John, I had hours and hours on the road to look for what you are talking about with the 3000 to 3300 rpm vibration issues. I do not think this is the problem.
I believe it's wheel related. Worn rubber doesn't help it either.
I'm gonna save up and buy new rims and tires. I really want 18 inch Carrera lights, but I hear the 97's can't support them (bearings go out) although I can guarantee they are lighter than my 17 inch ROH's... which belong on a Trans Am, not a Porsche.
