Hi Franc,

Well I'm not sure it has to do with the car being in the air. I store my car for the winter as well but I don't put it on jack stands. Last month we got heavy rain for two days () washed all the salt away!) and then it was nearly 65 degrees and sunny so I couldn't resist the urge. I started the car, warmed it up, drop'd the top, with wing up I went for a ride.

Exactly the same issue you have documented. About 35 to 40 MPH violent vibration. I pulled over in a church parking lot and inspected everything. No visible issues? Got back in about two miles down the road it smoothed out and there were no more vibrations for the next hundred miles?

I just thought it was possibly flat spots because I hadn't moved the car for several weeks. After hearing what happened to you now I'm not sure. Hopefully someone will have some idea of what is caused this?

This is my second Roadster and I stored the first one the same but never had this issue? I'm with you, anyone got an idea?


Respectfully,
