Hello,

Yesterday I took off the rear wheels to get better access to the brakes. What I found was that both metal rings, which go inside the rims, are broken. Here is how they look like:



Could this be a result of some "look at me I'm so cool" kind of driving, I did some time ago? I looks that both parts got the same amount of overload and broke, so I assume, it is probably a result of some jump starts from the traffic lights.

My rims are Cragars, if that helps, here are few pictures:




Probably repairing these rings is not the best idea? Driving without them is even worse idea? Where is it possible to purchase them?

Thanks
