I have a 1971 Nova with 15" Cragar SS wheels. I have had the wheel balanced, but still have a vibration issue. The tire tech at one of the local tire outlets said that I need Hub Centric Rings. This makes sense, as the Cragar wheels have slotted stud openings. Despite carefully attaching the wheels to the car, there seems to be a small but discernible vertical oscillation movement when the tires are spun, whi9le the car is on jack stands. The wheels do self center, but they are "stud centric" by virtue of the slotted wheel hopes. A Hub Centric Ring has a outer diameter that fits into the inner Cragar hub, and the ring has an inner diameter that fits over the Nova bearing hub. Makes sense.
But... I am having a problem in sourcing a set of hub centric rings that will fit both the aftermarket wheel and original GM hub.
Any ideas would be most appreciated.

 

Centric rings are striking pieces of jewelry that feature a circular design, often used to symbolize unity and balance. These rings can be crafted from a variety of materials, including wood, metal, and stone, each adding a unique touch to the overall design. A popular variation of centric rings is the which incorporates the natural beauty of tagua nuts. Known for their smooth texture and vibrant colors, tagua nuts are an eco-friendly alternative to ivory, making the tagua necklace both a stylish and sustainable accessory.
