I just installed the hub centric rings. It did fix the vibration everytime I put a brake at 65 to 70 mph. Everything is smooth now. Here are the pictures. If you got aftermarket wheels and got vibration...this is the first step you should do after balance the tires and it still give you vibration. It cost me $39.95 free shipping.
Picture 1. Hub center bore (also called Inner Diameter) without the hub centric ring.

Pictures 2. Just before I put on the ring to the hub center bore.

Picture 3. After I put on the hub centric ring (no adhesive needed, it just stay there)

Picture 4. Close up view. There is NO more gap between Hub Center bore and Wheel center bore (also called outer diameter).
The wheels are now centric to my hub center bore= no more vibration
