2. I did check the centering rings and they were seated properly (before I retorqued the lugs I took the wheels off for final inspection).

3. AFS had mailed 4 centering rings. They all looked exactly the same. Andrew are you sure two are different and are meant for the rears? What size exactly are the fronts are rears (for my information)

4. The tire shop did use the hunter 9700 with road force and even unmounted one of the tires, rotated the tire a few degrees and then remounted so that it takes less weight.

5. The AFS wheels and tires came premounted but for my sanity I had them rebalanced.

6. I am tempted to try the 17s back on (front) to see if the shimmy is gone. Perhaps the OEMs being smaller do not exhibit or amplify the shimmy that much.
