Help! Excessive shaking at 65+





If you have damaged steering /suspension components, all that stuff wont fix that.
If you have the car on the ground and engine running and have someone inside the car turn the steering wheel slightly LEFT & RIGHT,,, while you examine all of the steering components, you might see some damaged stuff..
Look at the steering rack, ball joints control arms, tie rods ect and see if there is any LOST MOTION or deformation when the steering rack TRIES to move the tires. See if the steering rack tries to move within its mounts. IT SHOULDNT!
That's a quick and dirty way if inspecting for damaged parts.

I recently purchased a 1997 corvette with the suspension mode option. When I bought I had a few things fixed. One of the front wheels was bent, so I replaced with an original one, and with 2 new front tires, as well as a full alignment.
At 65+ the car shakes excessively. Since it does have the F45 suspension option, could this have anything to do with the shaking? I don't believe the suspension mode is working, as I've never felt an difference, and the suspension looks to be original. The car has 127k miles.
