They go in the bearing seat. Basically, they make the gap of the yoyo a little bit larger, and make it a tad more unresponsive. I don’t find them necessary. ---

Well I am actually looking to buy them for my X-Con because as many of you might know, the X-con does not have a wide gap. I am actually forced to only use one O-ring and it’s still a bit responsive. Which I don’t want. If any of you have an X-con or an X-conVict that use shims can you tell me if they help? It would be appreciated. 🙂 ---

It would be appreciated. 🙂 They do help. I had an x-con and put shims in it and it made it more unresponsive. But they do tend to make the yo-yo vibrate more. Just a warning. ---

Yeah, it helps the bearing NOT be so attached to the bearing seat.
