2005 GT Ragtop with 47K miles has some vibration at 70 MPH.
At all speeds from zero to 65, the car runs perfectly smooth and straight... no alignment issues.
Once I hit 70mph the car has a slight vibration... After I accelerate over 70 (and beyond......) it's completely gone.
The rims are the AM Bullitt (made in China). My local tire/repair shop who mounted/balanced stated he didn't get a perfect balance from these rims.
Q1.) Do you think this is just a balance issue or is there something more sinister?
The suspension is stock, and I have future plans on replacing it (Koni Struts/Shocks, SR Springs and new upper/lower control arms front-rear all from AM), but when I hit a bump (doing normal street speeds of 35 mph) the car travels or jumps a bit.
Q2.) Is this because the suspension is just old and needs to be replace?
I've notice the converties don't feel as stable as the coups, I'm just wondering if it's time to give the suspension a refresh.
