    Did you ever find the cause? Mine is doing the same thing.

    Nope. Dick Lovett said they could hear a buzz but couldn’t pinpoint it. They also said I could in theory spend thousands trying to track it down but as it wasn’t causing a problem money was probably better spent enjoying the car.

    Well now you’ve got yourself an issue, son. I’m guessing you’ve eliminated the usual suspects?

    I'm going through the checklist. Starting with the exhaust.

    My loudest noise was an exhaust tip, then a heatshield then a stripped bolt. Good luck, let us know how you get on.

    Do you by chance have Capristo exhaust brackets installed? My f430 Spider developed a buzz/resonance at about 3000 rpm regardless of what gear. Of course, I noticed it at lower speeds (~ 30-35 mph in 2nd or 3rd gear). Removing the Capristo brackets eliminated the issue.
