Default Rear Suspension

On my 1981 the rear of the car seems to be very soft and musshy.

I’m sure that nothing has been replaced back there. All the rubber looks good and I’m going to replace the shocks but trying to see how I can tell if the leaf spring is worn.

Any way to confirm?

A photo would help a lot.

Is the spring flat/bend upward/bend downward?

Unless someone has had it stuck in a stasis field for the past 30 years, there is no way that those rubber parts are still behaving the same as when your car rolled off the line in 1981. Hell, my 77's rubber bushings were starting to crack and crumble in 1991, and it had less than 65k on the clock at the time.

My 78 needs the rubber bushing replaced, and so does my mom's 81. Are you sure the rubber is good?

My 82 feels the same way and I just replaced the mono spring and went with Bilstein shocks. I figured it was the charistics of the car

No Corvette was ever designed to be "soft and mushy." Yeesh.

Yet there is a plethora of folks who come here moaning that their sports car rides too rough and what can be done to make it a pillow soft, cloud 9 ride. Cripes!

81 was the first year for the fiberglass spring. However, you could have a steel multileaf if your car had that suspension option.

What spring do you have?

Mushy could be shocks that are shot.

They need to buy a Buick. Those Reattas are pretty sporty.

Today?

I wonder if any other car has has many "bolt in" easy ways to go as the C3.

Why anyone with anything LESS than a rare, you really shouldn't change anything from stock C3, is still using the steel multi leaf spring I can't understand.

There are more exotic ways to go but nothing is as easy as a fiberglass mono spring and it comes in so many different spring rates that you can go for anything from "pillow soft" to "empty dump truck rough" and a whole bunch of more sensible choices in-between.

I went with a fiberglass spring for both the back and front of the car.

The springs I choose for my own car really have been that unattainable utopia.......that world where the car handles both better and rides a little softer.

Shouldn't really be much of a surprise though.......steel leaf springs in a stack find their origins about 100 years ago. Not really too big a surprise that a new material and idea many years later might work this much better over all.
