In order for us to help you, you need to answer YAL's question.
Where do you feel the vibration?
In the steering wheel ?
In the seat ?
All of the above ?
I've had wheels balanced with a GSP 9700, and it would not cure my vibration, that was because the machine itself was not calibrated & a brain-dead monkey was operating it.
Lots of $$$$$ wasted there.
Finally took the car to an expert ( with a very old machine ), that balanced my tires to perfection.
