Shaking over 70 mph, soooo confused

[fullthrottle52]

Check over on the general discussions section and do a search for "tire problems".
I posted a similar problem recently and chased the monkey for 4 months. I was just about to buy new rims for the front (tire place told me I had bent rims) when I took the car to a tire store with a road force balancer. They gave me back my car in less than an hour and it ran really smooth. The also found a new tire on the rear that had a high spot in it (Michelin Pilot Sports). Replaced and now all the vibration is gone. Drives smooth as silk.
P.S. I ask the guy who did the balance what he did to make the shakes go away. He just smiled at me and said "I'm just damn good at what I do". End of questions. I just drove it home with a big smile on my face.
