Retarded question about suspention
I've had my "91 for over 2 years now. Never replaced shocks since I've owned it. When driving anywhere from 80 to over 100+ MPH down the highway it seems like any change in the road patterns such as unevenness, bumps, and etc. the car feels like its gonna fly off the road or something. I have a new Lexus IS and it's much smoother at theses speeds on the same road. Shocks perhaps need replaced or any thoughts????

Could be shocks, tires, worn parts, alignment or any combination of the above. Mine gets better, the faster it goes. This is as it should be.

IMO, the notorious part of the gen 4 suspension that needs to be addressed for safe and predictable handling is the rear camber rods. The rubber bushings in these deflect when cornering, the harder you camber, the more Positive camber (tires leaning out at the top) they induce. My vette handled worse than the same year firebird formula that I had ... until I replaced the rear camber rods with the spherical rod end ones. I used the heavy duty racing ones from Vette Brakes, with the extra large rod ends. They work great on the street. These use steel tubes. I wouldn't trust the thin aluminum tubular spherical rod ended ones for this highly stressed part.

Do you where the shocks are?
What tire pressure(s) are you setting?
If your gonna drive a ZR-1, ya gotta be a bit more car savvy brother.

My '84 does the same thing
As long as I keep my foot on the gas my car feels pretty good but as soon as I lift off the gas it seems like it floats around. I've got new tires, replaced most of the bushings in the rear end and changed one wheel bearing. Hasn't helped a thing. I always wanted a Corvette but now I'm wondering why.
