Rough Ride
I just bought a 95 C4 coupe my first vette. It's a beautiful but when you hit the slightest bump it's horrendous it's like hitting a curb with no tires sometimes i think something has fell off. Is this normal .Or are my shocks shot. Iv;e heard it's because they have a tight suspension.

Check your tire pressure. If they are over inflated that can cause what you're experiencing. Take a look at your shocks and see if they are leaking. See if your suspension bushings are dry rotted. Also take a look at your mono springs for obvious damage.

Replace the tires and shocks. (Bad shocks do not necessarily leak)
Check the roof panel bolts for torque.
Sounds like someone just cleared a spot in the garage waiting for the value to go up.
Now you own a car that has been sitting quite some time?

This will sound silly unless it's happened to you.
Check the rear sway bar to see if it's mounted correctly. It's very easy to install the bar upside down.
Look for marks where the bar is hitting the frame.
Another way to do this is to simply remove the rear bar and see if the ride is different.
You just never know with these old cars.

We just got a 1992 C4 and the ride was horrible. I checked the tire pressure and the previous owner had the tire pressures between 45 - 48 psi. After I lowered them to the under 150 mph recommended 30 psi, the car felt a lot better. You may have other issues, but running the correct tire pressure can really make a huge difference.

Tires and shocks are the way to go.

I was really off-put by the tough ride. The tires looked good, even though they were 16 years old, and the shocks showed no sign of leakage.
The new tires kept the car from bouncing off the pavement when hitting bumps. And the new shocks softened the ride as well as kept it on the road.
The shocks cost less than $200.00, and they went from box to car in less than two hours. And I'm no mechanic by any means.

For point of reference, I had a 95 that was in prime condition. I believe by the time C4s developed to the point of the 95+ cars, the ride issues (hard/harshness) was pretty well sorted out: lower spring rates, different shocks, etc; i.e., firm, but NOT harsh at all!
If your ride is as hard as "Clang! I just ran over a dime, and it was on HEADS!!", then for sure you have issues to address!

Remember it is a sports car "not a Volvo"
you cannot expect a smooth comfortable ride in a C4.... especially with a Z51 suspension package.
You should try an early 1984 C4, race car Z51 suspension to impress the media with 1G lateral acceleration capability.
Have one of those Z51 options and have a chiropractor on speed dial.
