by comparison.I have recently or currently owned a C4, C6, and a V. The V combines the excitement, visceral experience, sound, steering precision, and seat support of the C4, with the sophistication, rigid frame, and poise of the C6. The V adds better shocks, brakes, stereo, interior quality and comfort and a stiffer frame than both the others. It's the best car of all three, by far.
As for making a C4 "act" more like what you're looking for IMO here is the recipe:
*Every frame stiffening product made
*Best shocks you can afford
*most sound deadening you can stuff under the carpet
*All new and the best weather stripping combined with proper install and fitment.
*Best brakes you can afford
*A complete stereo upgrade
*Removal, siliconing, and re-installing of every interior plastic item (for rattles)
I have monroe shocks on my FE1 sprung car and it is pretty cushy for a vette. Most people are put off by the extra body motions at 90 mph, but it still holds the road. If anything, it tames snap oversteer because the tires are not instantly overloaded. the suspension load up is more gradual.
Like Tom400CFI said, they feel sharper, the interior is (IMO) nicer, the brakes are better, the ride is both more controlled and smoother. The overall grip is lower for me vs my C4, but it may be because of the RS-A tires on mine. They have the same power/weight as an LT4 C4, and of course they can carry 4 other people.
Though as other people have said, the later C4's are much more "GT" with the softer suspensions and slightly quieter bodies. The ZR-1 seems to me to be clearly designed as a GT car. It was loaded up with features (for the day), horsepower, and an adjustable suspension.

I chose the C4 because it's still a car that I can work on (sucessfully, that is).
more specifically, I got a '91 because that's the last year for the regular small block (ignoring the center-bolt valve covers...).
and the 91's got the newer body style and the modern dash.
and even with this vintage, you need to be electronically qualified to keep it running. I now know how to datalog and burn chips, by necessity.
with the cars being sold nowadays, good luck with working on them yourself. last time I bought a factory service manual for the old lady's 2004 vehicle, it was like the encyclopedia britannica used to be (before that went the way of the dinosaur). chrissake, the service manual for my 87 Grand National was bad enough.
cars being built nowadays are not meant to be "serviced by owner" anymore. they are nice to drive, good for about 4-5 years, and then replace.
that doesn't describe the guy with the C4. okay, "person" with the C4, no gender-bias.
