Also, first before replacing your rotors I would definitely have your wheels rebalanced. They can become imbalanced just from wear.
Yes, typo. Thanks. I'm having the wheels rebalanced now and the day I had the dealer install the new ARC-8's and tires, they balanced it and still that evening first drive on the highway, I got the vibe. So at this point, It's got to be the rotors, I would think. Everything else has been checked out and is straight, tight, not worn, etc.
