I have a 1996 Corvette Limited Edition Model with 27000 miles, 6 speed Lt4 engine, Z51 suspension. My problem, which I believe I have narrowed down is that on very hot days above 80 degrees. The cars suspension becomes very stiff, particularly in the front and the car bounces around like a yo-yo. I have taken it to the dealer and they tell me everything checks out and the car is ok, and they cannot find anything wrong. I first thought it was the tire pressure in the tires, but I let all the air out and replaced it with new air and the problem persists. The problem does not happen all the time, it seems to happen just on hot days, it also seems to go away once over 35 miles an hour on the highway. The dealer did tell me that it might be flat spots on the tires from the car sitting and such low profile tires. But I have ruled this out since it does not happen all the time. I don’t see any sensors on the shocks that the computer might control or any other sensor on the tires that might automatically adjust the ride. Does any one also have this problem? Can anyone please help me with this problem. The car is definitely no fun to ride this way especially on hot days when I want to drive it.

Thanks,
Tony
