Hi,

It's somewhat difficult to diagnose something which can be so subjective.

That said, it's a '99 (mileage?). This means that there can be some normal wear to any number of the suspension components such as Bushings, Shocks, Springs, etc. None of these things will last forever, and any one of these could be your culprit.

When was the last alignment done? Tires Balanced? Was it a Full 4-wheel Dynamic Balance? (on a Hunter 9XXX Machine?) What size Wheels? It is not at all beyond the realm of possibility that it could be a Rear Wheel alignment issue. How old are the Tires?

From what you describe, it doesn't sound too serious or expensive to correct. Have a Quality Alignment Shop, (not the Tires Plus or Firestone), preferably a Race Shop have a look. They'll probably correct it in no time.

The resonance of the Car you mention can simply be due to the fact that it is a convertible, not as rigid as a coupe. Strut Tower Braces go a long way to improving this. Good Luck!...

Happy Motoring!... Jim'99
